当我使用一个在行上有断点的调试程序时：

pictureBox1.Invoke(new Action(() => pictureBox1.Image = bitmap));

当它试图执行这一行时，它会抛出异常错误。当我把鼠标放在这一行的位图上时，我没有看到任何问题。
我试着改变pictureBox1的大小和大小模式，但它没有改变任何东西。
异常消息：

System.ArgumentException
  HResult=0x80070057
  Message=Parameter is not valid.

方法：

private void DisplayFrameInPictureBox(Mat frame)
{
    // Create a copy of the Mat frame
    using (var frameCopy = new Mat())
    {
        frame.CopyTo(frameCopy);

        // Convert Mat copy to Bitmap
        using (var bitmap = frameCopy.ToBitmap())
        {
            // Display the bitmap in the PictureBox
            if (pictureBox1.InvokeRequired)
            {
                pictureBox1.Invoke(new Action(() => pictureBox1.Image = bitmap));
            }
            else
            {
                pictureBox1.Image = bitmap;
            }
        }
    }
}
