c# uint 和int

C＃Int64和C＃UInt64 (C# Int64 and C# UInt64)

In C#, Int64 known as a signed integer of 8 bytes which can store both types of values including negative and positive between the ranges of -9223372036854775808 to +9223372036854775807.

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 known as an unsigned integer of 8 bytes which can store only positive values between the ranges of 0 to 18446744073709551615.

UInt64，它是8个字节的无符号整数 ，只能存储0到18446744073709551615范围之间的正值 。

“ Int64”和“ UInt64”之间的区别 (Differences between 'Int64' and 'UInt64')

Example:

例：

In this example, to explain the differences between Int64 and UInt64 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 value range             Console.WriteLine("Int64 value capacity...");            Console.WriteLine("Min: {0}, Max: {1}\n", Int64.MinValue, Int64.MaxValue);            //UInt64 value range             Console.WriteLine("UInt64 value capacity...");            Console.WriteLine("Min: {0}, Max: {1}\n", UInt64.MinValue, UInt64.MaxValue);            //Int64 array            Int64[] arr1 = {
    					-9223372036854775808, 				0, 				1287822320009, 				9223372036854700000, 				9223372036854775807			};            Console.WriteLine("UInt64 array elements...");            foreach (Int64 num in arr1)            {
                   Console.WriteLine(num);            }            Console.WriteLine();            //UInt64 array            UInt64[] arr2 = {
    					0, 				1239289300, 				2399900900022, 				18446744073709000000, 				1844674407370955161 			};            Console.WriteLine("UInt64 array elements...");            foreach (UInt64 num in arr2)            {
                   Console.WriteLine(num);            }            //hit ENTER to exit            Console.ReadLine();        }    }}
