Mimicking C# array initializer behaviour using Reflection

Question

Using ILDasm to reverse engineer some C# code, I found out that the compiler uses the System.Runtime.CompilerServices.RuntimeHelper.InitializeArraymethod to initialize arrays that contain several constant values of primitive types.

Looks like it creates a special structure for each array size in bytes and marks it with [StructLayout] attribute. This is pretty straightforward. But then there is a field of that type that contains the actual data. How do I create a field like that in terms of Reflection.Emit and fill it with arbitrary bytes?

I think you use ModuleBuilder.DefineInitializedData for that.
