来自此处.

问题.某个接口.返回错误消息用的是400.所以必须知道具体的内容.

using System;

using System.IO;

using System.Net;

 

public class Test

{

    static void Main()

    {

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://csharpindepth.com/asd");

        try

        {

            using (Stream data = request.GetResponse().GetResponseStream())

            {

                using (StreamReader reader = new StreamReader(data))

                {

                    string text = reader.ReadToEnd();

                    Console.WriteLine(text);

                }

            }

        }

        catch (WebException ex)

        {

            HttpWebResponse response = (HttpWebResponse) ex.Response;

            Console.WriteLine("Error code: {0}", response.StatusCode);

            if (response.StatusCode == HttpStatusCode.BadRequest)

            {

                using (Stream data = response.GetResponseStream())

                {

                    using (StreamReader reader = new StreamReader(data))

                    {

                        string text = reader.ReadToEnd();

                        Console.WriteLine(text);

                    }

                }

            }

        }

    }

}
