c# - python 的 "urllib2"在 dot net 中的等价物是什么？

Question

我是 python 新手。我想用 C# 构建一个机器人。我可以在 dot net 中使用这个“urllib2”还是在 dot net 中有其他选择？请帮助...

大部分等效功能都在 System.Web 中命名空间:

The System.Web namespace supplies classes and interfaces that enable browser-server communication. This namespace includes the HttpRequest class, which provides extensive information about the current HTTP request; the HttpResponse class, which manages HTTP output to the client; and the HttpServerUtility class, which provides access to server-side utilities and processes. System.Web also includes classes for cookie manipulation, file transfer, exception information, and output cache control.

urlopen 的近亲是 System.Net.Webclient类:

Provides common methods for sending data to and receiving data from a resource identified by a URI.

using System;
using System.Net;
using System.IO;

public class Test
{
    public static void Main (string[] args)
    {
        if (args == null || args.Length == 0)
        {
            throw new ApplicationException ("Specify the URI of the resource to retrieve.");
        }
        WebClient client = new WebClient ();

        // Add a user agent header in case the 
        // requested URI contains a query.

        client.Headers.Add ("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

        Stream data = client.OpenRead (args[0]);
        StreamReader reader = new StreamReader (data);
        string s = reader.ReadToEnd ();
        Console.WriteLine (s);
        data.Close ();
        reader.Close ();
    }
}
