[英]C# Interop not closing Excel process after execution
I have the following blocks of code: 我有以下代码块:
Excel.Application xlApp = new Excel.Application();
Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(this.pathToFile);
Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
Excel.Range xlRange = xlWorksheet.UsedRange;
I push the xlRange into an array using: 我使用以下命令将xlRange推入数组:
someArray = (System.Object[,])xlRange.Value2;
Afterwards I try to cleanup with: 之后,我尝试使用以下方法进行清理:
Marshal.ReleaseComObject(xlRange);
Marshal.ReleaseComObject(xlWorksheet);
xlWorkbook.Close();
Marshal.ReleaseComObject(xlWorkbook);
xlApp.Quit();
Marshal.ReleaseComObject(xlApp);
However, even with all four of the excel objects being released with Marshal
, the process stays open and prevents the file from being opened again. 但是,即使Marshal
释放了所有四个excel对象,该过程仍保持打开状态,并阻止了文件再次打开。
Any ideas as to how to properly clean up Interop
excel objects? 关于如何正确清理Interop
excel对象的任何想法?
I had a similar issue and managed to close the application following this processs; 我遇到了类似的问题,并按照以下过程设法关闭了该应用程序;
GC.Collect();
GC.WaitForPendingFinalizers();
Marshal.FinalReleaseComObject(xlRange);
Marshal.FinalReleaseComObject(xlWorksheet);
xlWorkbook.Close(false, Type.Missing, Type.Missing);
Marshal.FinalReleaseComObject(xlWorkbook);
xlApp.Quit();
Marshal.FinalReleaseComObject(xlApp);
