c#调用Httpget请求

在C#中调用HttpGet请求可以使用以下代码示例：

// 引用System.Net命名空间
using System.Net;

public string HttpGet(string url)
{
    // 创建WebRequest对象
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "GET";
    
    // 设置请求头部
    request.ContentType = "text/html, application/xhtml+xml, */*";

    // 发送请求并获取响应
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    Stream rs = response.GetResponseStream();
    
    // 读取响应数据
    StreamReader sr = new StreamReader(rs, Encoding.UTF8);
    string result = sr.ReadToEnd();
    
    // 关闭StreamReader和Stream
    sr.Close();
    rs.Close();
    
    // 返回响应数据
    return result;
}

以上代码是一个简单的C#函数，用于发起一个HttpGet请求，并返回响应数据。你可以将需要发送的URL作为参数传递给该函数，它将返回一个包含响应数据的字符串。这个函数使用了System.Net命名空间中的相关类和方法来发送和接收Http请求。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
