Were you trying it like this:
string text = GetTextFromSomewhere();
text.Replace("", "");
text.Replace(""", "");
? If so, that's the problem - Replace
doesn't change the original string, it returns a new string with the replacement performed... so you'd want:
string text = GetTextFromSomewhere();
text = text.Replace("", "").Replace(""", "");
Note that this will replace each backslash and each double-quote character; if you only wanted to replace the pair "backslash followed by double-quote" you'd just use:
string text = GetTextFromSomewhere();
text = text.Replace(""", "");
(As mentioned in the comments, this is because strings are immutable in .NET - once you've got a string object somehow, that string will always have the same contents. You can assign a reference to a different string to a variable of course, but that's not actually changing the contents of the existing string.)
