I have the following controller:
public IActionResult Get()
{
var res = GetResult();
// res is a JSON {"hello": "how\are\you"}
return Ok(res);
}
I'm getting in the result:
{"hello": "how\\are\\you"}
How to remove the double slash from the reusult? Why they're being added?
Why they're being added?
Because that's how you print a backslash in JSON. \ is a special character. It pairs with the next character(s) to define what it prints. For example, \n means to add a new line, not printing "\n". \\ means a print a single backslash.
The server (your code) and the client using your application will understand this escape sequence just fine.
These \ are not part of the string but only one i.e. \ is part of string. another \ is added as a escape character only.
if you print this you will only get single slash not double these are just representational value at the time of debug only.
Check live code : here
You don't need to remove them since you have them in json already. If you want to get rid of them fix json of the action
var res = GetResult();
res.Replace("\\"," ");
return Ok(res);
