The code has some bugs. It is supposed to raise an event, whenever the File is downloaded

delegate void DownloadCompeteHandler(int perc);

public class FileDownloader

{

protected string resourceUrl;

protected string resourceSavePath;

event DownloadCompeteHandler DownLoadComplete;

public FileDownloader(string url,string savepath)

{

this.resourceUrl = url;

this. resourceSavePath = savepath;

}

public void DownLoadResource()

{

for (int i = 1; i <= 4; i++)

{

for (int j = 1; i <= 10000; i++);

OnDownLoadComplete(i * 25);

}

}

protected void OnDownLoadComplete( )

{

if (DownLoadComplete == null)

DownLoadComplete( );

}

}

public static void Main(string[] args)

{

FileDownloader fd =

new FileDownloader("http://www.microsoft.com/vstudio/expressv10.zip", "d:\\setups");

fd.DownLoadComplete += new Handler();

fd.DownLoadResource();

Console.ReadKey();

}

static void fd_DownLoadComplete(int perc)

{

Console.SetCursorPosition(10, 10);

Console.Write("Downloading {0} Percent Complete", perc);

}
