Interop Excel没有关闭流程

Question

我已经在这个问题上苦苦挣扎了几天,我已经进行了研究并应用了我在各种论坛上发现的所有建议,但我仍然无法解决它.

我的问题是excel使用互操作库,我有一个excel文件用作模板,所以我打开它并保存在一个新名称的新位置.一切都很好,除了Excel进程在创建和关闭文件后继续运行.

这是我的代码

protected string CreateExcel(string strProjectID, string strFileMapPath)
{
    string strCurrentDir = HttpContext.Current.Server.MapPath("~/Reports/Templates/");
    string strFile = "Not_Created";

    Application oXL;
    Workbook oWB;        

    oXL = new Application();
    oXL.Visible = false;

    Workbooks wbks = oXL.Workbooks;
    //opening template file
    oWB = wbks.Open(strFileMapPath);        

    oXL.Visible = false;
    oXL.UserControl = false;
    strFile = strProjectID + "_" + DateTime.Now.Ticks.ToString() + ".xlsx";
    //Saving file with new name
   oWB.SaveAs(strCurrentDir + strFile, XlFileFormat.xlWorkbookDefault, null, null,    false, false, XlSaveAsAccessMode.xlExclusive, false, false, null, null);

    oWB.Close(false, strCurrentDir + strFile, Type.Missing);

    wbks.Close();

    oXL.Quit();


    System.Runtime.InteropServices.Marshal.ReleaseComObject(oXL);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(wbks);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(oWB);


    oWB = null;
    oXL = null;
    wbks = null;
    GC.Collect();

    return strFile;
}

如您所见,我正在关闭并释放所有对象,但应用程序不会退出.

我正在使用IIS7在32位的Windows Server 2008(生产)和Windows 7(开发)中进行测试.

Answer 1

尝试

Process excelProcess = Process.GetProcessesByName("EXCEL")[0];
if (!excelProcess.CloseMainWindow())
{
 excelProcess.Kill();
}

Answer 2

oWB.Close(false, strCurrentDir + strFile, Type.Missing);
oWB.Dispose();
wbks.Close();
wbks.Dispose();
oXL.Quit();
oXL.Dispose();


System.Runtime.InteropServices.Marshal.ReleaseComObject(oXL);
System.Runtime.InteropServices.Marshal.ReleaseComObject(wbks);
System.Runtime.InteropServices.Marshal.ReleaseComObject(oWB);
