What are some examples of generics in C#?

Can you explain what generics are in C#?

Generics in C# allow you to define classes, methods, and interfaces with a placeholder for the data type. This enables type safety and code reusability.

Can you give me some examples of how generics are used?

Sure! One common example is the List<T> class, which can store a list of any data type. For instance, List<int> for integers or List<string> for strings.

What about generic methods?

Generic methods allow you to define a method with a type parameter. For example, a method that swaps two items of any type can be defined as void Swap<T>(ref T x, ref T y).

Are there any limitations to using generics?

Yes, generics cannot be used with certain types like static members or non-parameterless constructors. Also, you can't use new() constraints with abstract classes.
