c# replace " characters

Question

I am sent an XML string that I'm trying to parse via an XmlReader and I'm trying to strip out the " characters.

I've tried

.Replace(@"", "")
.Replace("\''", "''")
.Replace("\''", """)

plus several other ways.

Any ideas?

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.)
