What is Type casting in C#?

Csharp Programming Server Side Programming

Type casting is converting one type of data to another type. The two forms are −

Implicit type conversion − These conversions are performed by C# in a type-safe manner. For example, are conversions from smaller to larger integral types and conversions from derived classes to base classes.

Explicit type conversion− These conversions are done explicitly by users using the pre-defined functions. Explicit conversions require a cast operator.

The following are the built-in type conversion methods −

Sr.No	Method & Description
1	ToBoolean Converts a type to a Boolean value, where possible.
2	ToByte Converts a type to a byte.
3	ToChar Converts a type to a single Unicode character, where possible.
4	ToDateTime Converts a type (integer or string type) to date-time structures.
5	ToDecimal Converts a floating point or integer type to a decimal type.
6	ToDouble Converts a type to a double type.

The following example convert integer to string type −

         int i = 20;

         Console.WriteLine(i.ToString());
