Convert.ToByte Método (Single)

The valor of the specified Single-converts Precisão número de ponto flutuante to an equivalente 8-bit unsigned integer.

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

public static byte ToByte(
	float value
)

Parâmetros

value
Tipo: System.Single
A single-Precisão número de ponto flutuante.

Valor de retorno

Tipo: 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.

ExceçãoCondição
OverflowException

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

The following code sample illustrates the use of ToByte, converting a Single (float) value to a Byte :

		public void ConvertByteSingle(byte byteVal) {
			float floatVal;

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

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


public void ConvertByteSingle(ubyte byteVal)
{
    float floatVal;

    // Byte to float conversion will not overflow.
    floatVal = System.Convert.ToSingle(byteVal);
    System.Console.WriteLine("The byte as a float is {0}.", 
        System.Convert.ToString(floatVal));

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