ایجاد یک فایل با فورمت UTF8 بر روی سرور

دوست عزیز در مورد کلاس IO.TextWriter تحقیق کنید این هم یک مثال از msdn

Imports System

Imports System.IO



Public Class TextRW



    Shared Sub Main()

        Dim aStringWriter, aStreamWriter As TextWriter

        aStringWriter = New StringWriter()

        aStreamWriter = New StreamWriter("InvalidPathChars.txt")

        

        WriteText(aStringWriter)

        WriteText(aStreamWriter)

        aStreamWriter.Close()

        

        Dim aStringReader, aStreamReader As TextReader

        aStringReader = New StringReader(aStringWriter.ToString())

        aStreamReader = New StreamReader("InvalidPathChars.txt")

        

        ReadText(aStringReader)

        ReadText(aStreamReader)

        aStreamReader.Close()

    End Sub



    Shared Sub WriteText(aTextWriter As TextWriter)

        aTextWriter.Write("Invalid file path characters are: ")

        aTextWriter.Write(Path.InvalidPathChars)

        aTextWriter.Write("."C)

    End Sub



    Shared Sub ReadText(aTextReader As TextReader)

        Console.WriteLine("From {0} - {1}", _

            aTextReader.GetType().Name, aTextReader.ReadToEnd())

    End Sub



End Class
