Decimal Narrowing Conversion (Decimal to Int16)

 
equivalentCodeEntityM:System.Decimal.ToInt16(System.Decimal)

Defines an explicit conversion of a Decimal to a 16-bit signed integer.

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

Public Shared Narrowing Operator CType (
	value As Decimal
) As Short

Parameters

value
Type: System.Decimal

The value to convert.

Return Value

Type: System.Int16

A 16-bit signed integer that represents the converted Decimal.

Exception Condition
OverflowException

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

This operator supports the explicit conversion of a Decimal to a Int16. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to an Int16 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToInt16 or the Convert.ToInt16(Decimal) method.

The following example converts Decimal numbers to Int16 values by using the explicit Decimal to Int16 conversion.

' Decimal to UShort.

    Const formatter As String = "{0,16}{1,19}{2,19}"

        Dim UInt16Value As Object

        ' Convert the argument to a Short value.
