buffer = sr.ReadLine().ToCharArray())!=null

examenca

Hi I have a Char buffer = new Char[1024] and i'm using StreamReader sr to read from a NetWorkStream. when launching the app it gives me an error at the end. while((buffer = sr.ReadLine().ToCharArray())!=null) { Console.WriteLine(buffer); } So basically i'm trying to print the information that is i'm receiving through the socket. Please help! Thanx.

also the line (if it was a valid line of code :) ) buffer = sr.ReadLine().ToCharArray())!=null will only store a boolean value in the buffer variable as a result of the comparison.

Hi I assume, that the code above throws a NullReferenceException. This is because sr.ReadLine() returns null to tell you that the end was reached. So, if this happens, sr.ReadLine().ToCharArray() will try to access null (with ToCharArray()). And then you get the exception. Try this: string str = null; while((str = sr.ReadLine()) != null) { buffer = str.ToCharArray() Console.WriteLine(buffer); } Now, you should have any errors. Simon
