Cast int to enum in C#

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
}

public enum EmloyeeRole

{

None = 0,

Manager = 1,

Admin = 2,

Operator = 3

}

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


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

EmloyeeRole role = EmloyeeRole.Manager;

int roleInterger = (int)role;

Same like above, simply type cast the integer to enum


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

int roleInterger = 2;

EmloyeeRole role = (EmloyeeRole)roleInterger;

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);

string roleString = "Operator";

EmloyeeRole role =

(EmloyeeRole)Enum.Parse(typeof(EmloyeeRole), roleString);

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


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

EmloyeeRole role = EmloyeeRole.Manager;

string roleString = role.ToString();
