Call non-static method from static method c# [duplicate]

Answer 1

In the code provided you don't call non stati method in static one, but you call instance public method of another class, this is different story.

So in your case I would suggest write something like:

static void Data2(Foo foo).

Regards.

Answer 2

You will always need an instance to call an instance method. It is possible to have a delegate that points to a method on an instance - but then you still have an instance that are being used in the call, just indirectly.

Answer 3

You can do other clever things, but the reality is that along the way somewhere you have to create or access an instance of the non-static object. You could pass a delgate into the method, that refers to an instance of the method ( rather, a method on an instance of the non-static object ), but that would have had to be created outside your code.

Answer 4

This way like you did it can be called a non-static method from the static method. To call a non-static method from a static method, you have to create an new reference of the class in which the non-static method is in. So your Data1 method is in Foo class, you have to create a new referenc (Foo foo = new Foo()) to be allowed to go out of static method.

Answer 5

Yes, you can call a non-static method from anywhere using a delegate, but you need the instance of the class to create the delegate, so that the instance is available when the method is called.

Answer 6

To call a non static method you need an instance of the object - there is no way around that.
