如何使用T4从一个模板同时生成两个文件？

Question

I am having a case in which I need to generate two CSharp code files with pretty the same code but different namespace of the input and output types of the methods. In fact each file is for a specific country and the types come from country specific WSDL's.

I am writing some wrappers around the services and the logic is exactly the same but the types automatically generated from WSDL's are different. How could I reduce the coding effort and write the logic at one place and get it generated for two different sets of types?

Answer 1

or you could use the T4 Toolbox ( Old CodePlex project , New GitHub project ) and use the helpers to generate multiple files.

Or if you don't want this dependency just for this functionality, you can use the T4 file MultiOutput.tt ( Archived version )
