Your current list l :
{"A","C","D"}
your instruction:
l.Add("B");
your new list l :
{"A","B","C","D"}
I believe that this is what's your mind trying to achieve.
In fact, I can only think of 2 appropriate ways to fulfil such a task.
1. SORT IT:
Yes, just add your new item normally. Once you do, sort your collection.
Tip: do not call the sorting instruction each time you update the ObservaleCollection, do it once you add all your items.
c# - How to sort ObservableCollection alphabetically? - Stack Overflow[^]
2. PLAY WITH IT:
Write a for loop that runs through the contents of your ObservableCollection. Within each step, a comparison will be done. You will compare your new item's name with each item, once you find a match, push all your items starting from that position to the right side of your collection.
Sample:
Here is your list:
• A
• C
you add a new item: l.Add("B"):
• A
•
• C
the C got pushed down because C's position is greater than B's.
C's old position will be reserved, B will be added to it.
• A
• B
• C

Use design patterns in the game and ensure a rollback
Send a console implementation of the game patches. Ensure that the size of the field is selected and the level of difficulty (how much the board differs from the state of the "victory"), make it possible for the game to become more complicated when a certain amount of random moves takes place instead of the user's turn. Realize the possibility of canceling moves.
The patterns are expected: Singleton, Factory method, Team, Memento.

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

What OG said, with two addendum that will keep other developers from murdering you in the future:
- Use meaningful names in your source code. When you find yourself naming classes things like "repeat" or "Game2" you need to re-evaluate life a little.
- Don't use exceptions for flow control. Never. Never ever.

There is an implementation of the game, you need to roll back the previous move, choose the level of complexity (the size of the playing field 3x3, 4x4), using the Singleton patterns, Factory method, Command, Memento, help.

Hi,
I want to compose message while getting part of the message from excel column data where i should be able to put any column on any part of the message, example,if i have excel with 2 columns, i should be able to compose message as below:
Hello {Name}, Kindly renew your license no {licenseNo}
or
Your license {licenseNo} expires on 28/09/2017. Thank you {Name}.
Where {Name} and {licenseNo} will be obtained from excel file.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.
So when you give us no real information, we can give you no real help.

Hi,
Maybe this will help in better explaining what i wish to achieve.
I have excel document containing Cell Numbers and Names of customer. I want to be able to write custom text messages to all customers by concatenation typed text and data on excel such that i will be able to send same message to all the customers on the list for example. I will type "Hello" then insert the column name {Name} and proceed to add more text. This should ready "Hello Mike" where Mike is obtained from say cell A2 on my excel.
I am using C# and I have designed form as follows:
1. Option to select the excel with the cell numbers and name.
2. Text box, where am typing my text.
3. I have drop down list that populates the column headers from excel (eg Name, cell number).
4. I have a multi line text box where my messages will be displayed
I wish to compose my message as follows:
a. Enter text eg "Hello" and press add text to add text to the multi line text box
b. Select the column eg Name and click on Add Column to add column variable to the multi line text box
c. The text area should show 'Hello Mike' generated by Hello {Name}.
Am stuck at the point of merging/concatenation my typed text and data from excel to form one complete message.
Here is the screenshot of what i have done so far.

So you can read the data from Excel ok, and - given the cell name - access the column.
But you are having problems replacing the text? That's trivial, compared to the excel bit...
The way I'd do it is to start with a regex: scan the input text for "{...}" data, and extract the content as a column name:
(?<ColName>{.*?})Will do it.
The Matches collection will give you the name of column in Excel, surrounded by the curly brackets. Read that column from your Excel data, and use string.Replace to change all instances.

I've never seen anything like this, but I guess it's similar to a JQuery Json request in which you have a Url and the data is the querystring.
So for an example, https://secure.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=<xml> is simply the request and you wait for the response on the XML page.
I have no clue how to transmit this and get the response XML. Just looking for suggestions.
I tried this but it just returns the request.
WebRequest request = WebRequest.Create(endpointUrl + txn);
WebResponse response = request.GetResponse();
Console.WriteLine(response.ResponseUri);
If it ain't broke don't fix it
|
|

|

I have this working for now, but it seems overkill. endpointUrl is the URL and txn is the XML, rxn is the return string to deserialize.
var httpWebRequest = (HttpWebRequest)WebRequest.Create(endpointUrl + txn);
httpWebRequest.ContentType = "application/xml";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{<br />
streamWriter.Write("");
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
rxn = result.ToString();
}
If it ain't broke don't fix it
|
|
|
|
|
Would these encodings be the fault of the way I'm transmitting this from my previous post?
<MailService>Priority Mail Express 2-Day<sup>™</sup></MailService>
If it ain't broke don't fix it
|
|
|
|
|
the encoded stuff was just a trademark.
Works good enough now to finish the API
If it ain't broke don't fix it

hi thnx for helping me in past question
so i Reach here [ex image]
by using this code
private void Form1_Load(object sender, EventArgs e)
{
string img = @"D:\Capture1.PNG";
Bitmap bmp = new Bitmap(img);
pictureBox1.Image = Image.FromFile(img);
int w = bmp.Width;
int h = bmp.Height;
int f = 1;
Random rr = new Random();
for (int y=0;y < h ; y++)
{
for (int x=0 ; x < w ; x++)
{
int a = rr.Next(256);
int r = rr.Next(256);
int g = rr.Next(256);
int b = rr.Next(256);
bmp.SetPixel(x, y, Color.FromArgb(a, r, g, b));
}
}
pictureBox2.Image =bmp;
}
but the problem is the code chose random value to each pixel
how can i chose the value of the pixel and not make it random ?
|
|
|
|
|
Use Bitmap.GetPixel instead of Random.
I can't help thinking that if you invested as much work in thinking about the problem and actually looking at your code as you are in asking questions, you would get these tasks done a lot quicker and easier - this isn't complicated stuff you are doing here...

Dear All,
I have export one graph from placeholder by using save image file.
but i want export whole placeholder with graph in excel sheet like grid view export.
Please help me.

hi
I have a image
I want to change every pixel of this image to a different color
I know that every pixel in the picture is a number
I want to change the pixel color by changing its number by mathematical equation
for example
The original pixel number + number I chose
This process applies to every pixel in the picture
how i can do that

There's a bunch of articles on image processing around here, like this series[^].
