Enum coversion operations (int to enum, enum to int, string to enum, enum to string)

This post describes how can we convert enum into different data types. These are very often used operation. This is very simple to achieve thing. Let take an exmaple

public enum EmloyeeRole
{
  None = 0,
  Manager = 1,
  Admin = 2,
  Operator = 3
}

enum to int

To convert a enum to interger simply type cast the enum into integer

EmloyeeRole role = EmloyeeRole.Manager;
int roleInterger = (int)role;

int to enum

Same like above, simply type cast the integer to enum

int roleInterger = 2;
EmloyeeRole role = (EmloyeeRole)roleInterger;

string to enum

If you have string value and you want to type cast that into enum, then you can use Enum.Parse

string roleString = "Operator";
EmloyeeRole role = 
  (EmloyeeRole)Enum.Parse(typeof(EmloyeeRole), roleString);

enum to string

This is the simplest one, just use the ToString method of the enum

EmloyeeRole role = EmloyeeRole.Manager;
string roleString = role.ToString();
