No need to replace backslashes. For string literal we need to add \\ (backslashes). However you can use String.Replace() method.

Thanks for reply,I tried it but shows error in "\\".Pl resolve it.

string p1=textBox4.Text .ToString().Replace("\","\\");
                 MessageBox.Show(p1);

Hi, adobe71.
C# uses the backslash to escape characters, so "\\" is equal to \ literal, and "\" results in error, because you trying to escape the second quote and your string literal remains "unclosed".

You have 2 ways to go:
1. As you can see, double backslash results in a single one. So, to have \ ? you have to write \\ . 4 backslashes to result "\\" .. and so on.

2. You can use @ before your string literal, so the compiler won't try to get the control sequences from your string (based on the backslashes) and would treat your string same, as you write it (so the @"\" results into \ ).
