Overloading

Overloading is when you have multiple methods in the same scope, with the same name but different signatures.

//Overloading
public class test
{
    public void getStuff(int id)
    {}
    public void getStuff(string name)
    {}
}

Overriding

Overriding is a principle that allows you to change the functionality of a method in a child class.

//Overriding
public class test
{
        public virtual void getStuff(int id)
        {
            //Get stuff default location
        }
}

public class test2 : test
{
        public override void getStuff(int id)
        {
            //base.getStuff(id);
            //or - Get stuff new location
        }
}
