如何删除JSON字符串中的开头和结尾的双引号和所有反斜杠-C＃

Question

For performing a rest API call with C# I have to serialize a dictionary with parameters. These parameters have to be placed inside the body of the request as JSON.

The API call is done with the help of RestSharp. And the send string is checked with fiddler.

request.AddBody(_jsonrequeststring);

The problem is that the API is very picky, it doesn't accept break points (backslash) and it doesn't accept double quotes on the beginning and on the end of the JSON string.

So here what it's expecting:

{
    "ConsumerToken":"aconsumertoken",
    "UserId":"email@web.com",
    "PasswordSha256Base64":"apassword"
}

And this is what I'm sending:

"{ConsumerToken:\"aconsumertoken\",UserId:\"email@web.com\",PasswordSha256Base64:\"apassword\"}"

I'm able to remove the \\" but when it sends that string it also returns an error.

"{ConsumerToken:aconsumertoken,UserId:email@web.com,PasswordSha256Base64:apassword}"

Is it even possible to just remove the \\ and opening and closing double quotes? And if so how? I just can't seem to wrap my head around it.

The complete call:

userhandler.cs

public static object Login(string uname, string pass, string conTok)
{
    Dictionary<string, string> loginDictionary =
    new Dictionary<string, string>();
    loginDictionary.Add("ConsumerToken", conTok); 
    loginDictionary.Add("UserId", uname);
    loginDictionary.Add("PasswordSha256Base64", pass); 
    string jsonRequestString = JsonConvert.SerializeObject(loginDictionary);

    Proxy proxy = new Proxy(jsonRequestString); 
    return proxy.Execute();
}

Proxy.cs

public class Proxy
{
    const string BaseUrl = "API url";
    const string ActionUrl = "API action url";

    string _jsonrequeststring; 

    public Proxy(string json)
    {
        _jsonrequeststring = json;
    }

    public Object Execute()
    {
        var client = new RestClient(BaseUrl); 
        var request = new RestRequest(ActionUrl); 

        request.RequestFormat = DataFormat.Json;
        request.AddBody(_jsonrequeststring);

        request.Method = Method.POST;
        var response = client.Execute(request);

        var content = response.Content;

        return content;
    }
}

It looks like you're adding the body content as a string, which means that it'll be encoded as a string by RestSharp. If possible, try adding the object itself and let RestSharp handle the serialization etc:

var obj = new {
                  ConsumerToken = "aconsumertoken",
                  UserId = "email@web.com",
                  PasswordSha256Base64 = "apassword"
              };
request.AddBody(obj);

If you must use a pre-serialized JSON string for some reason, you should be able to do it like this:

request.AddParameter("application/json", _jsonrequeststring, ParameterType.RequestBody);

[NB: I haven't actually tested either of these suggestions, but I think they should do the trick]
