I want to enforce certain type initializers in an assembly to run at
startup.

foreach (Type t in Assembly.GetExecutingAssembly().GetTypes())
{
if (...some criteria...)
{
t.TypeInitializer.Invoke(type,new object[0]);
}
}

This doesn't work.

What's the simplest way to initialize a type, given its Type object?

Are you looking for
System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor() ?

Yes - though I'm not quite happy with what I see. Seems a bit
weird or low-level to use a handle. The docs state nothing about
what will happen if the type has already been run, so I think I'll
just stick with using reflection to access a static field of the classes
instead - which will do the job in my case.

But thanks for the hint anyway - I didn't figure CompilerServices would
be the place to look.
