Reflection with T4 get assemblies

问题

I want to get all of class in the specific assembly this is my code

 var assembly=Assembly.GetExecutingAssembly();

 var assemblies = assembly.GetTypes().Where(t => String.Equals(t.Namespace, "RepoLib.Rts.Web.Plugins.Profiler.Models", StringComparison.Ordinal)).ToArray();

when c# code all thing is ok and i get my assemblies but when write in t4 file i dont have any error but my assemblies count is.

In a T4 template the executing assembly is not yours but one from the T4 engine.

To access types from your assemblies, you have to perform the following steps:

1. Add a reference to your assembly to the template. Put that at the top of it:

   <#@ assembly name="$(SolutionDir)<Project>\bin\Debug\<Project>.dll" #>
   

2. Import the namespace of your assembly. Put that somewhere below the previous line:

   <#@ import namespace="<Project>.<Namespace>" #>
   

3. To access the types in this assembly, pick one of them and get the assembly from it:

   var assembly = typeof(<Type in assembly>).Assembly;
   var types = assembly.GetTypes()
                       .Where(t => String.Equals(
                           t.Namespace,
                           "RepoLib.Rts.Web.Plugins.Profiler.Models",
                           StringComparison.Ordinal))
                       .ToArray();
