How to make TT T4 template output multiple files (VS2010)-access911.net article

Problem:

The TT template feature in VS2010 is very useful, but how to define its output directory, or how to program a TT file to output multiple result files.

The Texttransformation parameter defines a namespace whose type is generatedtexttransformation or texttransformation can be successfully generated because it is never possible with a randomly generated name in the TT template.

Also need to reference C:\WINDOWS\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualStudio.TextTemplating.Interfaces.10.0\v4.0_ 10.0.0.0__b03f5f7f11d50a3a\microsoft.visualstudio.texttemplating.interfaces.10.0.dll </summary> <param name= "FileName" ></param> <param name= "Texttransformation" ></param> Public File (String fileName, Generatedtexttransformation texttransformation) Public File (String fileName, Generatedtexttransformation texttransformation) { string outputDir = null; The original code on the Internet is as follows; PropertyInfo Outputdirprop = Texttransformation.gettype ().
