所有

我有以下代码可以正常工作，但是我想保存（覆盖更改）而不是SaveAs。据我所知，Close（True）应该实现这一点，但它仍然为用户提供了一个save选项。：S

非常感谢以下任何帮助/建议。

            Microsoft.Office.Interop.Excel.Workbook myWorkBook;
            Microsoft.Office.Interop.Excel.Worksheet myWorkSheet;
            Microsoft.Office.Interop.Excel.Range range;
            myApp = new Microsoft.Office.Interop.Excel.Application();
            myWorkBook = myApp.Workbooks.Open(WorkbookName2, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
            myWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)myWorkBook.Worksheets.get_Item(1);
            range = (Microsoft.Office.Interop.Excel.Range)myWorkSheet.Application.Rows[1, Type.Missing];
            range.Select();
            range.Delete(Microsoft.Office.Interop.Excel.XlDirection.xlUp);
            myWorkBook.Close(true);
            myApp.Quit();
        }
    }
}

Answer 1

您可以暂时“静音”Excel

myApp.DisplayAlerts = false;
myWorkBook.Close(true);
myApp.DisplayAlerts = true;

那么你应该考虑发布你的COM对象

示例：

if (obj != null && Marshal.IsComObject(obj))
{
    Marshal.ReleaseComObject(obj);
}

Answer 2

所以你可以这样做来阻止DisplayAlerts出现：

myApp.DisplayAlerts = false;

然后，如果您想通过指定文件名进行保存，则可以执行以下操作：

//specifying a file name
myWorkSheet.SaveAs(filename, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, true, false, XlSaveAsAccessMode.xlNoChange, XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing);
myWorkBook.Close(true);

或者你可以通过以下方式做到这一点：

myWorkBook.Close(SaveChanges:=True, Filename:=YourFileDirectory/FileName)

如果您只想保存存在的文件而不指定文件目录/文件名。就这样做：

myApp.DisplayAlerts = false;
myWorkBook.Save();
myWorkBook.Close(true);

使用Excel.Interop C＃保存覆盖和更改
