Public Overridable ReadOnly Property CurrentEncoding As Encoding

Property Value

Type: System.Text.Encoding

The current character encoding used by the current reader. The value can be different after the first call to any Read method of StreamReader, since encoding autodetection is not done until the first call to a Read method.

For a list of common I/O tasks, see Common I/O Tasks.

The following code example gets the encoding of the specified StreamReader object.

Public Class Test

    Public Shared Sub Main()
        Dim path As String = "c:\temp\MyTest.txt"
        Try
            If File.Exists(path) Then
                File.Delete(path)
            End If

            'Use an encoding other than the default (UTF8).
            Dim sw As StreamWriter = New StreamWriter(path, False, New UnicodeEncoding())
            sw.WriteLine("This")
            sw.WriteLine("is some text")
            sw.WriteLine("to test")
            sw.WriteLine("Reading")
            sw.Close()

            Dim sr As StreamReader = New StreamReader(path, True)

            Do While sr.Peek() >= 0
                Console.Write(Convert.ToChar(sr.Read()))
            Loop

            'Test for the encoding after reading, or at least
            'after the first read.
            Console.WriteLine("The encoding used was {0}.", sr.CurrentEncoding)
            Console.WriteLine()

            sr.Close()
        Catch e As Exception
            Console.WriteLine("The process failed: {0}", e.ToString())
        End Try
    End Sub
