使用Microsoft.Office.Interop.Excel.dll
导致以下错误:的Microsoft.Office.Interop.Excel未注册DLL
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll
Additional information: Retrieving the COM class factory for component with CLSID {00020819-0000-0000-C000-000000000046} failed due to the following error: 80040154 Klasse nicht registriert (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
错误在此代码的第四行occures:
using EX = Microsoft.Office.Interop.Excel;
private void LoopBANFDokumenteLibrary(System.Uri Link)
{
EX.Application MSExcel = new EX.Application();
EX.Workbook WB = MSExcel.Workbooks.Add(new EX.Workbook()); //ERROR: Exception thrown
EX.Worksheet WS = WB.Worksheets.Add(new EX.Worksheet());
/*...and further code...*/
}
若干年前,我每天都使用这个Interop.Excel.DLL,并且从来没有遇到过这个问题。打开REGEDIT.EXE,该dll被注册,你可以在这个截图中看到:
有谁有一个想法,什么是错?
的问候,并感谢您, 扬
