C# Generics – An Introduction
There is a reality; most of the developers confuse about C# Generics. Actually, there is no reason for that. If your background comes from C++ or Java you may understand more easily. Wha t tell you from your C++ knowledge o r from Java. Main concept is same here in C# with some better extensions and easy usability. For example since C++ Templates uses compile time, C# Generics also a feature of the runtime. They are basically the capacity to have type parameters lying on your type. Generics refer to classes and methods that work homogeneously on values of different types. They are a type of data structure that contains code that remains the same; though, the data type of the parameters can change with each use. We can also call them parameterized types or parametric polymorphism. Read more…
