好的，首先我只是想说我已经尝试了多个教程来解决这个错误和众多网站，我已经搜索了这个论坛的潜在解决方案，但无济于事。我使用的代码几乎与我在互联网上找到的代码相同，运行代码时没有语法错误。所以我得出结论，我有一个参考或链接问题。
namespace Video_Capture
{
public partial class CameraCapture : Form
{
//Variable Declaration
private Capture capture; //takes images from camera as image frame
private bool captureInProgress; //checks if capture is executing
private void ProcessFram(object sender, EventArgs arg)
{
Image<Bgr, Byte> ImageFrame = capture.QueryFrame();
CamImageBox.Image = ImageFrame;
}
public CameraCapture()
{
InitializeComponent();
}
private void btnStart_Click(object sender, EventArgs e)
{
#region if capture is not created, create it now
if (capture == null)
{
try
{
capture = new Capture();
}
catch (NullReferenceException excpt)
{
MessageBox.Show(excpt.Message);
}
}
#endregion
if (capture != null)
{
if (captureInProgress)
{ //if camera is getting frames then stop the capture and set button Text
//"Start" for resuming capture
btnStart.Text = "Start!";
Application.Idle -= ProcessFram;
}
else
{
//if camera is not getting frames then start the capture and set button
//Text to "stop" for pausing capture
btnStart.Text = "Stop";
Application.Idle += ProcessFram;
}
captureInProgress = !captureInProgress;
}
}
private void ReleaseData()
{
if (capture != null)
capture.Dispose();
}
}
}
After running the code and pressing the "start" button I get this error.
