How can I separate each character in a string and place each character in a separate label?

Hello, I am using using WinForms.

My objective is to split a string of 18 characters so that each character is seen as a separate value.

For example, if 232223232223323222 is my string, I need to split it into 18 separate strings:
2
3
2
2
2
3
2
....and so on.

How can this be achieved?

I have tried several methods:

C#

String a = 2223232223323222;
            a.ToCharArray();

            richTextBox1.Text = richTextBox1.Text + a;</pre>

and

C#

string input = 2223232223323222;
            double parts = 1;
            int k = 0;
            var output = input.ToLookup(c => Math.Floor(k++ / parts))
                .Select(b => new String(b.ToArray()));

            totalres.Text = output.ToString();

To be honest, i'm not even sure what I am doing.

After each value is its own string (18 strings) how can I place each one into its own label?

I only request that level of detail in your explanations is medium-high.

Thank you!

Do you main label, as in the concept of labeling something? Or, an object of type Label?

If you're talking about the concept, it might be easier to place individual items in a list control of some kind.

I am talking about the object.

Solution 2

Hello

Have a Panel and:

C#

string a = "2223232223323222";

char[] chars = a.ToCharArray();
for (int i = 0; i < chars.Count(); i++)
{
    Label l = new Label();

    l.Text = chars[i].ToString();
    this.MyPanel.Controls.Add(l);
    l.Top = i * l.Height;
}

or you can do it without Panel:

C#

this.Controls.Add(l);

If I were you, I would create a method to figure out the accurate coordinate for Labels

C#

private void Form1_Load(object sender, EventArgs e)
{
    string a = "2223232223323222";

    char[] chars = a.ToCharArray();
    for (int i = 0; i < chars.Count(); i++)
    {
        Label l = new Label();

        l.Text = chars[i].ToString();
        this.MyPanel.Controls.Add(l);
        SetCoordinate(l, i);
    }

}
private void SetCoordinate(Label lable, int i)
{
    // some code to computing
}

But:
If You have many Labels in your Form, then tag them.
Set their Tags to 0, 1, 2, 3 and ...
Then:

C#

private void Form1_Load(object sender, EventArgs e)
{
    string a = "2223232223323222";

    char[] chars = a.ToCharArray();
    for (int i = 0; i < chars.Count(); i++)
    {
        Label l = FindLabel(i);
        if (l == null)
            continue;
        l.Text = chars[i].ToString();
    }

}
private Label FindLabel(int i)
{
    foreach (Control c in this.Controls)
    {
        if (c.Tag == null)
            continue;

        int k = 0;
        if (!int.TryParse((c.Tag).ToString(), out k))
            continue;

        if (c is Label && k == i)
            return (Label)c;
    }

    return null;
}

Thank you, I will try this now. I already have the labels on the form, the only thing that needs to change is the text. But I will try this now. Let you know soon.

Shahin Khorshidnia 27-Mar-12 18:51pm

Ok, Please read updated solution.

vlad781 27-Mar-12 18:55pm

Thank you, will let you know how it goes.

Shahin Khorshidnia 27-Mar-12 18:59pm

Ok

vlad781 27-Mar-12 19:11pm

Well, I have tagged every single label (0-17, 18 total), but I am confused as to what I should do now. Is there anything in the code you provided that I should adjust to fit my needs? or is it ready to go "as it is now"?

EDIT: When I simply copy and paste your code, nothing seems to happen.

I appreciate your effort.

Shahin Khorshidnia 27-Mar-12 21:07pm

you must add the labels as children of the form. Maybe you added then as children of a Panel or something else.
If you did it for a Panel then you must change the code.
For example the Panel name is "MyPanel":

foreach (Control c in this.MyPanel.Controls)
{
...

Sergey Alexandrovich Kryukov 27-Mar-12 19:28pm

My 4. No need to make a char array and use "for". A simple foreach traversing the string itself works, please see my answer.

Shahin Khorshidnia 27-Mar-12 21:03pm

Thank you for the attention SA
I used "for" because I needed a counter to initialize lables.

And Thanks for +4

Solution 1

What's wrong with this:

C#

int top = 0;
int gap = 4; //for example...
foreach (char ch in a) {
    Label label = new Label(); 
    label.Location = new Point(0, top);
    label.Text = ch.ToString();
    parent.Controls.Add(label);
    top += gap + label.Height;
}

[EDIT]

As OP still does… who knows what, I added to detail with calculation of position. Let's assume it all is put on some panel of appropriate size, so left-topmost position is {0, 0}.

label.Text = ch.ToString();
Will this allow each label to have a separate string?

