如何在C＃中表示Golang的界面{}？

I'm trying to convert some Go code to C#. In Go there is, in example:

type MyType interface{}

Is this something like object in C# or MyType<T>?

In Go code, there is an array of these interfaces and every one of them returns a function with different arguments.

I can return List of Funcs in C# but then the dynamic arguments are the problem.

I'm having problems about representing this in C#. Need some guidance to find the right path.
