将PPT转换为PDF时出错

Question

I am trying to make a application which converts docx/xls/ppt to pdf.

1. Conversion of docx and xls requires Microsoft.Office.core dll
2. Conversion of ppt requires Office.dll

I successfully converted 1 and 2 separately but when i try to merge both of them ie

when i try to add both the reference (Microsoft.Office.core dll and Office.dll) together it gives me error.

so, is there any problem in adding both the dll's ?

229 error of same Kind ---- Error 1 Cannot embed interop type 'Microsoft.Office.Core.MsoBlogImageType' found in both assembly 'e:\\All Pdf\\waterMark_PDF\\PDF Merger and Protector Source Code\\PDFMerger\\obj\\Debug\\Interop.Microsoft.Office.Core.dll' and 'c:\\Program Files\\Microsoft Visual Studio 10.0\\Visual Studio Tools for Office\\PIA\\Office12\\Office.dll'. Consider setting the 'Embed Interop Types' property to false.

Note - i had changed "Embed Interop Types" property to false for both dll's.

please help.

Answer 1

Just use the specific libraries:

using Excel = Microsoft.Office.Interop.Excel;
using Word = Microsoft.Office.Interop.Word;
using Power = Microsoft.Office.Interop.PowerPoint;

They should have everything you need along with not having namespace isssues between interlocking dll's

These are found as COM references

EDIT: Also, are you using correct namespaces? If you could post some code it would be helpful.
