C#中Int64和UInt64的区别

Int64 ：此Struct 用于表示 64 位有符号整数。所述的Int64可以两种类型的值，包括-9,223,372,036,854,775,808范围之间负的和正的存储9，223,372,036,854,775,807

例子 ：

C#

// C# program to show the
// difference between Int64
// and UInt64
  
using System;
using System.Text;
  
public
class GFG {
  
  // Main Method
  static void Main(string[] args) {
  
    // printing minimum & maximum values
    Console.WriteLine("Minimum value of Int64: " 
                      + Int64.MinValue);
    Console.WriteLine("Maximum value of Int64: " 
                      + Int64.MaxValue);
    Console.WriteLine();
  
    // Int64 array
    Int64[] arr1 = {-3, 0, 1, 3, 7};
  
    foreach (Int64 i in arr1)
    { 
      Console.WriteLine(i);
    }
  }
}

输出：

Minimum value of Int64: -9223372036854775808
Maximum value of Int64: 9223372036854775807

UInt64 ：此结构用于表示 64 位无符号整数。所述UINT64只能存储唯一积极的值，其范围为0〜18,446,744,073,709,551,615。

例子 ：

C＃

// C# program to show the 
// difference between Int64 
// and UInt64
  
using System;
using System.Text;
  
public class GFG{
      
    // Main Method
    static void Main(string[] args)
    {
  
        //printing minimum & maximum values
        Console.WriteLine("Minimum value of UInt64: "
                          + UInt64.MinValue);
        Console.WriteLine("Maximum value of UInt64: "
                          + UInt64.MaxValue);
        Console.WriteLine();
          
        //Int64 array
        UInt64[] arr1 = { 13, 0, 1, 3, 7};
          
        foreach (UInt64 i in arr1)
        {
            Console.WriteLine(i);
        }
    }
}

输出：

Minimum value of UInt64: 0
Maximum value of UInt64: 18446744073709551615
