CustomDocuments Properties in Excel
I don't have any compile errors, but at run time I get and Invalid Cast Type.
I have tried boxing the type, but that does not work. Here is what my Code Looks like:
Microsoft.Office.Core.DocumentProperties cdp;
Microsoft.Office.Introp.Excel.Application app;
Microsoft.Office.Introp.Excel.Workbook wb;
app = new Microsoft.Office.Introp.Excel.Application();
wb = app.workbooks.open(Filename, Missing.Value ....);
cdp = (Microsoft.Office.Core.DocumentProperties)wb.CustomDocumentProperties; // Error Happens Here
foreach(Microsoft.Office.Introp.Core.DocumentProperty dp in cdp)
{
....
}
