Hi All,
I have several string which I got from a file read.
Now I have to show them in a single text box which have multi-line properties
below I had given code

string FstArray = splite[0];
                    string SndArray = splite[1];
                    textBox2.Text = FstArray;

only third,fourth and seventh string should come one by one (not same line) in a particular text box

Thanks To All
Indrajit

Solution 3

Use System.Text.StringBuilder and concatenate the strings using System.Environment.NewLine as a separator.

Do not use "\n", "\r" or "\r\n" for a line separator — this is not portable!

C#

void PopulateTextBox(string[] source, TextBox destination) {
    System.Text.StringBuilder sb = new System.Text.StringBuilder();
    int count = 0;
    foreach(string line in source) {
        sb.Append(line);
        if (count < source.Length - 1)
             sb.Append(System.Environment.NewLine);
        ++count;
    }
    destination.Text = sb.ToString(); 
}

Couple of problems here: repeated "+" is not effective because string is immutable; the intention is to use the array as data input.

My solution is correct, the one by Prerak is just perfect.

Hello I think u should write code like below

C#

string str = "Hello, Hi, Hoo";
           string[]  strar = str.Split(',');
           foreach(string ss in strar)
           {
               TextBox1.Text = TextBox1.Text+ss + Environment.NewLine;

           }

Solution 1

Assuming that splite is a String array, this single line should work fine.

textBox2.Text = String.Join(System.Environment.NewLine, splite)

It shows all line But I need only third,fourth and seventh line how can I do that please help

Prerak Patel 7-Jul-11 5:33am

Then you need to append it like textBox2.Text = FstArray + Environment.NewLine + SndArray + Environment.NewLine + ... ;

IndrajitDasgupat 7-Jul-11 5:39am

yes it is working but last one is taking a junk character

IndrajitDasgupat 7-Jul-11 5:47am

how can I remove the junk character

Prerak Patel 7-Jul-11 5:53am

Which junk character? Share your code.

IndrajitDasgupat 7-Jul-11 6:13am

Below I m giving code please check
string allData = str;
string[] splite = allData.Split('\n');
string FstArray = splite[3];
string SndArray = splite[4];
string ThrdArray = splite[7];
textBox2.Text = FstArray + Environment.NewLine + SndArray + Environment.NewLine + ThrdArray;
r.Close();
fs.Close();

Prerak Patel 7-Jul-11 6:16am

It is fine. You shouldn't get any junk character unless splite[7] itself contains it. Debug your code carefully.

IndrajitDasgupat 7-Jul-11 6:31am

yes you are write splite[i] is contain junk character but the last one is showing junk character in the concatenation.How can I remove that can u give me some idea Sir ji

Prerak Patel 7-Jul-11 6:36am

Seems like your junk character is \r.
Try string[] splite = allData.Split(new char[] { '\r', '\n' });
