Examples

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

' Visual Basic does not support explicit Decimal-to-Char
' conversion using either CType or CChar.
// 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);
   }
}
