class Program
{
static void Main()
{
ushort x = 536;
WriteLine($"The value of x is {x}");
//x = 100000; //1. This does not work because 100000 is too big to fit
}
}
- The ushort data type stores a maximum value of 65535
- Trying to force a number like 100000 into x in this example causes an error
- An error like this one would prevent the program from building successfully

Understanding Data Types in C# Using a Box Analogy:
Think of memory in a computer as a set of boxes, where each box can hold a certain amount of data. Some boxes are small (like byte
), some are medium-sized (like int
), and others are large (like long
). The type of a variable in C# determines the size of the 'box' we're going to use.
using static System.Console; class Program { static void Main() { byte smallBox = 200; // Small box can store values 0 to 255 WriteLine($"The small box contains: {smallBox}"); int mediumBox = 100000; // Medium box can store values from about -2 billion to 2 billion WriteLine($"The medium box contains: {mediumBox}"); long largeBox = 1000000000000; // Large box can store very large values WriteLine($"The large box contains: {largeBox}"); //byte overflowBox = 300; // This will cause a compile-time error because 300 can't fit in our small box (byte) } }
In this example, we create three boxes (byte
, int
, and long
) and try to put values in them. The byte
box, or smallBox
, can only hold values from 0
to 255
. The int
box, or mediumBox
, can hold much larger values, from about -2,147,483,648
to 2,147,483,647
. The long
box, or largeBox
, can hold very large values.
The commented line at the end of the program tries to put the value 300
into a byte
box, which can't fit. If you try to compile and run the code with this line uncommented, you would get a compile-time error, because 300
is too large for our byte
box.
In this way, memory in a computer is like a set of different-sized boxes. It's crucial to pick the right box (data type) for the data you're working with to prevent errors and optimize memory usage.
