阅读了一些帖子并尝试了一些事情。释放物体后,我仍然无法正常关闭。
我执行以下操作: Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
if (xlApp == null)
{
//MessageBox.Show("Excel is not properly installed!!");
return;
}
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
if (!System.IO.File.Exists("file.xlsx"))
{
xlWorkBook = xlApp.Workbooks.Add(misValue);
}
else
{
xlWorkBook = xlApp.Workbooks.Open("file.xlsx", 0, false, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", true, false, 0, true, 1, 0);
}
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet.Name = "Sheet Name";
然后关闭excel并摆脱对象:
xlApp.DisplayAlerts = false;
xlWorkBook.SaveAs("file.xlsx");
xlWorkBook.Close(true, "file.xlsx", misValue);
xlApp.Application.Quit();
xlApp.Quit();
Marshal.ReleaseComObject(xlWorkSheet);
Marshal.ReleaseComObject(xlWorkBook);
Marshal.ReleaseComObject(xlApp);
xlApp = null;
即使我这样做,我仍然在任务管理器中看到excel.exe。有人可以帮助我解决我在这里做错了什么。我真的很感激。

这是我用来杀死进程的内容。它有效,但如果有人有一个更优雅的解决方案,我也很高兴知道!
private void releaseObject(object obj)
{
try
{
Marshal.ReleaseComObject(obj);
obj = null;
var process = System.Diagnostics.Process.GetProcessesByName("Excel");
foreach (var p in process)
{
if (!string.IsNullOrEmpty(p.ProcessName))
{
try
{
p.Kill();
}
catch { }
}
}
}
catch (Exception ex)
{
obj = null;
MessageBox.Show("Unable to release the Excel Object " + ex.ToString());
}
finally
{
GC.Collect();
GC.WaitForPendingFinalizers();
}
}
在每个对象上调用它
releaseObject(worksheet);
releaseObject(workbook);
releaseObject(xlapplication);
