How to use C # enumerated types

This article introduces the relevant knowledge of "how to use C# enumeration types". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

C # enumeration, an enumeration is a value type that consists of constants with many names (also known as enumeration tables). For example

Const int Monday=0; const int Tuesday=1;... Const Sunday=7

You can enumerate types with C #

Enum Week {Monday,Tuesday, Wednesday, Thursday,Friday,Saturday,Sunday}

Each constant in the C # enumeration corresponds to a numeric value, and if not specifically set, the enumeration starts at 0, and each subsequent value adds 1 to the previous value. If there are the following definitions

Enum Values {value1, value2, vlaue3=30, value4}

Among them, value1=0,value2=1,value3=30,value4=31

Int a = (int) Week.Friday

Public class food {public enum foodType {Pizza=1,Pasta,Spaghetti} public void GetFoodOrder (string Custname, foodType order) {Console.WriteLine ("the dinner of customer {0} is {1}", Custname,order);}} / / C# enumeration type class Program {static void Main (string args) {food myfood = new food (); myfood.GetFoodOrder ("Scoopy", (food.foodType.Pizza)) Console.WriteLine ("you are enjoying our" + (int) food.foodType.Pizza+ "staple food"); Console.ReadLine ();}}
