How can I use C # to fetch Java data from a socket?

I want to send data BigInteger

to a socket and my friend wants to receive data.
I am using Java, but my friend is using C #.

String str = "Hello";
BigInteger big = new BigInteger(str.getBytes);
byteToBeSent[] = big.toByteArray();

I am sending this byte array ( byteToBeSent[]

) over a socket. And my friend wants to receive "Hello".

How is this possible?

From Java, send your string using String.getBytes (encoding) and provide an encoding that matches how your friend will read it (like UTF-8).

This will translate your string into a stream of bytes, which will translate to the end of C # due to the fact that you both agree on the encoding mechanism.



I'm not sure what your BigInteger mechanism is doing, but I don't believe it will be portable and doesn't handle meaningful strings.

Honestly, it's best to use the built-in coding classes in C #.

string str = "Hello";
byte[] data = System.Text.Encoding.UTF8.GetBytes(str);


And then send that over the socket.

Why are you using BigInteger

String to send data? Or is this just an example?

If you want to send String data, use String.getBytes(String encoding)

, send the result and decode it with System.Text.Encoding

.

You will need a custom BigInteger class for C # .

But parsing "Hello" as a big integrator won't work. I want to send text, it is better to use Navaars method.

At the end of C #, you can use System.Text.Encoding.ASCII.GetString (bytesToConvert []) to convert the resulting byte array to a string.

I thought it was some Java idiot for converting a string to a byte array. It will correctly convert the string to ASCII bytes, and since the length of the BigInteger is arbitrary, the length of the string shouldn't be an issue.
