Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns the specified Unicode character value as an array of bytes.

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

Syntax

'Declaration
Public Shared Function GetBytes ( _
    value As Char _
) As Byte()
public static byte[] GetBytes(
    char value
)

Parameters

Return Value

Type: array<System.Byte[]
An array of bytes with length 2.

Examples

The following code example converts the bit patterns of Char values (Unicode characters) to Byte arrays with the GetBytes method.

' Example of the BitConverter.GetBytes( Char ) method.

Module Example

   Const formatter As String = "{0,10}{1,16}"

   ' Convert a Char argument to a Byte array and display it.
   Sub GetBytesChar(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal argument As Char)

      Dim byteArray As Byte() = BitConverter.GetBytes(argument)
      outputBlock.Text &= String.Format(formatter, argument, _
          BitConverter.ToString(byteArray)) & vbCrLf
   End Sub

   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      outputBlock.Text &= String.Format( _
          "This example of the BitConverter.GetBytes( Char ) " & _
          vbCrLf & "method generates the following " & _
          "output." & vbCrLf) & vbCrLf
      outputBlock.Text &= String.Format(formatter, "Char", "Byte array") & vbCrLf
      outputBlock.Text &= String.Format(formatter, "----", "----------") & vbCrLf

      ' Convert Char values and display the results.
      GetBytesChar(outputBlock, Chr(0))
      GetBytesChar(outputBlock, " "c)
      GetBytesChar(outputBlock, "*"c)
      GetBytesChar(outputBlock, "3"c)
      GetBytesChar(outputBlock, "A"c)
      GetBytesChar(outputBlock, "["c)
      GetBytesChar(outputBlock, "a"c)
      GetBytesChar(outputBlock, "{"c)
   End Sub
End Module
