# Decimal.ToInt16 Method

.NET Framework 2.0

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

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

## Syntax

```'Declaration
Public Shared Function ToInt16 ( _
value As Decimal _
) As Short
'Usage
Dim value As Decimal
Dim returnValue As Short

returnValue = Decimal.ToInt16(value)
```
```public static short ToInt16 (
Decimal value
)
```
```public static function ToInt16 (
value : decimal
) : short
```

value

A Decimal value.

#### Return Value

A 16-bit signed integer equivalent to value.

## Exceptions

Exception typeCondition

OverflowException

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

## Example

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