long variable_name = value; C＃代码演示long关键字的示例 (C# code to demonstrate example of long keyword)

Here, we are declaring a long variable num, initializing it with the value 12345 and printing its value, type and size of a long type variable.

在这里，我们声明一个长变量num ，使用值12345对其进行初始化，并打印其值，类型和长型变量的大小。

using System;using System.Text;namespace Test{ class Program { static void Main(string[] args) { //variable declaration long num = 12345; //printing value Console.WriteLine("num: " + num); //printing type of variable Console.WriteLine("Type of num: " + num.GetType()); //printing size Console.WriteLine("Size of a long variable: " + sizeof(long)); //printing minimum & maximum value of long Console.WriteLine("Min value of long: " + long.MinValue); Console.WriteLine("Max value of long: " + long.MaxValue); //hit ENTER to exit Console.ReadLine(); } }}
