.NET Forum / .NET Framework / New Users / March 2006C# ASP .NET -- UTF-16 encoding to UTF-8
I have a web application written in ASP .NET (VS 2003) which an Adobe Acrobat Form posts XML to. I am able to get the XML using the Request.InputStream however the XML is UTF-16 encoded. This means that the byte[] that i get from the Request.InputStream looks like: [0]: 255 [1]: 254 [2]: 64 [3]: 0 [4]: 56 [5]: 0 ... essentially every other index in the array holds the value 0. When i try to convert the byte array to a string, i get <\0x\0\m\0l\0 .. (every other character is a \0) .. I also have the '\r\n' character before the ending tags in the xml. my question is two fold 1) how can i elegantly convert the UTF-16 formated xml to something more readable aka UTF-8, ASCII, etc in Visual Studio 2003 (i cant find any UTF-16 encoding support in VS 2003) 2) If 1 doesnt get rid of the '\r\n's how can i get rid of them? string.replace("\r\n", "") didnt seem to work. Thanks http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlr fSystemTextUnicodeEncodingClassTopic.asp use the GetString() method ... then if you want it in UTF 8 you can use http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlr fSystemTextUTF8EncodingClassTopic.asp to convert it.

My scope has slightly changed -- i no longer need UTF-8 encoding persay, just need to parse the values from the XML that is being sent over, so i need to convert the byte[] to a readable string. .. here is my code: ------------------------------------- Request.InputStream.Read(data, 0, Convert.ToInt32(Request.InputStream.Length)); UnicodeEncoding encoding = new UnicodeEncoding( ); string decodedString = encoding.GetString(characters); //at this point decodedString = " ????? ??????????? ? ?????????????????????????????????????????????????????????????????????????????????????????????????????????????" DataSet ds = new DataSet(); ds = XmlToDataSet(decodedString); ------------------------------------- when decodedString is passed to XmlToDataSet, it crashes I assume because XmlToDataSet does not look like the encoding on the decodedString.. How do i get the byte[] the Request.InputStream yields into a "normal" encoding? Thanks Thus wrote davidjgonzalez@gmail.com, > Greg thanks for the reply but that didn't seem to work.. > [quoted text clipped - 15 lines] > ?????????????????????????????????????????????????????????????????????? > ???????????????????????????????????????" Your code is not really complete. You're reading into a byte array "data", but decode something called "characters". Note that you don't really need to perform these steps yourself, if all you want to do is fill a DataSet. aDataSet.ReadXml(Request.InputStream); should do the trick. The XML infrastructure can figure out the encoding by itself. Cheers,  SignatureJoerg Jooss news-reply@joergjooss.de oop - thanks for the catch .. string decodedString = encoding.GetString(characters); is supposed to read string decodedString = encoding.GetString(data); your ReadXml(...) solution from the input stream is just what i needed! thanks
