How to print the size of various data types in C#
Theodore Kelechukwu OnyejiakuOverview
The size of a data type is the size it takes in memory. Their sizes vary. This size is represented in bytes. We can use the sizeof() method to get their sizes.
Syntax
sizeof(datatype)
syntax for sizeof() method in C#
Parameters
datatype: This is the datatype whose size we want to get in memory.
Return value
The value returned is the size of a data type in memory.
Example
using System;
class DatatypeSize
{
static void Main()
{
// print sizes of some datatypes
Console.WriteLine("sizeof(int): {0}", sizeof(int)); // 4
Console.WriteLine("sizeof(float): {0}", sizeof(float)); // 4
Console.WriteLine("sizeof(char): {0}", sizeof(char)); // 2
Console.WriteLine("sizeof(double): {0}", sizeof(double)); // 8
Console.WriteLine("sizeof(bool): {0}", sizeof(bool)); // 1
}
}Printing the size of some datatypes in C#
Explanation
- Lines 7–11: We get the sizes of some data types in memory using the
sizeof()method. Then we print the results to the console.
