Difference between Int16 and UInt16 in C#

Last Updated : 15 Jul, 2025

Int16: This Struct is used to represents 16-bit signed integer. The Int16 can store both types of values including negative and positive between the ranges of -32768 to +32767.

Example :

C# 
// C# program to show the
// difference between Int16
// and UInt16

using System;
using System.Text;

public
class GFG {

  // Main Method
  static void Main(string[] args) {

    // printing minimum & maximum values
    Console.WriteLine("Minimum value of Int16: " 
                      + Int16.MinValue);
    Console.WriteLine("Maximum value of Int16: " 
                      + Int16.MaxValue);
    Console.WriteLine();

    // Int16 array
    Int16[] arr1 = {-3, 0, 1, 3, 7};

    foreach (Int16 i in arr1)
    { 
      Console.WriteLine(i);
    }
  }
}

Output:

Minimum value of Int16: -32768
Maximum value of Int16: 32767

UInt16: This Struct is used to represents 16-bit unsigned integer. The UInt16 can store only positive value only which ranges from 0 to 65535.

Example :

C# 
// C# program to show the 
// difference between Int16 
// and UInt16

using System;
using System.Text;

public class GFG{
    
    // Main Method
    static void Main(string[] args)
    {

        // printing minimum & maximum values
        Console.WriteLine("Minimum value of UInt16: "
                          + UInt16.MinValue);
        Console.WriteLine("Maximum value of UInt16: "
                          + UInt16.MaxValue);
        Console.WriteLine();
        
        // Int16 array
        UInt16[] arr1 = { 13, 0, 1, 3, 7};
        
        foreach (UInt16 i in arr1)
        {
            Console.WriteLine(i);
        }
    }
}

Output:

Minimum value of UInt16: 0
Maximum value of UInt16: 65535
