asp.net生成静态页面

public static void GetHtml(string url,string savepath)//url参数为将要生成的那个动态页面的地址，savepath为要存放地址
{
string Result;
WebResponse MyResponse;
WebRequest MyRequest = System.Net.HttpWebRequest.Create(url);
MyResponse = MyRequest.GetResponse();
using (StreamReader MyReader = new StreamReader(MyResponse.GetResponseStream(), System.Text.Encoding.GetEncoding("utf-8")))//这里根据网站的编码格式而定
{
Result = MyReader.ReadToEnd();
MyReader.Close();
}
FileStream fs = new FileStream(savepath, FileMode.Create, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.GetEncoding("utf-8"));
sw.WriteLine(Result);
sw.Close();
fs.Close();
}
