Capture a certain number of characters from text box.

Hi again,

I want my text boxes to break down the text within them into different variables. For example, if I paste 3000 characters of text into the text box I want the first thousands to var = text1, the second thousand to var = text2 etc...

I use the following code to save all the text to a variable at the moment:

C++

public void button1_Click(object sender, EventArgs e)
       {
           var list = textBox1.Text;
       }

One method I was thinking was to capture the first 1000 characters, save them to a var and then delete them. Then just loop that until all the text is gone.

Any other methods?

Thanks in advance.

Solution 1

Use String.Substring Method (Int32, Int32)[^].

[Agent_Spock]

Example in your case:-

var list = textBox1.Text.Substring(0,1000);

This would give you first 1000 letters and for second one thousand use

var list = textBox1.Text.Substring(1000,1000);

In what context do I use it?<pre "c#">
string testlist = Substring(0, 1000)textBox1.Text;</pre>
, that returns errors.

You should do like...

string testlist = textBox1.Text.Substring(0, 1000);

Sweet works fine, the issue now is that if a bulk of text is under 1000 it will not fire.

It will work if the length is 1000 or more.
Else, you need to specify the length instead of 1000.

Please accept the answer.

Thanks,

Annoyingly I can't find anywhere if I can do for example: Substring(0, ANYNUMBER);
