This documentation is archived and is not being maintained.

Decimal.ToInt16 Method

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
)
public static short ToInt16 (
	Decimal value
)
public static function ToInt16 (
	value : decimal
) : short

Parameters

value

A Decimal value.

Return Value

A 16-bit signed integer equivalent to value.

Exception typeCondition

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.

// Example of the Decimal::ToInt16 and Decimal::ToUInt16 methods.
using namespace System;
#define formatter "{0,16}{1,19}{2,19}"

// Get the exception type name; remove the namespace prefix.
String^ GetExceptionType( Exception^ ex )
{
   String^ exceptionType = ex->GetType()->ToString();
   return exceptionType->Substring( exceptionType->LastIndexOf( '.' ) + 1 );
}
