c# int uint32_C＃中Int32和UInt32之间的区别

c# int uint32

C＃Int32和C＃UInt32 (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.

在C＃中， Int32被称为4字节的有符号整数，它可以存储-2147483648至+2147483647范围之间的两种类型的值，包括负数和正数。

UInt32 known as an unsigned integer of 4 bytes which can store only positive values between the ranges of 0 to 4294967295.

UInt32，它是4个字节的无符号整数 ，只能存储0到4294967295范围之间的正值。

‘Int32’和’UInt32’之间的区别 (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: Int32 variable;	Declaration syntax: UInt32 variable;

32位	UInt32
Int32代表有符号整数。	UInt32代表无符号整数。

Example:

例：

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.

在此示例中，为了解释C＃中Int32和UInt32之间的区别，我们将打印它们的最小值和最大值，同时还声明了两个数组– arr1是有符号整数类型，而arr2是无符号整数类型。根据其容量用相应的负值和正值初始化数组。

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();
        }
    }
}
