	decimal value

Return Value

Type: System.Byte
value rounded to the nearest 8-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.


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

The following code sample illustrates the use of ToByte, converting a Decimal value to a Byte :

public void ConvertByteDecimal(byte byteVal)
   decimal decimalVal;

   // Byte to decimal conversion will not overflow.
   decimalVal = System.Convert.ToDecimal(byteVal);
   outputBlock.Text += String.Format("The byte as a decimal is {0}.",
      decimalVal) + "\n";

   // Decimal to byte conversion can overflow.
      byteVal = System.Convert.ToByte(decimalVal);
      outputBlock.Text += String.Format("The Decimal as a byte is {0}.",
         byteVal) + "\n";
   catch (System.OverflowException)
      outputBlock.Text += String.Format(
         "The decimal value is too large for a byte.") + "\n";
