C# 发送Http请求 - WebClient类

WebClient位于System.Net命名空间下，通过这个类可以方便的创建Http请求并获取返回内容。

一、用法1 - DownloadData

string uri = "http://hovertree.top/";
 
WebClient wc = new WebClient();
 
Console.WriteLine("Sending an HTTP GET request to " + uri);
 
byte[] bResponse = wc.DownloadData(uri);
 
string strResponse = Encoding.ASCII.GetString(bResponse);
 
Console.WriteLine("HTTP response is: ");
 
Console.WriteLine(strResponse);
 
// 何问起

二、用法2 - OpenRead

string uri = "http://hovertree.net";
 
WebClient wc = new WebClient();
 
Console.WriteLine("Sending an HTTP GET request to " + uri);
 
Stream st = wc.OpenRead(uri);
 
StreamReader sr = new StreamReader(st);
 
string res = sr.ReadToEnd();
 
sr.Close();
 
st.Close();
 
Console.WriteLine("HTTP Response is ");
 
Console.WriteLine(res);
// 何问起
