当我们在调试模式下执行时，我的窗口形式应用于stoped工作 [英] My windowform applicatioin stoped working when we execute in debugging mode

问题描述

当我在调试模式下使用C＃打开时，应用程序停止工作＃

一张图像是



我尝试过的方法：

  private  < span class =code-keyword> void  Export（）
 {
 SaveFileDialog saveDialog =  new  SaveFileDialog（）; 
 saveDialog.Filter =   Excel文件（* .xlsx）| * .xlsx |所有文件（*。 。*）| *。*; 
 saveDialog.FilterIndex =  2 ; 
 
  if （saveDialog.ShowDialog（）== System.Windows.Forms.DialogResult.OK）
 {
 xlWorkBook.SaveAs（saveDialog.FileName，Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal，misValue，misValue，misValue，misValue，Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive，misValue，misValue，misValue，misValue，misValue） ; 
 StripStatusLabel.Visible =  true ; 
 StripStatusLabel.Image = Image.FromFile（ @  \\90.0.0.8\d\ Nouman's Development\SizaPayRoll For Backup\backup\SizaPayRoll\icons\images（3）.jpg）; 
 StripStatusLabel.ForeColor = Color.Green; 
 StripStatusLabel.Text =  增量导出成功excel ...; 
 xlWorkBook.Close（ true ，misValue，misValue）; 
 xlApp.Quit（）; 
 releaseObject（xlWorkSheet）; 
 releaseObject（xlWorkBook）; 
 releaseObject（xlApp）; 
} 
  else   if （saveDialog.ShowDialog（）== System.Windows .Forms.DialogResult.Cancel）
 {
 
} 
} 
  private   void  releaseObject（ object  obj）
 {
  try  
 {
 System.Runtime.InteropServices.Marshal.ReleaseComObject（obj）; 
 obj =  null ; 
} 
  catch （例外情况）
 {
 obj =  null ; 
 MessageBox.Show（ 在发布对象时发生异常 + ex.ToString（）） ; 
} 
 最后 
 {
 GC.Collect（）; 
} 
} 

解决方案

我只能假设......但我认为你应该改变你的代码这：

  private   void 导出（）
 {
 SaveFileDialog saveDialog =  new  SaveFileDialog（）; 
 saveDialog.Filter =   Excel文件（* .xlsx）| * .xlsx |所有文件（*。 。*）| *。*; 
 saveDialog.FilterIndex =  2 ; 
 DialogResult myResult = saveDialog.ShowDialog;  //  <  - 此处更改!!!  
 
  if （myResult == System.Windows.Forms.DialogResult.OK） //  <  - 这里的变化!!!  
 {
 xlWorkBook.SaveAs（saveDialog.FileName，Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal，misValue，misValue，misValue，misValue， Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive，misValue，misValue，misValue，misValue，misValue）; 
 StripStatusLabel.Visible =  true ; 
 StripStatusLabel.Image = Image.FromFile（ @  \\90.0.0.8\d\ Nouman's Development\SizaPayRoll For Backup\backup\SizaPayRoll\icons\images（3）.jpg）; 
 StripStatusLabel.ForeColor = Color.Green; 
 StripStatusLabel.Text =  增量导出成功excel ...; 
 xlWorkBook.Close（ true ，misValue，misValue）; 
 xlApp.Quit（）; 
 releaseObject（xlWorkSheet）; 
 releaseObject（xlWorkBook）; 
 releaseObject（xlApp）; 
} 
  else   if （myResult == System.Windows.Forms.DialogResult .Cancel） //  <  - 此处更改!!!  
 {
 
} 
} 

...因为如果你从SaveFileDialog获得一个DialogResult，SaveFileDialog就不再存在...



请试一试......

application stopped working when i open in debugging mode using C#

What I have tried:

private void Export()
{ 
 SaveFileDialog saveDialog = new SaveFileDialog();
            saveDialog.Filter = "Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*";
            saveDialog.FilterIndex = 2;

            if (saveDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                xlWorkBook.SaveAs(saveDialog.FileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
                StripStatusLabel.Visible = true;
                StripStatusLabel.Image = Image.FromFile(@"\\90.0.0.8\d\Nouman's Development\SizaPayRoll For Backup\backup\SizaPayRoll\icons\images (3).jpg");
                StripStatusLabel.ForeColor = Color.Green;
                StripStatusLabel.Text = "Increment export to excel successfully...";
                xlWorkBook.Close(true, misValue, misValue);
                xlApp.Quit();
                releaseObject(xlWorkSheet);
                releaseObject(xlWorkBook);
                releaseObject(xlApp);
            }
            else if (saveDialog.ShowDialog() == System.Windows.Forms.DialogResult.Cancel)
            {

            }
}
 private void releaseObject(object obj)
        {
            try
            {
                System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
                obj = null;
            }
            catch (Exception ex)
            {
                obj = null;
                MessageBox.Show("Exception Occured while releasing object " + ex.ToString());
            }
            finally
            {
                GC.Collect();
            }
        }

解决方案

I only can suppose ... but I think you should change your code like this :

private void Export()
{ 
 SaveFileDialog saveDialog = new SaveFileDialog();
            saveDialog.Filter = "Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*";
            saveDialog.FilterIndex = 2;
            DialogResult myResult = saveDialog.ShowDialog ;  // <- Changes here !!!

            if (myResult == System.Windows.Forms.DialogResult.OK)  // <- Changes here !!!
            {
                xlWorkBook.SaveAs(saveDialog.FileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
                StripStatusLabel.Visible = true;
                StripStatusLabel.Image = Image.FromFile(@"\\90.0.0.8\d\Nouman's Development\SizaPayRoll For Backup\backup\SizaPayRoll\icons\images (3).jpg");
                StripStatusLabel.ForeColor = Color.Green;
                StripStatusLabel.Text = "Increment export to excel successfully...";
                xlWorkBook.Close(true, misValue, misValue);
                xlApp.Quit();
                releaseObject(xlWorkSheet);
                releaseObject(xlWorkBook);
                releaseObject(xlApp);
            }
            else if (myResult == System.Windows.Forms.DialogResult.Cancel)  // <- Changes here !!!
            {

            }
}

... because if you get a DialogResult from the SaveFileDialog the SaveFileDialog is no more existing ...

Please try it ...
