Decimal.ToInt16 Method

July 28, 2014

Converts the value of the specified Decimal to the equivalent 16-bit signed integer.

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

public static short ToInt16(
	decimal value
)

Parameters

value
Type: System.Decimal
A Decimal value.

Return Value

Type: System.Int16
A 16-bit signed integer equivalent to value.

ExceptionCondition
OverflowException

value is less than Int16.MinValue or greater than Int16.MaxValue.

The following code example converts Decimal numbers to Int16 values using the ToInt16 method.
