Question

I have an array from the dataTextBox field (3 lines).
And I need to delete first symbol in each line.
I’m trying to do it with only line line, but I cannot. This code doesn’t do anything.
How to write correct code? Thank You!

var lines = this.dataTextBox.Lines; 
var sLines = Convert.ToString(lines[0]); //Converting first line to "String".
char[] ch = sLines.ToCharArray();        //Converting first line to "CharArray".
char s = sLines[0];                      //I took the first letter from first line.
string x = Convert.ToString(s);     //Converting to "String" the first letter from first line.
string b = x.Replace(x, "");       //Replacing the first letter from first line on "" symbol.
this.dataTextBox.Lines = lines.ToArray();

this.dataTextBox.Lines = this.dataTextBox.Lines.Select(s => s.Substring(1)).ToArray();

By the way… your code does something, but you assign lines to this.dataTextBox.Lines although you never changed lines. The change is in b only…
