C# program to demonstrate the use of ToObject() method of Enum class

Here, we are going to demonstrate the use of ToObject() method of Enum class in C#.Net.
Submitted by Nidhi, on April 17, 2021

Here, we will learn about the ToObject() method of the Enum class. This method is used to convert the value to an object that can be typecast to an enum object. This is nine times overloaded method.

Syntax:

object Enum.ToObject(Type enumType, Byte	value);
object Enum.ToObject(Type enumType, Int16	value);
object Enum.ToObject(Type enumType, Int32	value);
object Enum.ToObject(Type enumType, Int64	value);
object Enum.ToObject(Type enumType, Object	value);
object Enum.ToObject(Type enumType, SByte	value);
object Enum.ToObject(Type enumType, UInt16	value);
object Enum.ToObject(Type enumType, UInt32	value);
object Enum.ToObject(Type enumType, UInt64	value);

Parameter:

• enumType : Type of enum object.
• value : Value to be converted to object.

Return value:

This method returns the object on the basis of the passed value.

Exception:

• System.ArgumentException
• System.ArgumentNullException

Program:

The source code to demonstrate the use of ToObject() method of Enum class is given below. The given program is compiled and executed successfully.

using System;

class Sample
{
    enum Directions { EAST=0,WEST=1,NORTH=2,SOUTH=3};
   
    //Entry point of Program
    static public void Main()
    {
        Directions dir;
        Byte  value1 = 1;
        Int16 value2 = 2;
        Int32 value3 = 3;

        //ToObject with Byte value
        dir = (Directions)Enum.ToObject(typeof(Directions), value1);
        Console.WriteLine(Enum.GetName(typeof(Directions),dir));

        //ToObject with Int16 value
        dir = (Directions)Enum.ToObject(typeof(Directions), value2);
        Console.WriteLine(Enum.GetName(typeof(Directions), dir));
        
        //ToObject with Int32 value
        dir = (Directions)Enum.ToObject(typeof(Directions), value3);
        Console.WriteLine(Enum.GetName(typeof(Directions), dir));
    }
}

Output:

WEST
NORTH
SOUTH
