C# 中的一元运算符是什么?
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 返回数据类型的尺寸。
假设您需要查找 int 数据类型的尺寸 −
sizeof(int)
对于 double 数据类型 −
sizeof(double)
让我们看一个完整的示例来查找各种数据类型的尺寸 −
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
