            original.Image=imgOrg;
            processed.Image=imgProc;
        }

        private void playorpause_Click(object sender, EventArgs e)
        {
            if (CapturingProcess == true)
            {
                Application.Idle -= ProcessFunction;
                CapturingProcess = false;
                playorpause.Text= "Play";
            }
            else
            {

                CapturingProcess = true;
                playorpause.Text= "Pause";
            }
        }
    }
}

我尝试过的事情:

调试后，错误:

What I have tried:

After Debug, error:

"The type initializer for ''Emgu.CV.CvInvoke'' threw an exception."

.

推荐答案

，这是运行时问题，具体取决于何时发生.可能的原因可能是"Emgu"运行时不存在或无法在应用程序中运行.就像未注册的dll或不在应用程序目录中的dll或该问题的某些错误版本.

尝试检查异常的详细信息，因为通常会有一些详细的文本解释发生了什么.

it is a runtime issue, depending when it happens. A possible reason maybe that the "Emgu"-runtime isnt present or working in the app. Like not registered or dlls not in the app-directory or some wrong version like in that question The type initializer for '''' threw an exception.

Try to inspect the details of the exception, because often some detail text explains what happened.
