以下是 C# 中的一元运算符 -

+ - ! ~ ++ -- (type)* & sizeof

让我们了解一下 sizeof 运算符。 sizeof 返回数据类型的大小。

假设您需要查找 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来查找各种数据类型的大小 -

示例

实时演示

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
