C# - Type Conversion

The type conversion allows you to convert one datatype value to another data type. It is also known as type casting in C#.

There are two type of conversions: Implicit and explicit

Implicit Conversion

Implicit conversions are performed by the compiler automatically when there is no risk of data loss. For example, converting from smaller data types to larger ones.

int numInt = 10; 
double numDouble = numInt; // Implicit conversion from int to double

In above example, an int is implicitly converted to a double without any explicit casting required.

Explicit Conversion (Casting)

Explicit conversions require casting and used when there is a potential loss of data. You can explicitly cast by placing the desired type in parentheses before the variable you want to convert.

double numDouble = 10.5; 
int numInt = (int)numDouble; // Explicit conversion from double to int

Here, the double value is explicitly cast to an int, and any decimal information is truncated.
