Answer 1

Use either single-quoted characters, @verbatim strings, or properly escape the characters:

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

Explanations:

1. Single characters are delimited with single-quotes characters '. The same backslash-escape rules from literal strings apply to literal characters, except that you can specify a double-quote directly (i.e. '"' instead of '\"').
2. Verbatim strings in C# do not have backslash escapes (i.e. backslashes are interpreted literally) making them useful for file-paths. Verbatim strings do allow you to escape double-quote characters by doubling them up, like in VB's strings, e.g. @"""" is a string containing a single double-quote character, similarly @"foo""bar" is a string with a single double-quote between "foo" and "bar".
3. Otherwise, with normal strings, use backslash to escape any special characters and backslash itself.

Answer 2

this should do it - need to escape the correct characters.

string str = jsonstringdata.Replace("\\","\"");

Answer 3

string str= jsonstringdata.Replace("\\","\"");

Answer 4

Characters must be escaped correctly. Look here for some more knowledge on JavaScript strings and how to escape the correct characters.

string result = yourString.Replace("\\","\"");

Answer 5

You need to handle escape sequences correctly. Use a \\ for finding \ and \" for replacing each \ with ". See the following link http://msdn.microsoft.com/en-us/library/aa691087(v=vs.71).aspx

string input = @"\a\\\\";
char replaceble = '\\';
char replacingChar = '\"';
var output = input.Replace(replaceble, replacingChar);

Answer 6

You need to escape the slash and quote characters.

var jsonStringData = "{ Hello\\World }";

string str = jsonStringData.Replace("\\", "\"");

// output of str = { Hello"World }
