Create Non-Nullable Types in C#

Question

How to create non-nullable value types like int, bool, etc. in C#?

Answer 1

You can define a struct:

A struct type is a value type that is typically used to encapsulate small groups of related variables, such as the coordinates of a rectangle or the characteristics of an item in an inventory. The following example shows a simple struct declaration:

public struct Book
{
    public decimal price;
    public string title;
    public string author;
}

However, you can't define aliases like int for System.Int32 and need to refer with the full name MyNamespace.Book (or Book with using MyNamespace;) to your struct.
