C#中的Int64和UInt64之间的区别
C＃Int64和C＃UInt64
在C＃中，Int64被称为8字节的有符号整数，它可以存储-9223372036854775808到+9223372036854775807范围之间的两种类型的值，包括负数和正数。
UInt64，它是8个字节的无符号整数，只能存储0到18446744073709551615615范围之间的正值。

示例
在此示例中，为了解释C＃中Int64和UInt64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)
{
//Int64值范围
Console.WriteLine("Int64 value capacity...");
Console.WriteLine("Min: {0}, Max: {1}\n", Int64.MinValue, Int64.MaxValue);
//UInt64值范围
Console.WriteLine("UInt64 value capacity...");
Console.WriteLine("Min: {0}, Max: {1}\n", UInt64.MinValue, UInt64.MaxValue);
//Int64数组
Int64[] arr1 = {
-9223372036854775808,
0,
1287822320009,
9223372036854700000,
9223372036854775807
};
Console.WriteLine("UInt64 array elements...");
foreach (Int64 num in arr1)
{
Console.WriteLine(num);
}
Console.WriteLine();
//UInt64数组
UInt64[] arr2 = {
0,
1239289300,
2399900900022,
18446744073709000000,
1844674407370955161
};
Console.WriteLine("UInt64 array elements...");
foreach (UInt64 num in arr2)
{
Console.WriteLine(num);
}
//按ENTER退出
Console.ReadLine();
}
}
}输出结果
