C# - Type Casting
Type casting is a way to convert a value from one data type to another in C#. There are two types of type casting in C#.
- Implicit Casting
- Explicit Casting
1. Implicit Casting
Implicit type casting is done automatically by the compiler when there is no possibility of losing data in the conversion. It works as converting a smaller type to a larger type size.
Example
int myInt = 12;
double myDouble = myInt; // Automatic casting: int to double
Console.WriteLine(myInt); // Outputs 12
Console.WriteLine(myDouble); // Outputs 122. Explicit Casting
Explicit type casting is done by the programmer when there is a possibility of losing data in the conversion. It works as converting a larger type to a smaller type size.
Example
double myDouble = 12.68;
int myInt = (int) myDouble; // Programmer casting: double to int
Console.WriteLine(myDouble); // Outputs 12.68
Console.WriteLine(myInt); // Outputs 12Explicit Type Casting with Lossing Data
when we explicitly cast a value to a smaller data type, there is a possibility of losing data or precision. In this case, the compiler truncates the value to fit into the smaller data type, which can result in a loss of information.
Example
float num1 = 10.5f;
int num2 = (int)num1; // num1 is explicitly cast to intOutput- 10Prev Next
