的sizeof()
数据类型返回一个数据类型的大小。假设您需要找到int数据类型的大小-
sizeof(int);
对于双数据类型
sizeof(double);
让我们看看完整的示例以查找各种数据类型的大小-
using System; namespace Demo { class Program { static void Main(string[] args) { Console.WriteLine("The size of int is {0}", sizeof(int)); Console.WriteLine("The size of int is {0}", sizeof(char)); Console.WriteLine("The size of short is {0}", sizeof(short)); Console.WriteLine("The size of long is {0}", sizeof(long)); Console.WriteLine("The size of double is {0}", sizeof(double)); Console.ReadLine(); } } }
输出结果
The size of int is 4 The size of int is 2 The size of short is 2 The size of long is 8 The size of double is 8
