C#中Int32和UInt32的区别

Int32： 此结构用于表示 32 位有符号整数。Int32 可以存储 -2147483648 到 +2147483647 范围内的负数和正数两种类型的值。

例子 ：

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

using System;
using System.Text;

public
class GeekDocsDemo {

// 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);
    }
}
}

运行结果：

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

-3

UInt32： UInt32结构用于表示 32 位无符号整数。UInt32 只能存储范围从 0 到 4294967295 的正值。

例子 ：

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

using System;
using System.Text;

public class GeekDocsDemo{

    // 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);
        }
    }
}

运行结果如下：

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

13
