Encoding.Convert Method (Encoding, Encoding, array<Byte[])

Parameters

• srcEncoding
  Type: System.Text.Encoding
  The encoding format of bytes.

• dstEncoding
  Type: System.Text.Encoding
  The target encoding format.

• bytes
  Type: array<System.Byte[]
  The bytes to convert.

Return Value

Type: array<System.Byte[]
A byte array that contains the results of converting bytes from srcEncoding to dstEncoding.

Imports System.Text

Class Example
   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim unicodeString As String = "This string contains the unicode character Pi(" & ChrW(&H3A0) & ")"

      ' Create two different encodings.
      Dim utf8 As Encoding = Encoding.UTF8
      Dim unicode As Encoding = Encoding.Unicode

      ' Convert the string into a byte[].
      Dim unicodeBytes As Byte() = unicode.GetBytes(unicodeString)

      ' Perform the conversion from one encoding to the other.
      Dim utf8Bytes As Byte() = Encoding.Convert(unicode, utf8, unicodeBytes)

      ' Convert the new byte[] into a char[] and then into a string.

      utf8.GetChars(utf8Bytes, 0, utf8Bytes.Length, utf8Chars, 0)
      Dim utf8String As New String(utf8Chars)

      ' Display the strings created before and after the conversion.
      outputBlock.Text += String.Format("Original string: {0}", unicodeString) & vbCrLf
      outputBlock.Text += String.Format("Ascii converted string: {0}", utf8String) & vbCrLf
