C# Data Types or what are Data Types in C#

A variable holds data that has a specified type. When we declare a variable to store data in an application, we are required to choose an appropriate data type for that data to hold.

It is known that C# is a type-safe language, which means that the compiler guarantees that values that are stored in variables are always of the appropriate type.
