ToByte Method (Single)

Convert.ToByte Method (Single)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Converts the value of the specified single-precision floating point number to an equivalent 8-bit unsigned integer.

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

public static byte ToByte(
	float value
)

Parameters

value
Type: System.Single
A single-precision floating point number.

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.

ExceptionCondition
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);
   outputBlock.Text += String.Format("The byte as a float is {0}.",
      floatVal) + "\n";

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