以Odata作为源代码，在Excel工作簿中以编程方式创build数据透视表

我正在尝试使用C＃在Excel工作簿中创build数据透视表。 来源是Odata供稿url。 我写了下面的代码：

string connectionString = @"DATAFEED;Data Source=" + odataURL + ";Namespaces to Include=*;Max Received Message Size=4398046511104;Integrated Security=Basic;User ID=" + "xyz" + ";Password=" + "bvby" + ";Persist Security Info=true;Base Url=" + odataURL; Excel.PivotCache pivotCache = app.ActiveWorkbook.PivotCaches().Add(Excel.XlPivotTableSourceType.xlExternal, Type.Missing); pivotCache.Connection = connectionString; 

当我做pivotCache.Connection时抛出下面的exception：

 System.Runtime.InteropServices.COMException was caught HResult=-2146827284 Message=Exception from HRESULT: 0x800A03EC Source="" ErrorCode=-2146827284 

堆栈跟踪：
