C#.net implements the method of downloading files from the internet in Winform

This article describes the method of C#.net to download files from the internet in Winform. Share it for your reference. The details are as follows:

I made a general software automatic upgrade program myself, where I need to download files from the given url to the local area and share them.

/// &lt;summary&gt;
/// Download the file/// &lt;/summary&gt;
/// <param name="URL">Download file address</param>/// <param name="Filename">Save as (full path) after downloading</param>private bool DownloadFile(string URL, string filename)
{
  try
  {
     Myrq = ()(URL);
     myrp = ()();
     st = ();
     so = new (filename, );
    byte[] by = new byte[1024];
    int osize = (by, 0, (int));
    while (osize &gt; 0)
    {
      (by, 0, osize);
      osize = (by, 0, (int));
    }
    ();
    ();
    ();
    ();
    return true;
  }
  catch ( e)
  {
    writeLogFile(, true);
    return false;
  }
}

I hope this article will be helpful to everyone's C# programming.
