 string response = PostRequest(url, consumerKey, secretKey, jsonString); // Function Call}

   public static string PostRequest(string url, string consumerKey, string secretKey, string jsonString, string outputFormat = "application/json")

                dataStream.Write(byteArray, 0, byteArray.Length);
                dataStream.Close();

                var response = request.GetResponse();
                var respString = new StreamReader(response.GetResponseStream()).ReadToEnd();

                return respString;
            }
            catch (Exception ex)

推荐答案

建议：

- 永远不要在发布给公众的代码中提供您的用户ID和密码。从来没有，无论如何。



如何解决错误：



由他人解决：

- 在代码中给出错误位置，以帮助帮助者找出问题所在。

- 一些句子解释代码的作用不会造成伤害。



自己解决：

- 学习使用调试器，以及错误信息和错误位置，你必须能够解决问题你自己。

- 错误信息告诉你出了什么问题。

自己解决问题会产生次要影响，它可以提高你的编程技巧。



错误发生在被调用函数中， g 是该函数的参数，没有原型就无法提供帮助。

Advice:
- Never ever give your user id and password in code posted to public. Never, no matter what.

How to solve the error:

To solve by others:
- Give error location in code in order to help helpers to figure where is the problem.
- A couple sentences explaining what is doing the code would not harm.

To solve it yourself:
- Learn to use the debugger, along with the error message and error location, you must be able to solve the problem yourself.
- The error message tells you what is wrong.
Solving the problem yourself have a secondary effect, it improve your programming skills.

The error occur in a called function and g is a parameter of that function, no help is possible without prototypes.
