ToInt16 Method

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
)

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.


// Example of the decimal.ToInt16 and decimal.ToUInt16 methods.
using System;

class Example
{
   const string formatter = "{0,16}{1,19}{2,19}";

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

   // Convert the decimal argument; catch exceptions that are thrown.

      // Convert the argument to a ushort value.
      try

      catch (Exception ex)
      {
         UInt16Value = GetExceptionType(ex);

      outputBlock.Text += String.Format(formatter, argument,

      DecimalToU_Int16(outputBlock, new decimal(123000, 0, 0, false, 3));
