C # mutual conversion of Enum, Int, and string

【C # mutual conversion of Enum, Int, and string]

1. Enum --> string

(1) Use the object. tostring () method: for example:Colors. Green. tostring() The value is a "green" string; (2) use the static methods of Enum to getname and getnames: public static string getname (type enumtype, object value) public static string [] getnames (type enumtype) Example: enum. getname (typeof (colors), 3) andEnum. getname (typeof (colors), colors. Blue ))All values are "blue"Enum. getnames (typeof (colors ))Returns an enumerated string array.

2. String --> Enum

(1) Use the static method parse of Enum: public static object parse (type enumtype, string value) for example:(Colors) enum. parse (typeof (colors), "Red ")

3. Enum --> int

(1) because the enumeration base type is an integer other than char, it can be forcibly converted. For example:(INT) colors. Red, (Byte) colors. Green

4. int --> Enum

(1) An integer can be forcibly converted to an enumeration type. For example: colors color = (colors) 2, then color is colors. Blue (2) using the static method toobject of enum. Public static object toobject (type enumtype, int value) Example: colors color =(Colors) enum. toobject (typeof (colors), 2)The color is colors. Blue.

5. determine whether an integer is defined in the enumeration method: enum. isdefined

Public static bool isdefined (type enumtype, object Value) Example:Enum. isdefined (typeof (colors), n ))
