需要当前Request.Url的类型的对象绑定

using System;
using System.Web;

public class MyPage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        HttpRequest request = HttpContext.Current.Request;
        Uri url = request.Url;

        // 获取URL的各个部分
        string scheme = url.Scheme;         // 协议（如http、https）
        string host = url.Host;             // 主机名
        int port = url.Port;                // 端口号
        string path = url.AbsolutePath;     // 路径
        string query = url.Query;           // 查询字符串

        // 输出URL信息
        Response.Write("Scheme: " + scheme + "<br>");
        Response.Write("Host: " + host + "<br>");
        Response.Write("Port: " + port + "<br>");
        Response.Write("Path: " + path + "<br>");
        Response.Write("Query: " + query + "<br>");
    }
}
