Decimal.Increment Operator

Increments the Decimal operand by 1.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Shared Operator ++ ( _
	d As Decimal _
) As Decimal

Parameters

d
Type: System.Decimal
The value to increment.

Return Value

Type: System.Decimal
The value of d incremented by 1.

ExceptionCondition
OverflowException

The return value is less than MinValue or greater than MaxValue.

The following code example applies the Increment operator to several Decimal values.
