string replace() problem

[sysmatrix]

string aa = "\document\test"; aa = aa.Replace("\", "\\"); --- this line C# doesn't like it?? I want to replace '\' in string aa to "\\". How to do it?

You have to escape your chars :rolleyes: Alex Korchemniy

I suspect the problem is that \d and \t are valid escape values, so you've not realised the problem. To put a \ in your string, either put two or, ( my preferred option ), use @. With @ at the start, everything is literal, the only escape is double quotes to do quotes. string aa = "\document\test"; The value here is ocument test, where the spaces are a tab string aa = @"\document\test"; string aa = "\\document\\test"; These both set the string as you'd expect Christian Graus - Microsoft MVP - C++

If you have it already and want it to be replaced now,you may use the StringBuilder class that will assure that it's been replaced.

string aa = @"\document\test"; aa = aa.Replace(@"\", @"\\") ; Sanjay Sansanwal www.sansanwal.com

string aa = @"\document\test"; //than use aa = aa.Replace("\\", "\\\\"); //or aa = aa.Replace(@"\", @"\\"); //both output is: \\document\\test Trick: If U want to use \ in strings U must duplicate it, or use @ before teh string. I hope it helps. Nemo
