What are the different forms of type conversion in C#?
In C#, the forms of type conversion include the following:
- Implicit Conversion: Conversion that happens automatically when the target type has a larger range than the source type, without the need to explicitly specify a conversion operator. For example, assigning an integer to a long integer variable.
- Explicit Conversion: When the range of the target type is smaller than that of the source type, it is necessary to use explicit conversion operators for the conversion. For example, converting a long integer to an integer type.
- There are several methods available in C# for type conversion, such as the Convert class, Parse method, and TryParse method.
- Type casting: Use the type casting operator to convert one type to another. For example, use (int) to convert a floating point number to an integer type.
- The “as” operator is used to convert an object to another type, returning null if the conversion fails.
- is operator: used to determine if an object is an instance of a certain type, and returns a boolean value.
- Custom type conversion: Custom type conversion can be defined by overloading conversion operators. For example, overloading implicit or explicit conversion operators can be used to achieve custom type conversion.
