I have a json string like this: {\"active\": true} and I want replace for this {"active": true}. How can I do that in c#?

I tried jsonString.Replace("\\", ""); jsonString.Replace(@"\", ""); jsonString.Replace(@"\"", "");

nothing worked

  • Are you absolutely sure that the original string contains slashes `\ ` before each quote `"`? – degant May 30 '17 at 18:39

    How do you know that you have that backslash as part of the string? Are you looking at the string variable containing the json **using the debugger**? If so then the backslash characters are just the debugger being "helpful" in terms of trying to show you how you would declare a constant in C# to produce that string, but the backslash characters aren't really part of the string. – Lasse V.

    I am also assuming that you assigned the *result* of calling `Replace` to a string variable? `.Replace` won't *change* the string you call it on, it will return a new string with the changes. ie. this will work: `jsonString = jsonString.Replace(...);`, this will not: `jsonString.Replace(...);` – Lasse V.

Since you want replace \" to " you can use Replace.("\\\"", "\"").

You need escape special characters like \ and ". So \ becomes \\, " becomes \", and \" becomes \\\".

Check Regex.Unescape(string) method. This method returns a new string without escape character.
