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

public static explicit operator char (
	decimal value
)

Parameters

value
Type: System.Decimal
A Decimal to convert.

Return Value

Type: System.Char
A Unicode character that represents the converted Decimal.

ExceptionCondition
OverflowException

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

The following code example converts Decimal numbers to Char values (Unicode characters) using the explicit Decimal to Char conversion.


// Example of the explicit conversion from decimal to char.
using System;

class Example
{
   const string formatter = "{0,17}{1,19}{2,12}";

   // 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.
   public static void DecimalToChar(System.Windows.Controls.TextBlock outputBlock, decimal argument)
   {
      object CharValue;

      // Convert the argument to a char value.
      try
      {
         CharValue = (char)argument;
         outputBlock.Text += String.Format(formatter, argument, CharValue,
             ((ushort)(char)CharValue).ToString("X4")) + "\n";
      }
      catch (Exception ex)
      {
         CharValue = GetExceptionType(ex);
         outputBlock.Text += String.Format(formatter, argument, CharValue, null) + "\n";
      }
   }

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      outputBlock.Text += 
          "This example of the explicit conversion from decimal " +
          "\nto char generates the following output. It " +
          "displays \nseveral converted decimal values.\n" + "\n";
      outputBlock.Text += String.Format(formatter, "decimal argument",
          "char/exception", "hex code") + "\n";
      outputBlock.Text += String.Format(formatter, "----------------",
          "--------------", "--------") + "\n";

      // Convert decimal values and display the results.
      DecimalToChar(outputBlock, 33.33M);
      DecimalToChar(outputBlock, 55.5M);
      DecimalToChar(outputBlock, 77.7M);
      DecimalToChar(outputBlock, 123M);
      DecimalToChar(outputBlock, 123.999M);
      DecimalToChar(outputBlock, 143.43M);
      DecimalToChar(outputBlock, 170M);
      DecimalToChar(outputBlock, 188.88M);
      DecimalToChar(outputBlock, 222M);
      DecimalToChar(outputBlock, 244M);
      DecimalToChar(outputBlock, 488M);
      DecimalToChar(outputBlock, 8217M);
      DecimalToChar(outputBlock, 8250M);
      DecimalToChar(outputBlock, 16383M);
      DecimalToChar(outputBlock, 32768M);
      DecimalToChar(outputBlock, 65535.999M);
      DecimalToChar(outputBlock, 65536M);
      DecimalToChar(outputBlock, -0.999M);
      DecimalToChar(outputBlock, -1M);
   }
