What are advanced features of enumerations in C#?

In C#, advanced features of enumerations include the ability to define flags, use custom underlying types, and extend enums with methods.

Can you explain how to use flags with enumerations?

Certainly! You can use the [Flags] attribute to create bitwise enumerations, allowing you to combine multiple values.

Could you provide an example of using flags in an enum?

Sure! Here's an example:

[Flags]
enum Permissions
{
    None = 0,
    Read = 1,
    Write = 2,
    Execute = 4,
    All = Read | Write | Execute
}

This allows you to combine permissions like Permissions.Read | Permissions.Write.

What are the benefits of using custom underlying types for enums?

Using custom underlying types allows for better memory optimization and can enforce specific value ranges, enhancing type safety.
