When do you use the “this” keyword? [closed]

Answer 1

Another somewhat rare use for the this keyword is when you need to invoke an explicit interface implementation from within the implementing class. Here's a contrived example:

class Example : ICloneable
{
    private void CallClone()
    {
        object clone = ((ICloneable)this).Clone();
    }

    object ICloneable.Clone()
    {
        throw new NotImplementedException();
    }
}
