I'm very new to C# and want to learn how to make HTTP requests. I want to start really simple, although that is currently evading me. I want to just perform a GET on, say, google.com. I created a command line application, and have this code. Not sure at all which usings are required.

I tested it by writing to the console, and it doesn't get past the response. Can somebody please clue me in? I'm looking to do some simple curl type stuff to test an existing API. Thank you for your help.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.IO;

namespace APItest
{
    class testClass
    {
        static void Main(string[] args)
        {
            string url = "http://www.google.com";

            Console.WriteLine(url);

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            Console.ReadKey();
        }
    }
}

我会考虑使用HttpClient来代替，它是为了在 .net 4 中更容易调用 rest API 而创建的。它还支持async和await.

你可以这样称呼它（使用异步）：

async Task<HttpResponseMessage> GetGoogle() {

    HttpClient client = new HttpClient();

    Uri uri = new Uri("http://www.google.com");

    var result = await client.GetAsync(uri);

    return result;
}

我不建议使用 HTTPWebRequest/HTTPWebResponse 在 .Net 中使用 Web 服务。 RestSharp更容易使用。

您需要阅读回复：

var stream = response.GetResponseStream();

然后你有你的流并用它做你需要的事情。 GetResponseStream
