如何使用 sizeof() 运算符查找 C# 中的数据类型或变量的大小
sizeof() 数据类型返回数据类型的大小。假设你需要查找 int 数据类型的大小 −
sizeof(int);
对于双精度数据类型
sizeof(double);
我们来看一个完整的示例来查找各种数据类型的大小 −
示例
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
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
