We created a unicode file using java application. It usesmethods like writeUTF(), writeInt() of java.io.DataOut putStreamclass to write the content of the file. We are able to read datausing java.io.DataInp utStream.readUT F() method. It's workingwell in java environment.
When we tried to read the above unicode file in .net environment.We received junk content not the original content.
Actually we tried a sample program in c# and usedSystem.Text .UTF8Encoding(t rue) option also. Any help highlyappreciat ed.

writeUTF first writes a pair of bytes to give the number of bytes to
follow. Those aren't UTF-8 characters, but .NET would be expecting them
to be.
Effectively, writeUTF and readUTF are only designed to work with
DataInputStream/DataOutputStrea m. You can probably read that pair of
bytes before reading the rest, but it's not ideal. If you're just
creating a text file in Java, I suggest you use OutputStreamWri ter
wrapped round a FileStream, and specify UTF-8 as the encoding. If
you're writing a file with mixed binary and text data, you need to make
sure you know *exactly* what you're writing, and then read it very
carefully from the other platform.

Hello, Sivaraj!
Here is a block of code that might help (or give some ideas),
if I understood you correctly:
string
s=string.Empty,
path="c:\file.t xt", //... or whatever file you'll be using
NewLine=string. Empty; //this variable doesn't have to be initialized, but
it is a good habit
System.IO.Strea mReader MyStreamReader=
new System.IO.Strea mReader(path, System.Text.Enc oding.UTF8);
while((NewLine= MyStreamReader. ReadLine())!=nu ll)
s+=NewLine+"\r\ n";
MyStreamReader. Close();
//Now do something with 's'
Regards

I disagree on that point - if an assignment isn't required because
there'll be another assignment before the first "read" of the variable,
I'd rather the extraneous assignment isn't present in the first place.
It implies that the assigned value has some purpose, when it doesn't.
System.IO.Strea mReader MyStreamReader= new System.IO.Strea mReader(path, System.Text.Enc oding.UTF8);
while((NewLine= MyStreamReader. ReadLine())!=nu ll) s+=NewLine+"\r\ n";
That's a horrible way of building up a string. Use StringBuilder
instead.
In this case though, just MyStreamReader. ReadToEnd() would be a better
solution still.
MyStreamReader. Close();
You should use a using statement instead - that way if an exception is
thrown, the StreamReader still gets disposed.
