while loop causing a deadlock

goo hey

im using a do , while (true loop) and with the setup my code is getting stuck reading the loop continously would a break option work befroe the code reads ERROR: no entries found??

if (!reply.EndsWith("404 Not Found"))

                            {
                                string line1 = sr.ReadLine();
                                 //line1 = sr.ReadLine();

                                try
                                {
                                    do
                                    {
                                        line1 = sr.ReadLine();

                                    } while (line1 != "");

                                }
                                catch { }

                                Console.WriteLine(username + " is " + sr.ReadLine());
                                try
                                {
                                    while (true)
                                    {
                                        Console.WriteLine(sr.ReadLine());

                                    }
                                }
                                catch { }

                            }

                            else
                            {
                            Console.WriteLine("ERROR: no entries found");
                            }

If you use break then it will get out from the loop. If you are getting stuck in the loop means may be while condition is true. You can check with putting debugger. Thanks

hey thatnks for the reply , i worded that question wrong iam indeed getting the right output meaning the while condition is true but instead of the program to continue its getting stuck which im guessing is caused by the loop going over again and wondering if use break and where to use it would it work?

Hey.
break is used to exit from the loop. The real usage of break you can read here,

https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/do

If you are going out of the loop means either the while condition false inside the do while loop.
And as you said about ERROR: no entries found this line means it is directly hitting to the else condition means your if condition is not true.

For more you can simply put breakpoint and check.

If it helps mark as answer.
Thanks.
