I am trying to loop through a directory and 开发者_如何学运维for ever text file that I find, convert the encoding to UTF-8 Fromat.

Use DirectoryInfo and you're pretty much done

DirectoryInfo DI = new DirectoryInfo("TextFiles_Path");
FileInfo[] Files = DI.GetFiles("*.txt");
foreach(FileInfo Fl in Files)
{
    StreamReader SR = Fl.OpenText(); //This opens a stream to the file **in UTF8 encoding**
    StreamWriter SW = new StreamWriter(new FileStream(Fl.FullName + ".UTF8.txt", FileMode.OpenOrCreate), Encoding.UTF8);
    SW.Write(SR.ReadToEnd());
}

Enjoy

Fast and easy

For Each oFile In IO.Directory.GetFiles(dir, "*.*", IO.SearchOption.AllDirectories)
    IO.File.WriteAllText(oFile, IO.File.ReadAllText(oFile), Encoding.UTF8)
