- Operator (C# Reference)

The - operator can function as either a unary or a binary operator.

Unary - operators are predefined for all numeric types. The result of a unary - operation on a numeric type is the numeric negation of the operand.

Binary - operators are predefined for all numeric and enumeration types to subtract the second operand from the first.

Delegate types also provide a binary - operator, which performs delegate removal.

User-defined types can overload the unary - and binary - operators. For more information, see operator (C# Reference).
