The following are the unary operators in C# −
+ - ! ~ ++ -- (type)* & sizeof
Let us learn about the sizeof operator. The sizeof returns the size of a data type.
Let’s say you need to find the size of int datatype −
sizeof(int)
For double datatype −
sizeof(double)
Let us see the complete example to find the size of various datatypes −
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(); } } }
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
