Convert.ToByte Method (Decimal)

Converts the value of the specified Decimal number to an equivalent 8-bit unsigned integer.

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

public static byte ToByte (
	decimal value
)
public static byte ToByte (
	Decimal value
)
public static function ToByte (
	value : decimal
) : byte
Not applicable.

Parameters

value

A Decimal number.

Return Value

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.
Exception typeCondition

OverflowException

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);
    System.Console.WriteLine("The byte as a decimal is {0}.",
        decimalVal);

    // Decimal to byte conversion can overflow.
    try {
        byteVal = System.Convert.ToByte(decimalVal);
        System.Console.WriteLine("The Decimal as a byte is {0}.",
            byteVal);
    }
    catch (System.OverflowException) {
        System.Console.WriteLine(
            "The decimal value is too large for a byte.");
    }
}

public void ConvertByteDecimal(ubyte byteVal)
{
    System.Decimal decimalVal;

    // Byte to decimal conversion will not overflow.
    decimalVal = System.Convert.ToDecimal(byteVal);
    System.Console.WriteLine("The byte as a decimal is {0}.", decimalVal);

    // Decimal to byte conversion can overflow.
    try {        
        byteVal = System.Convert.ToByte(decimalVal);
        System.Console.WriteLine("The Decimal as a byte is {0}.", 
            System.Convert.ToString(byteVal));
    }
    catch (System.OverflowException exp) {        
        System.Console.WriteLine(
            "The decimal value is too large for a byte.");
    }
} //ConvertByteDecimal
