#367 – Iterating through All Possible Values of an Enumeration Type
There are occasions when it’s desirable to iterate through all possible values of an enumeration type. You can do this using the static Enum.GetValues method. Suppose that we have an enumeration type...

#457 – Converting Between enums and their Underlying Type
When you declare an enum, by default each enumerated value is represented internally with an int. (System.Int32 – 4 bytes). You can convert between values of the underlying type and enum values using...

#458 – Errors While Converting Between enum and Underlying Type
You can convert to an enum value from its underlying type by casting the underlying type (e.g. int) to the enum type. However, when you cast a value that doesn’t have a corresponding enumerator in the...

#459 – Assigning a Value of a Different Type to an enum
You can convert to an enum value from its underlying type by casting the underlying type (e.g. int) to the enum type. You can also assign a value of a different type, one that does not match the...

#460 – Converting from a String to an Enum Type
You can convert a string to the corresponding enumerator in an enum type by using the Enum.Parse method. This is a static method that takes the specific enumerated type and a string value and returns...

#461 – Enumeration Elements Don’t Need to Be Sequential
Enumeration elements are implicitly set to consecutive integers, starting at 0, as indicated in the comments below. // Default type is int public enum Mood { Crabby, // 0 Happy, // 1 Petulant, // 2...

#462 – Duplicate Enumerators in an Enumerated Type
When defining a new enumerated type, you can define multiple enumerators that have the same underlying value. You might do this when you have a finite set of enumerated values and you want to map them...

#463 – Enumerated Values Can Be Any Constant Expression
When you define an enum, the individual values can be implicitly defined (one greater than the previous value), assigned to a constant, or assigned to any constant expression. In the definition of the...

#464 – Getting an Enumeration’s Underlying Type at Runtime
You can use the Enum.GetUnderlyingType static method to find out what the underlying type is that is being used to store an enumerated type’s enumerated values. public enum Moods : byte { NOMOOD = 0,...

#626 – Nested Type Options
When you declare one type inside of another, the outer type must be either a class or a struct. The inner (nested) type can be one of the following: class, struct, interface, delegate or enum. Here...

#982 – An Enum Type Can Store a Maximum of 32 Flags
When you store a boolean value in a bool type, each boolean value uses 1 byte, or 8 bits–the size of a bool instance. You can be more efficient in storing boolean values by using each bit within a...

#1,025 – Converting between enum Types
You can convert between two different enum types as long as they both use the same underlying type (e.g. int). You use an explicit cast to do the conversion. Assuming two enum types that by default...

#1,026 – Checking a Flagged enum Type for Validity
You normally use the Enum.IsDefined method to check whether a particular enum value is a valid value. This method does not work on flagged enums. Assuming the following enum type: [Flags] public enum...
