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);

}

}

}

}

}

}
