C#动态生成静态页面

　　.NET的WebRequest类提供了许多WEB请求功能，方便了Windows Form和Web Form对WEB的交互操作，加上Stream的操，可以很方便的通过URL将动态页面生成静态页面，并保存在本地或服务器上，因为是通过URL请求，所以不存在语言和编码的限制，同时，可以适用于Windows Form和Web Form，下面柯男写了一个简单的类，来完成一些基本操作。

StaticPage.cs
using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Net;
using System.IO;
/// <summary>
///URL动态保存静态页面
/// </summary>
public class StaticPage
{
    private string _url="";
    private WebRequest request;
    private WebResponse response;
 public StaticPage()
 {
  
 }
    public StaticPage(string url)
    {
        _url = url;
    }
    public string Url
    {
        get
        {
            return _url;
        }
        set
        {
            _url = value;
        }
    }
    public bool Save(string FilePath)
    {
        bool _isOk = false;
        if(_url!="")
        {
            request = WebRequest.Create(_url);
            response=request.GetResponse();
            if(File.Exists(FilePath))
            {
                File.Delete(FilePath);
            }
            StreamReader reader = new StreamReader(response.GetResponseStream(),System.Text.Encoding.Default);
            StreamWriter write = new StreamWriter(FilePath,false, System.Text.Encoding.Default);
            write.Write(reader.ReadToEnd());
            write.Flush();
            write.Close();
            write = null;
            _isOk = true;
        }
        return _isOk;
    }
}
