BitConverter.GetBytes Method (Int16)

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

Returns the specified 16-bit signed integer value as an array of bytes.

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

Syntax

'Declaration
<SecuritySafeCriticalAttribute> _
Public Shared Function GetBytes ( _
    value As Short _
) As Byte()

[SecuritySafeCriticalAttribute]
public static byte[] GetBytes(
    short 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 Int16 values to Byte arrays with the GetBytes method.

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

Module Example

   Const formatter As String = "{0,10}{1,13}"

   ' Convert a Short argument to a Byte array and display it.
   Sub GetBytesInt16(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal argument As Short)

      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( Short ) " & _
          vbCrLf & "method generates the following " & _
          "output." & vbCrLf) & vbCrLf
      outputBlock.Text &= String.Format(formatter, "Short", "Byte array") & vbCrLf
      outputBlock.Text &= String.Format(formatter, "-----", "----------") & vbCrLf

      ' Convert Short values and display the results.
      GetBytesInt16(outputBlock, 0)
      GetBytesInt16(outputBlock, 15)
      GetBytesInt16(outputBlock, -15)
      GetBytesInt16(outputBlock, 10000)
      GetBytesInt16(outputBlock, -10000)
      GetBytesInt16(outputBlock, Short.MinValue)
      GetBytesInt16(outputBlock, Short.MaxValue)
   End Sub
End Module
