Question

給定一個URL，下載該網頁內容的最有效的代碼是什麼？我只考慮HTML，而不是關聯的圖像，JS和CSS。

Answer 1

public static void DownloadFile(string remoteFilename, string localFilename) 
{ 
    WebClient client = new WebClient(); 
    client.DownloadFile(remoteFilename, localFilename); 
} 

Answer 2

System.Net.WebClient

從MSDN：

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(); 
    } 
}

使用來自System.Net WebClient類;在.NET 2.0和更高版本上。

Client.DownloadFile("http://mysite.com/myfile.txt", " C:\myfile.txt"); 

Answer 4

這裏是我的答案，這需要一個URL，並返回一個字符串

public static string downloadWebPage(string theURL) 
    { 
     //### download a web page to a string 
     WebClient client = new WebClient(); 

     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(theURL); 
     StreamReader reader = new StreamReader(data); 
     string s = reader.ReadToEnd(); 
     return s; 
    } 

Answer 5

WebClient.DownloadString

public static void DownloadString (string address) 
{ 
    WebClient client = new WebClient(); 
    string reply = client.DownloadString (address); 

    Console.WriteLine (reply); 
}
