I have a text file with wide characters. I use the following C++ code to read
them in. However the wide characters are read in properly. What is wrong?
String* path = "C:\\Docume nts and Settings\\kst\\ BE.dat";
try
{
FileStream* fs = new FileStream(path , FileMode::Open) ;
StreamReader* sr = new StreamReader(fs );
int count = 0;
while (sr->Peek() >= 0)
{
count++;
Debug::Write(__ box(count));
Debug::WriteLin e(__box((Char)s r->Read()), " ");
}
} 7 4793
"are read in properly" should be "are not read in properly" in the following
description.

Well, what encoding is used for the text file? The default for
StreamReader is UTF-8. If that isn't the encoding used for your file,
you'll get the wrong characters. You really need to know what the
encoding is.
See http://www.pobox.com/~skeet/csharp/unicode.html for more
information.

Thank you for replying.
It is a text file contains both Ascii (one byte) and Chinese characters (two
bytes) coded in big-5. How do I find the encoding of a text file?

You need to know the encoding - a text file is just a bunch of bytes,
the same as any other file. It's the interpretation which matters.
That sounds like it's just a Big-5 file though - as far as I can see,
ASCII characters come out the same in Big-5.
Big-5 is Windows codepage 950, I believe, so use
Encoding.GetEnc oding(950).

Thank you very much for your help.
I try Encoding.GetEnc oding("big5") and it works.

Sorry to post this, I feel like a right fool but Im under serious time

Any ideas how to get this working?

I have a WCHAR array (say WCHAR *wszName). I want to convert it to wstring. So, I do the following:-
wstring wstrName(wszName);
It works. But I want to know what internally happens when the conversion takes place. For example, does it allocate some new buffer? While debugging an application, I looked into the code of the conversion, but could not understand it. Could you please post the code of conversion and explain it to me?
Thanks.
