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

Answer 1

This is one method for calling a non-static method via a delegate. Note that it is a two-step process, since to call a non-static method, you absolutely need an instance of the class. I would also note that there is almost certainly a better way to do what you want to do, since needing to call a non-static method from a static method despite not wanting to use an object instance makes it sound like the non-static method should be static.

public class MyClass
{
    private static Action NonStaticDelegate;

    public void NonStaticMethod()
    {
        Console.WriteLine("Non-Static!");
    }

    public static void CaptureDelegate()
    {
        MyClass temp = new MyClass();
        MyClass.NonStaticDelegate = new Action(temp.NonStaticMethod);
    }

    public static void RunNonStaticMethod()
    {
        if (MyClass.NonStaticDelegate != null)
        {
            // This will run the non-static method.
            //  Note that you still needed to create an instance beforehand
            MyClass.NonStaticDelegate();
        }
    }
}
