Download a file from the web and save it with an arbitrary local file name in C#

This is actually pretty easy using a WebClient object.

First, add a "using System.Net" statement to the top of the file.

The following code shows how the program responds when you click the Download button.

private void btnDownload_Click(object sender, EventArgs e) { this.Cursor = Cursors.WaitCursor; Application.DoEvents(); try { // Make a WebClient. WebClient web_client = new WebClient(); // Download the file. web_client.DownloadFile(txtRemoteFile.Text, txtLocalFile.Text); MessageBox.Show("Done"); } catch (Exception ex) { MessageBox.Show(ex.Message, "Download Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } this.Cursor = Cursors.Default; }

The code simply creates a WebClient object and invokes its DownloadFile method passing it the remote file's URL and the destination file's name. That's all there is to it!
