Some operators of C #

1. typeof OPERATOR:

Obtain the type of the system prototype object.

For example, type (INT)

2. As Operator

It is used to explicitly convert a value to a specified reference type through reference conversion or packing conversion. Unlike the display type conversion, as will not produce any exceptions. If the conversion fails, the result value is null.

For example, string S = 'A' as string;

3. Is Operator

It is used to dynamically check whether the object type is compatible with the given type during runtime.

For example, 1 is int

4. Checked and unchecked Operators

Used to control overflow checks in the current environment during integer arithmetic operations.
