Updated: May 30, 2016 11:39:15 Author: Qin Feng

This article mainly introduces the use of WebClient to download pictures asynchronously and display them on GridView. Friends who need it can refer to it.

private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
  ////Use WebClient to download pictures  using (WebClient wc = new WebClient())
  {
    /////WebClient response event binding     += new DownloadDataCompletedEventHandler(wc_DownloadDataCompleted);

    //// Start asynchronous download, please specify the image URL path according to the actual situation    //// At the same time, the line number of the current line of DataGridView is passed, which is used to specify the CELL of the picture display    (new Uri(this.[].Cells[1].()),
      );
  }
}


void wc_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
{
  //// If there is no error in the download process and it is not cancelled in the middle  if ( == null &amp;&amp; !)
  {
    ////// Display the image in the corresponding specified cell, which is the incoming    //// It's the download result    this.[(int)].Cells["src"].Value = ;
    // this.[(int)].Cells["test"].Value = GetImage("1");
  }
}

The above are some code snippets that display asynchronous downloading pictures. I hope you can give you a reference and I hope you can support me more.
