//Все вместе в перемешку - и Object, и var и dynamic - так тоже можно:
dynamic dynamicObject = new Object();
var anotherObject = dynamicObject; // What’s the type of anotherObject? The answer is: dynamic
//Remember that dynamic is in fact a static type in the C# type system, so the compiler infers this type for the anotherObject. It’s important to understand that the var keyword is just an instruction for the compiler to infer the type from the variable’s initialization expression; var is not a type.

// Action showMethod = () => testName.DisplayToWindow();
// или так: Action showMethod = delegate() { testName.DisplayToWindow();} ;
