About FileStream and StreamWriter!?



I have a string1 which contains(of course in unicode) a html code with
Unicode charset specified in it.

1)

byte[]content= System.Text.UnicodeEncoding.Unicode.GetBytes(string1);

System.IO.FileStream wr=new System.IO.FileStream("C:\\myhtml.html"
,System.IO.FileMode.CreateNew);

wr.Write(content,0,content.Length);

wr.Close();



When I opened the file some characters are unreadable, so something is wrong
in my code above, but then I have done:

2)

byte[]content= System.Text.UnicodeEncoding.Unicode.GetBytes(string1);

//System.IO.FileStream wr=new //System.IO.FileStream("C:\\myhtml.html"
,System.IO.FileMode.CreateNew);

//wr.Write(content,0,content.Length);

//wr.Close();



System.IO.StreamWriter tr=new System.IO.StreamWriter("C:\\myhtml.html"
,,false,System.Text.Encoding.Unicode);

string teststr=System.Text.Encoding.Unicode.GetString(content);

tr.Write(teststr);//(I did not simply used string1 in it because of reason
of testing)



And file was in good form, why first time wasn't good as second?



Tanks to all!

I have a string1 which contains(of course in unicode) a html code with
Unicode charset specified in it.

1)

byte[]content= System.Text.UnicodeEncoding.Unicode.GetBytes(string1);

Note that UnicodeEncoding.Unicode is more canonically known as just
Encoding.Unicode.

System.IO.FileStream wr=new System.IO.FileStream("C:\\myhtml.html"
,System.IO.FileMode.CreateNew);

wr.Write(content,0,content.Length);

wr.Close();

No, that's not necessarily the case. Are you sure the editor you're
opening the file with can copy with the UCS-2 encoding?

but then I have done:

2)

byte[]content= System.Text.UnicodeEncoding.Unicode.GetBytes(string1);

//System.IO.FileStream wr=new //System.IO.FileStream("C:\\myhtml.html"
,System.IO.FileMode.CreateNew);

//wr.Write(content,0,content.Length);

//wr.Close();

System.IO.StreamWriter tr=new System.IO.StreamWriter("C:\\myhtml.html"
,,false,System.Text.Encoding.Unicode);

string teststr=System.Text.Encoding.Unicode.GetString(content);

tr.Write(teststr);//(I did not simply used string1 in it because of reason
of testing)

The first probably didn't emit a byte order mark (BOM) whereas the
second one might have done. I suggest you look at the difference with a
binary file editor. If I'm write, the second file will have the bytes
0xFF 0xFE (or 0xFE 0xFF - I can never remember the order off-hand) at
the start, whereas the first won't.
