objExcelBook = objExcelApp.Workbooks.Add()
        objExcelSheet = objExcelApp.Worksheets.Add()
        Dim filename As String = Left(Server.MapPath(Request.ApplicationPath), Len(Server.MapPath(Request.ApplicationPath)) - 7) & "\bc_web\downloadfile\gongsi" & Left(Trim(CStr(Now())), 10) & ".xls"
        BindGrid() '绑定数据
        ' objExcelSheet.Columns("S:S").Select()
        '  objExcelApp.Selection.NumberFormatLocal = "@"        ' objExcelSheet.Columns("AH:AH").Select()
        'objExcelApp.Selection.NumberFormatLocal = "@"        For j = 1 To cds.Tables("gskh").Columns.Count - 1
            objExcelApp.Cells(1, j) = cds.Tables("gskh").Columns(j).ColumnName
        Next j        For i = 1 To cds.Tables("gskh").Rows.Count
            For j = 1 To cds.Tables("gskh").Columns.Count - 1
                objExcelApp.Cells(i + 1, j) = cds.Tables("gskh").Rows(i - 1).Item(j)
            Next j
        Next i
        objExcelBook.SaveAs(filename)
        objExcelBook.Close()
        objExcelApp.Quit()
        System.Runtime.InteropServices.Marshal.ReleaseComObject(objExcelSheet)
        System.Runtime.InteropServices.Marshal.ReleaseComObject(objExcelBook)
        System.Runtime.InteropServices.Marshal.ReleaseComObject(objExcelApp)
        objExcelApp = Nothing
        objExcelBook = Nothing
        objExcelSheet = Nothing
        System.GC.Collect()加了 ' objExcelSheet.Columns("S:S").Select()
        '  objExcelApp.Selection.NumberFormatLocal = "@"        ' objExcelSheet.Columns("AH:AH").Select()
        'objExcelApp.Selection.NumberFormatLocal = "@"
后就QUIT不了EXCEL,运行后那EXCEL进程仍存在,用了
 Public Sub KillExcel() '用来终止EXCEL进程
        Dim pProcess() As System.Diagnostics.Process
        pProcess = GetProcesses()
        Dim i As Integer
        For i = 0 To pProcess.Length() - 1
            If (pProcess(i).ProcessName = "EXCEL.EXE") Then
                pProcess(i).Kill() '关闭进程
                Exit For
            End If
        Next
    End Sub
又出现拒绝访问,救命啊

    在论坛中经常看到问如何结束Excel进程的帖子,很多人给出
    的方法是先得到系统进程列表,然后和“Excel”匹配,是Excel
    的进程就杀死,我个人认为这个方法是不可行的,如果软件用这种方法
    杀死自己启动的进程,应该算是Bug(有可能将用户Excel进程杀掉)。
        我在网上找到了另一种杀死Excel 进程的方法,如下:
    System.Runtime.InteropServices.Marshal.ReleaseComObject(worksheets);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(worksheet);
    ...
    System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(range);
    worksheets=null;
    worksheet=null;
    ...
    excelApp=null;
    range=null;把操作Excel文件用到的对象实例全部释放。 
    然后资源回收!
    GC.Collect();以上的代码最好能放在finally中,防止操作Excel文件时发生异常而执行不到!在打开任务管理器看看,excel进程是不是已经不在了!
