Last Updated :

Given the normal Console in C#, the task is to check if the NUM LOCK is on or off through Console.
Approach: This can be done using the NumberLock property in the Console class of the System package in C#. This property gets a value indicating whether the NUM LOCK keyboard toggle is turned on or turned off.
Program 1: When the NUM LOCK is on
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace GFG {
class Program {
static void Main( string [] args)
{
Console.WriteLine( "Is NUM LOCK on: {0}" ,
Console.NumberLock);
}
}
}

Output:
Program 2: When the NUM LOCK is off
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace GFG {
class Program {
static void Main( string [] args)
{
Console.WriteLine( "Is NUM LOCK on: {0}" ,
Console.NumberLock);
}
}
}
