在调试时我得到了这样的错误尝试读取或写入受保护的内存。这通常表明其他内存已损坏。

下面的错误代码行适用于捕获屏幕并执行 ocr。但是动态地（意味着具有特定时间限制的多个时间捕获窗口）更改窗口捕获并执行 ocr 会给出错误。

private void OCRImplementationall()
        {
            MODI.Document md = new MODI.Document();

            Cursor = Cursors.WaitCursor;
            string Name = AppDomain.CurrentDomain.BaseDirectory + @"PT INFO.JPG";
            try
            {
                int fflag = 0;
                CheckForIllegalCrossThreadCalls = false;
                md.Create(Name);
                md.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true);
                string strText = String.Empty;

                MODI.Image image = (MODI.Image)md.Images[0];
                MODI.Layout layout = image.Layout;
                string[] splvalues = layout.Text.Trim().Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
                //for (int i = 0; i < layout.Words.Count; i++)
                int i = 0;
                foreach (string val in splvalues)
                {}}
  catch (Exception ex)
            {
               //ExceptionHelper exlne = new ExceptionHelper();

                LogFile(ex.Message, "OCRImplementationall", "PT INFO Image Error", ExceptionHelper.LineNumber(ex), this.FindForm().Name);


                //MessageBox.Show(ex.Message);
            }
            finally
            {
                Cursor = Cursors.Default;
            }
}

我可以知道我在这些方面提出的问题吗
