C# codepublicbool downfile(string url,string LocalPath)
 {try
 {
   Uri u=new Uri(url);
   HttpWebRequest mRequest= (HttpWebRequest)WebRequest.Create(u);
   mRequest.Method="GET";
   mRequest.ContentType="application/x-www-form-urlencoded";

   HttpWebResponse wr= (HttpWebResponse)mRequest.GetResponse();

   Stream sIn= wr.GetResponseStream();
   FileStream fs=new FileStream(LocalPath, FileMode.Create, FileAccess.Write);long length= wr.ContentLength;long i=0;decimal j=0;while (i < length)
   {byte[] buffer=newbyte[1024];
   i+= sIn.Read(buffer,0, buffer.Length);
   fs.Write(buffer,0, buffer.Length);if((i%1024)==0)
   {
     j=Math.Round(Convert.ToDecimal((Convert.ToDouble(i)/Convert.ToDouble(length))*100),4);
     statusBar1.Text="当前下载文件大小:"+length.ToString()+"字节  当前下载大小:"+i+"字节 下载进度"+j.ToString()+"%";
   
   }else
   {
     statusBar1.Text="当前下载文件大小:"+length.ToString()+"字节  当前下载大小:"+i+"字节";
   }
   
   }

   sIn.Close();
   wr.Close();
   fs.Close();returntrue;
 }catch {returnfalse; }
 }
