Encoding.GetEncoding Method

Returns the encoding associated with the specified name.

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

Public Shared Function GetEncoding ( _
	name As String _
) As Encoding


Type: System.String
The name of the preferred encoding.

Return Value

Type: System.Text.Encoding
The object associated with the specified name.


name is not the name of a valid encoding.

The following table lists valid values for the name parameter. Except for "utf-16LE", they correspond to the strings returned by each encoding's WebName property.






UnicodeEncoding (little-endian)


UnicodeEncoding (big-endian)


UnicodeEncoding (little-endian)

The name parameter is not case-sensitive. For example, the method returns a UnicodeEncoding object if name is either "utf-16" or 'UTF-16".

GetEncoding returns a cached instance with default settings. To get an instance with different settings, call the appropriate constructors of derived classes. For example, the UnicodeEncoding class provides a constructor that allows enabling of error detection.

Platform Notes

Silverlight for Windows Phone Silverlight for Windows Phone

 If you pass an invalid code page name to GetEncoding, the method throws PlatformNotSupportedException instead of ArgumentException.

The following example instantiates several encoding objects, including two that are returned by the GetEncoding method. It then checks them for equality.

Imports System.Text

Public Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Get a UTF-16 encoding.
      Dim e16_1 As Encoding = Encoding.GetEncoding("utf-16")

      ' Instantiate a second UTF-16 encoding.
      Dim e16_2 As Encoding = New UnicodeEncoding()

      ' Instantiate a Unicode little endian encoding.
      Dim le As Encoding = New UnicodeEncoding(False, True)

      ' Instantiate a Unicode big endian encoding.
      Dim be As Encoding = New UnicodeEncoding(True, True)

      ' Get a UTF-8 encoding by name.
      Dim e8 As Encoding = Encoding.GetEncoding("utf-8")

      ' Check equality of e16_1 and e16_2.

' This example produces the following output.
'       utf-16 equals utf-16? True
'       utf-16 equals utf-16? True
'       utf-16 equals utf16BE? False
'       utf-16 equals utf8? False
