First thing Put on your title the language Tag [C++] or [C#] because it will be confusing..
On your question:
Set a filter to openfiledialog, the filter will receive a string like this "First Name | extention | second name | extention | etc..
Example:
openFD.Filter = "LOD files | *.lod | DTA fles | *.dta"
