Answer 1

You can use String.Trim do not forget to assign the result back to string variable. string in c# are immutable and we need to assign the changed value back to the variable.

jsonStr = jsonStr.Trim( '"' );

If you have multiple characters you can use overloaded String.Trim(Char[])

jsonStr = jsonStr.Trim( new Char[] { '"' } );

Edit in OP there is only on double quote in beginning and end of string but if we have multiple double quotes in beginning and end and we just want to remove only first and last then we can use string.Substring

jsonStr = jsonStr.Substring(1, jsonStr.Length-2);

Answer 2

this is help for me.

        responseContent = responseContent.Substring(1, responseContent.Length - 1);
        responseContent = responseContent.Substring(0, responseContent.Length - 1);

I'm assuming " and \\" are actually in the string, and not an artifact of embedding that string in source code or displaying it in the debugger.

In that case, you don't want to just remove the initial and trailing " , but you need to treat it as a json string and decode it. This will also replace the encoded \\" by plain " inside the string.

If you're using Newtonsoft Json:

decodedString = JsonConvert.DeserializeObject<string>(jsonString);
