Question

我正在尝试使用SSIS打开Excel文件并在将数据导入SQL Server之前刷新数据。我的dtsx软件包在尝试打开Excel文件的代码行上失败。

代码很简单，取自here。

这是我正在使用的代码：

public void Main()
{
    // TODO: Add your code here
    Dts.TaskResult = (int)ScriptResults.Success;

    Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
    Microsoft.Office.Interop.Excel.Workbook wb;

    wb = excel.Workbooks.Open(@"C:\Test.xlsx",0, false, null, null, null, true, null, null, null, null, null, null, null, null);
    //wb.RefreshAll();
    //wb.Save();
    //wb.Close(null, null, null);
    excel.Quit();

    System.Runtime.InteropServices.Marshal.ReleaseComObject(excel);


}

错误消息如下：

Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC

   at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript()

我目前正在使用以下配置处理我的测试机器：

Visual Studio 2008 BIDS
Office 2010
Office 2010 PIA

有没有人对如何使这项工作有任何建议？

使用Type.Missing代替null。并且在每个变量之前还有ref。见http://msdn.microsoft.com/en-us/library/system.type.missing(v=VS.90).aspx
