BitConverter.GetBytes Method (Single)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Returns the specified single-precision floating point value as an array of bytes.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
<SecuritySafeCriticalAttribute> _
Public Shared Function GetBytes ( _
value As Single _
) As Byte()
[SecuritySafeCriticalAttribute]
public static byte[] GetBytes(
float value
)
Parameters
- value
Type: System.Single
The number to convert.
Return Value
Type: array<System.Byte[]
An array of bytes with length 4.
Examples
The following code example converts the bit patterns of Single values to Byte arrays with the GetBytes method.
' Example of the BitConverter.GetBytes( Single ) method.
Module Example
Const formatter As String = "{0,16:E7}{1,20}"
' Convert a Single argument to a Byte array and display it.
Sub GetBytesSingle(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal argument As Single)
Dim byteArray As Byte() = BitConverter.GetBytes(argument)
outputBlock.Text &= String.Format(formatter, argument, _
BitConverter.ToString(byteArray)) & vbCrLf
End Sub

outputBlock.Text &= String.Format(formatter, "Single", "Byte array") & vbCrLf
outputBlock.Text &= String.Format(formatter, "------", "----------") & vbCrLf