EDIT:

Well, I tried this (but with an existing label) and the label either disappeared or just went blank.

Sergey Alexandrovich Kryukov 27-Mar-12 19:27pm

Yes. How could it be "non-separate"? you create an individual label per character, is that what you want? (I have no idea why, by the way; let's say, just to get some understanding...)
--SA

vlad781 27-Mar-12 19:36pm

I'm sorry, but something doesn't seem to be working.

I am attempting to use my current labels, instead of creating more:

foreach (char ch in a)
{
wdval1.Text = ch.ToString();
wtval1.Text = ch.ToString();
wdval2.Text = ch.ToString();
inval1.Text = ch.ToString();
cyval1.Text = ch.ToString();
cyval2.Text = ch.ToString();
inval2.Text = ch.ToString();
}

Shahin Khorshidnia 27-Mar-12 21:17pm

I think SA solved your critical problem (Creating Lables in a loop) that's why I voted 5.

And about " //etc....": It's not too hard to do it yourself as your style. But if you want any idea you can look at my solution too :D

Sergey Alexandrovich Kryukov 27-Mar-12 22:53pm

Thank you, Shahin.
I added some detail on OP's request.
--SA

Sergey Alexandrovich Kryukov 27-Mar-12 21:19pm

Are you serious? And how are you going to find correspondence? No; I gave your the solution, just do it. Arrange each label (positions, etc.), do parent.Controls.Add(label), where "parent" if the control (Panel, Form...) to become a parent of all those labels.
And, if and when you got it, please accept the answer (green button) -- thanks.
--SA

vlad781 27-Mar-12 22:06pm

Just to clarify, what goes in place of //etc?

Sergey Alexandrovich Kryukov 27-Mar-12 22:51pm

Please see more detail in the code sample above.
--SA

vlad781 28-Mar-12 11:25am

Well, I did as you said, but all of the labels have the text "2" in them. That is the first number of the string.
string a = "2323232223323222";

int index = 0;
foreach (char ch in a)
{
Label label100 = new Label();
label100.Location = new Point(206, 188); //calculate depending on index
label100.Text = ch.ToString();
this.Controls.Add(label100);
label100.BringToFront();
label100.ForeColor = Color.Black;
label100.BackColor = Color.Transparent;
label100.AutoSize = true;
label100.Enabled = true;
++index;

Label label101 = new Label();
label101.Location = new Point(251, 188); //calculate depending on index
label101.Text = ch.ToString();
this.Controls.Add(label101);
label101.BringToFront();
label101.ForeColor = Color.Black;
label101.BackColor = Color.Transparent;
label101.AutoSize = true;
label101.Enabled = true;
++index;
}

Sergey Alexandrovich Kryukov 28-Mar-12 11:35am

I don't know what to do with you. I explained everything... Probably you just have very little experience. You put an identical but different label twice at the same location; you put all labels at in the same location. Are you seriously unable to spread them horizontally or vertically. You use hard-coded integer values 206, 188, 251, 188 -- a big no-no. You give variable ugly names like label100 or label101. Why?
--SA

vlad781 28-Mar-12 12:19pm

I just do not understand why each label created does not correspond with the different characters in string a.

I also tried to change the text in the labels that already exist, and it still does not work, they all change to "2" instead of "2","3","2"...

Sergey Alexandrovich Kryukov 28-Mar-12 21:22pm

Why? You created some labels with designer, how can they "know" they would correspond anything in your code? Just use simple logic. I have you exact advice what to do. Perhaps, you should understand: programming is not done via the designer. In this particular case: none of those '2', '3', '2' labels should be created in designer. Remove them all; they will be created in the code I've demonstrated to you.
--SA

vlad781 28-Mar-12 22:04pm

yes I removed them all and used the code you provided. I have 18 labels being created using the code you provided. And all of them show as "2", the first character in the string.

Sergey Alexandrovich Kryukov 28-Mar-12 23:06pm

It cannot be... do you see them all at the same time? can show the code?

This works great, except the the fact that I need each label in a specific place. Each location has absolutely no correlation with one another. My code above was just a test.
I need the following locations:

188,81
251,81
311,95
133,113
225, 122
290,142
348,135
118, 166
169,159
300,190
355, 192
127, 219
179, 212
246, 232
325, 247
174, 265
227, 277
277, 280

As you can see, each label is located in its own unique location. There is absolutely no correlation. The code above that I provided only was a test.

I appreciate your help.

I don't know why. I think you need to explain why. If you do something weird, you really have to, otherwise, who will care to answer? What if the original idea is wrong. Anyway, it's hard to understand what's the problem? You can have array of those Point, read it from file, whatever...
