Difference between Int32 and UInt32 in C#

Int32: This Struct is used to represents 32-bit signed integer. The Int32 can store both types of values including negative and positive between the ranges of -2147483648 to +2147483647.

Example :

C#

// C# program to show the
// difference between Int32
// and UInt32

using System;
using System.Text;

public
class GFG {

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

    // printing minimum & maximum values
    Console.WriteLine("Minimum value of Int32: "
                      + Int32.MinValue);
    Console.WriteLine("Maximum value of Int32: "
                      + Int32.MaxValue);
    Console.WriteLine();

    // Int32 array
    Int32[] arr1 = {-3, 0, 1, 3, 7};

    foreach (Int32 i in arr1)
    {
      Console.WriteLine(i);
    }
  }
}

Output:

Minimum value of Int32: -2147483648
Maximum value of Int32: 2147483647

UInt32: This Struct is used to represents 32-bit unsigned integer. The UInt32 can store only positive value only which ranges from 0 to 4294967295.

Example :

C#

// C# program to show the
// difference between Int32
// and UInt32

using System;
using System.Text;

public class GFG{

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

        // printing minimum & maximum values
        Console.WriteLine("Minimum value of UInt32: "
                          + UInt32.MinValue);
        Console.WriteLine("Maximum value of UInt32: "
                          + UInt32.MaxValue);
        Console.WriteLine();

        // Int32 array
        UInt32[] arr1 = { 13, 0, 1, 3, 7};

        foreach (UInt32 i in arr1)
        {
            Console.WriteLine(i);
        }
    }
}

Output:

Minimum value of UInt32: 0
Maximum value of UInt32: 4294967295
