文件系统观察器以选择和转换XML编码

Question

I'm using the filesystem watcher to pick and convert the encoding of a file, the file gets copied at the destination but without conversion. I was using the below code earlier:

 string xml = File.ReadAllText(FileName,ansi);
        XDocument xmlDoc = XDocument.Parse(xml);
             Console.WriteLine("1st");
              File.WriteAllText(
                 FileName,
                  @"<?xml version=""1.0"" encoding=""utf-8""?>" +  xml.ToString(),
                   utf8
               );


             if (File.Exists(destinationFile))
                    File.Delete(destinationFile);
                File.Copy(FileName, destinationFile,true);
                Console.WriteLine("File Copied" + "  " + DateTime.Now.ToString("HH:mm:ss tt")); // for troubleshoooting only
                Console.WriteLine("Press \'q\' to quit."); 
                Console.Write(CrL);

But this is not working now , as the xml file I'm getting now contains the following header:

  <?xml version="1.0" encoding="WINDOWS-1256"?>

I was earlier suggested the below code:

var doc = new XmlDocument();
doc.Load(FileName);

XmlWriterSettings settings = new XmlWriterSettings { Encoding = Encoding.UTF8, Indent=true };

 using (var fileStream = File.OpenWrite(destinationFile))
{
 using (var writer = XmlWriter.Create(fileStream, settings))
 {

    doc.Save(writer);
  }
} 

But this is not doing the conversion at all. The dest. file is still ansi. It's not doing the conversion to utf8. Am I doing something wrong here

Answer 1

You're rewriting the output file (the file written by XmlWriter ) with the original one by this code:

if (File.Exists(destinationFile))
    File.Delete(destinationFile);
File.Copy(fileName, destinationFile, true);

Just remove these lines of code.

Update

Writing the XML-document using Windows-1256 encoding:

var settings = new XmlWriterSettings
    {
        Encoding = Encoding.GetEncoding("windows-1256"),
        Indent = true
    };
