How would I go about capturing one frame from a feed of video from a webcam or video capture card in C#? I want to display the live feed and have a method that takes one frame and saves it to a remote server either via FTP or over a shared network path.

If you are able to streaming live video, then you can capture the live video stream just click on button by this code:
private Capture capture = null;
private void btnStart_Click(object sender, System.EventArgs e)
{
try
{
if ( capture == null )
throw new ApplicationException( "Please select a video and/or audio device." );
if ( !capture.Cued )
capture.Filename = txtFilename.Text;
capture.Start();
btnCue.Enabled = false;
btnStart.Enabled = false;
}
catch (Exception ex)
{
MessageBox.Show( ex.Message + "\n\n" + ex.ToString() );
}
}

You could use OpenCV. If you search on StackOverflow you'll find a lot of source on how to do that.
There's even .NET wrappers for OpenCV like opencvdotnet and Emgu CV.
You will probably end up using a few functions from the library, such as cvCaptureFromCAM() and cvQueryFrame().
