public void ReadWebFile(string url,string fileName)

WebClient client = new WebClient();
client.Headers.Add("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
client.Headers.Add("UserAgent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

Answer 2

void SetType()
{
string pathHtm = Application.StartupPath + @"\1.htm";//路径
if (File.Exists(pathHtm))
File.Delete(pathHtm);
FileStream fs = new FileStream(pathHtm, FileMode.Create);
string picType = "";
StringBuilder sb = new StringBuilder();
sb.AppendFormat("网页文件", picType);
byte[] data = new UTF8Encoding().GetBytes(sb.ToString());
fs.Write(data, 0, data.Length);
fs.Flush();
fs.Close();
}
