How to use C# sizeof operator to find out the size of a type
Using sizeof operator
To obtain this information, use the sizeof operator.
Syntax
It has this general form:
sizeof(type)Example
Example for sizeof operator
using System;// w w w.jav a 2s . c o m
using System.Globalization;
struct MyValueType
{
public short s;
public int i;
public long l;
}
public class MainClass{
static void Main(string[] args)
{
Console.WriteLine("sizeof operations");
unsafe
{
Console.WriteLine("The size of short is {0}", sizeof(short));
Console.WriteLine("The size of int is {0}", sizeof(int));
Console.WriteLine("The size of long is {0}", sizeof(long));
Console.WriteLine("The size of MyValueType is {0}\n", sizeof(MyValueType));
}
}
}
The code above generates the following result.
