C# Int32 and C# UInt32
In C#, Int32 known as a signed integer of 4 bytes which can store both types of values including negative and positive between the ranges of -2147483648 to +2147483647.
UInt32 known as an unsigned integer of 4 bytes which can store only positive values between the ranges of 0 to 4294967295.
Differences between 'Int32' and 'UInt32'
Int32 |
UInt32 |
Int32 stands for signed integer. |
UInt32 stands for unsigned integer. |
It's capacity to store the value is -2147483648 to +2147483647. |
It's capacity to store the value is 0 to 4294967295. |
It can store negative and positive integers. |
It can store only positive integers. |
It occupies 4-bytes space in the memory. |
It also occupies 4-bytes space in the memory. |

Declaration syntax: UInt32 variable; |
Example:
In this example, to explain the differences between Int32 and UInt32 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)
{
//Int32 value range
Console.WriteLine("Int32 value capacity...");
Console.WriteLine("Min: {0}, Max: {1}\n", Int32.MinValue, Int32.MaxValue);
//UInt32 value range
Console.WriteLine("UInt32 value capacity...");
Console.WriteLine("Min: {0}, Max: {1}\n", UInt32.MinValue, UInt32.MaxValue);
//Int32 array
Int32[] arr1 = { -2147483648, 0, 12320009, 2147480000, 2147483647 };
Console.WriteLine("UInt32 array elements...");
foreach (Int32 num in arr1)
{
Console.WriteLine(num);
}
Console.WriteLine();
//UInt32 array
UInt32[] arr2 = { 0, 100, 23000, 4294960000, 4294967295 };
Console.WriteLine("UInt32 array elements...");
foreach (UInt32 num in arr2)
{
Console.WriteLine(num);
}
//hit ENTER to exit
Console.ReadLine();
}
}
}
