How do I replace a backslash-double quote with just a double quote?

I have struggled with a simple replace. And need a good solution. Background: It is a xml string encoded with \" and these need to be " to be able to deserialize it with serializer.Deserialize.

I want to replace backslash doublequot with one double quot a string like " \"hello\" " so the string are " "hello" ". The text is long so it is not possible to remove backslash. Thanks for advise. I think it should have been

string s= "\" teetete \"";
string t;
t = s.Replace("\"", @"""");

It's not clear what you want to do, but it sounds like you have an XML string that contains a double-quote character (being displayed as \" in the debugger) and you need to replace it with " to allow the XML parser to understand it. In which case a simple call to .Replace() may be enough (although I imagine in reality there are edge cases that will need to be resolved with something more complex).

Your sample string doesn't contain any backslashes, you are just using it to mask the double quotes. This contains one backslash at the beginning and one at the end:

string s = "\\\" teetete \\\"";

If you want to replace it with a single double quote:

string t = s.Replace("\\\"", "\"");

You have to look click at the loupe in the debugger to see the real value of a string:

That isn't actually encoded with \". That is literally a string whose contents are " teetete ". In order to display it, or compile the string, you have to escape the quotes, which is why you have:

string s = "\" teetete \"";

A string that has backslash quote in it, i.e. \" will actually look like this:

string s = "\\\" teetete \\\"";

That is, one set of \\ for a literal \ and \" for a literal ". If you want to replace that, then it's almost what you wrote:

string t = s.Replace("\\\"", "\"");

That will convert any \" in your string to ", which I'm guessing is what you actually want, unless you're printing it out into some VB.NET code, in which case "\"\"" would be more appropriate.
