Write error on Read() ??

P: n/a
I'm writing a console app in c# and am encountering a strange problem. I'm
trying to use redirection of the standard input stream to read input from a
(xml) file. The following code snippet is from this app:
===============================
static void Main(string[] args)
{
if (args.Length > 0) Console.SetIn(new StreamReader(args[0]));
//executes if I don't use the "<", ">" redirection syntax when invoking

XmlTextReader xmlin = new XmlTextReader(Console.In);
xmlin.WhitespaceHandling = WhitespaceHandling.None;

if (args.Length > 1) Console.SetOut(new
StreamWriter(args[1]));//executes if I don't use the "<", ">" redirection
syntax when invoking

XmlTextWriter xmlw = new XmlTextWriter(Console.Out);
string SchemaResource = "DBDumper.DumpSpec0.xsd";
XmlValidatingReader xmlvr = new XmlValidatingReader(xmlin);
Assembly a = Assembly.GetExecutingAssembly();
Debug.Assert (a.GetManifestResourceInfo(SchemaResource) != null);
XmlTextReader xsdreader = new XmlTextReader(new
StreamReader(a.GetManifestResourceStream(SchemaRes ource)));
xmlvr.Schemas.Add(null, xsdreader);
try
{
xmlvr.Read();
....
=============================
So, assuming my app's executable is foo.exe, things work fine if I type in

foo input.xml output.xml

Also,
foo input.xml > output.xml

works fine. But, if I type in:

foo < input.xml > output.xml

I get an error on the xmlvr.Read() in the last line above, complaining that
the stream does not support a Write!!

Can anyone give me help on this? I've stared at it now for a while and don't
see the problem.

Thanks in advance,
Bill

Hi Bill,

I can not reproduce the problem, here is my code , you may have a try.
Did I misunderstand your meaning?
Can you please post the exactly error messge?

Peter-
Thanks for the response. I'll try your code to see if I can figure out
the difference. In the meantime, did you try this using the redirection
symbols ">" and "<"? That's how I got the error.

Bill

Peter-
I've figured out the problem. In my case the XML file in question was
written using UTF-8 encoding -- which apparently includes some binary
"chars" at the beginning of the file. If I remove those characters then my
use of Console.In to create an xmltextreader works as expected. So, the
problem was pilot error; although I think the "Write error on Read()" error
was certainly a misleading one!

Thanks again for the response,
Bill

Hi Bill,

I have tried to use the redirection symbols ">" and "<" in my demo code.
I am glad that the problem has been resolved.
