private static void GetHtmlFile()
{
//using System.Net;
//using System.Windows.Forms; string remoteUri = @"http://www.baidu.com/img/";
string fileName = "logo.gif", myStringWebResource = null;
// Create a new WebClient instance.
WebClient myWebClient = new WebClient();
// Concatenate the domain with the Web resource filename.
myStringWebResource = remoteUri + fileName;
Console.WriteLine("Downloading File \"{0}\" from \"{1}\" .......\n\n", fileName, myStringWebResource);
// Download the Web resource and save it into the current filesystem folder.
myWebClient.DownloadFile(myStringWebResource,fileName);        
Console.WriteLine("Successfully Downloaded File \"{0}\" from \"{1}\"", fileName, myStringWebResource);
Console.WriteLine("\nDownloaded file saved in the following file system folder:\n\t" + Application.StartupPath);
Console.ReadLine(); }试试这个

如果没有特殊需要..就用webclient吧..这东西快.出现错误一般..查看一下IE下载时的数据包.. 对好了.一般就OK
