在RESTSHARP中使用数组[long]正文的http请求

Question

Jarray i是从文件中读取的，这是内容： [915417,915418,915419]

这是我的代码：
JArray i = HELPERS_Read_InputJArray_File（input，strEdit）;

        IRestResponse resp = null;
        IRestRequest request = null;
        var auth = "Bearer " + api.accessToken;
        ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
        var client = new RestClient();
        client.BaseUrl = c.mySiteUri;

        //body setup
        try
        {
            request = new RestRequest(api.HTTPRequestAPI, Method.POST);

            request.AddHeader("Authorization", auth);
            request.RequestFormat = DataFormat.Json;

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

            resp = client.Execute(request);
        }
        catch (Exception e)
        {
            Console.Error.WriteLine(e);
        }

问题是编译并返回200，但它没有用。
