C# Int16 and C# UInt16

In C#, Int16 known as a signed integer of 2 bytes which can store both types of values including negative and positive between the ranges of -32768 to +32767.

UInt16 known as an unsigned integer of 2 bytes which can store only positive values between the ranges of 0 to 65535.

Differences between 'Int16' and 'UInt16'

Int16 UInt16
Int16 stands for signed integer. UInt16 stands for unsigned integer.
It's capacity to store the value is -32768 to +32767. It's capacity to store the value is 0 to 65535.
It can store negative and positive integers. It can store only positive integers.
It occupies 2-bytes space in the memory. It also occupies 2-bytes space in the memory.
Declaration syntax:
Int16 variable;
Declaration syntax:
UInt16 variable;

Example:

In this example, to explain the differences between Int16 and UInt16 in C#, we are printing their minimum and maximum values, we are also declaring two arrays – arr1 is a signed integer type and arr2 is an unsigned integer type. Initializing the arrays with corresponding negative and positive values based on their capacity.

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            //Int16 value range 
            Console.WriteLine("Int16 value capacity...");
            Console.WriteLine("Min: {0}, Max: {1}\n", Int16.MinValue, Int16.MaxValue);

            //UInt16 value range 
            Console.WriteLine("UInt16 value capacity...");
            Console.WriteLine("Min: {0}, Max: {1}\n", UInt16.MinValue, UInt16.MaxValue);

            //Int16 array
            Int16[] arr1 = { -32768, 0, 1000, 32000, 32767};
            Console.WriteLine("UInt16 array elements...");
            foreach (Int16 num in arr1)
            {
                Console.WriteLine(num);
            }
            Console.WriteLine();

            //UInt16 array
            UInt16[] arr2 = { 0, 100, 23000, 65000, 65525};
            Console.WriteLine("UInt16 array elements...");
            foreach (UInt16 num in arr2)
            {
                Console.WriteLine(num);
            }

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

Int16 value capacity...
Min: -32768, Max: 32767

UInt16 value capacity...
Min: 0, Max: 65535

UInt16 array elements...
-32768
0
1000
32000
32767

UInt16 array elements...
0
100
23000
65000
