无法使用SSIS打开Excel文件
我正在尝试使用SSIS打开Excel文件并在将数据导入到SQL Server之前刷新数据。 我的dtsx包在尝试打开Excel文件的代码行上失败。
代码很简单，从这里拿走。
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); } 错误消息如下所示：
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.Office.Interop.Excel.Workbooks.Open(String Filename, Object UpdateLinks, Object ReadOnly, Object Format, Object Password, Object WriteResPassword, Object IgnoreReadOnlyRecommended, Object Origin, Object Delimiter, Object Editable, Object Notify, Object Converter, Object AddToMru, Object Local, Object CorruptLoad) at ST_2177878595ee4288864728b04a894c16.csproj.ScriptMain.Main() --- End of inner exception stack trace --- at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams) at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript()
我目前正在使用以下configuration在我的testing机器上工作：
- Visual Studio 2008 BIDS
- Office 2010
- Office 2010 PIA
有没有人有任何build议，如何得到这个工作？
使用Type.Missing来代替null 。 而且还在每个variables前ref 。 请参阅http://msdn.microsoft.com/en-us/library/system.type.missing(v=VS.90).aspx
