C# Nameof Operator

C# NameOf operator is used to get name of a variable, class or method. It returns a simple string as a result.

In error prone code, it is useful to capture a method name, in which error occurred.

We can use it for logging, validating parameters, checking events etc.

Note: if we want to get fully qualified name, we can use typeof expression along with nameof operator.

Let's see an example that implements nameof operator.
