Before discussing C# Data Types, you should know the word datatype. So what is a data type? It is the type of data that a variable can store in the form of value. It can be of any kind, i.e., numerical data, textual data, character data, etc. I hope you got it. If you still have any queries related to C# Data Types, comment below. Now let’s discuss datatypes in C#.
C# Data Types Description
There are several C# Data Types look below:
| Data type | Size of Datatype | Description of data type |
|---|---|---|
| int | 4 bytes | Stores whole numbers, without decimals / positive or negative |
| float | 4 bytes | Stores fractional numbers, containing one or more decimals. Sufficient for storing 6-7 decimal digits |
| double | 8 bytes | Stores fractional numbers, containing one or more decimals. Sufficient for storing 15 decimal digits |
| char | 2 bytes | Stores a single character/letter/number, or ASCII values and it is surrounded by single comma like ‘a’ |
| bool | 1 bit | Stores true or false values or on or off like |
| string | 2 bytes per character | Stores a sequence of characters(i.e text), surrounded by double quotes(“”) |
| long | 8 bytes | Stores whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |
Declaring Variable with C# Data Types with output
using System;
namespace Codelikechamp
{
class Program
{
static void Main(string[] args)
{
int Num = 5; // integer (whole number)
double DoubleNum = 5.99D; // floating point number
char Letter = 'D'; // character
bool Bool = true; // boolean
string Text = "Hello"; // string
Console.WriteLine(Num);
Console.WriteLine(DoubleNum);
Console.WriteLine(Letter);
Console.WriteLine(Bool);
Console.WriteLine(Text);
}
}
}
Output of C# Data Types
5 5.99 D true Hello
