There are different office version, different com type libraries for managing them.
Could anyone tell me how should i write the code to operate on different Excel version? What about PIA for office, should I include them all with the project?
How to solve the problem of office multiversioning?
1) take advantage of the dynamic binding
2) stick with late binding
and your code will work on any version.
// work with any version
Type wordType = Type.GetTypeFromProgId( "Word.Application" );
dynamic wordApp = Activator.CreateInstance( wordType );
// late binding + dynamics - always works
wordApp.Visible = true;
