There are 2 purposes of explicit implementation of Interface:
First, it is used to avoid name collision between interface methods. That is if you are going to create a class library, there may be a chance to use the same name in several places. At that time "explicit" implementation comes as a rescue.
Secondly, You cannot access that implemented method through the object of the class directly. Instead you typecast it as Interface reference then you can access it. This is because, the C# complier, unable to determine which one the user want to call.

Daily interview Question #9: what is the purpose of ref and out parameters in C#?

Ref keyword is used to send the particular parameter as a reference to the function or subroutine.
In some cases we may want to return value from the function but we don't want to use that variable within the function. We just get back some value, that's all. In these kind of scenarios we may go with 'out' parameter.
The main difference between the two is, before passing ref parameter we must initialize the particular variable. But this kind of initialization is not necessary with 'out' parameter.
