Question

how to call static method inside non static method in c# ?

Interviewer gave me scenario :

class class1
{

    pub         


        

Answer 1

if you call the method in the some class you just call it like this

    public void method2()
    {
        method1();  

    }

but if it should been called from another class you have to precede it with the name of the class

public void method2()
        {
            class1.method1();  

        }
