Error: Cannon Convert from string for char

Code Example 2:

String test= json.Replace("\"",""");  

Error: Syntax Error ',' expected

Answer 1

This is a char literal: '"' . Which as the error states is not a string and you're trying to use it as a string .

This is a syntax error: """ . Because string can't contain an un-escaped double quote. Otherwise it looks like it's terminating the string, and there's an errant extra double quote.

It sounds like what you're looking for is this:

Replace("\\\"", "\"")

Notice how both the \ and the " are escaped in each string literal. This would replace instances of \" with instances of " . You can also just replace \ with nothing to achieve the same result:

Replace("\\", string.Empty)

Unless the full string has other instances of \ that you don't want replaced, of course.

As an aside, it's worth noting that the variable name json implies that this is specifically encoded data, and this direct string manipulation might not be what you really want in the first place. Depending on what you're trying to do, deserializing the JSON data may be cleaner.
