Wait for value to not be null until thread finishes
Hey, how can I start a thread and wait until a string is not null/empty to return it?
I'm calling a static string from another class, this starts a new thread that gets the response from the server and assigns it to a string. The problem is that the answer is returned before the thread does its job. I've thought about coroutines but I don't see a way of returning values directly.
If anyone has any tips on how this should be done or any methods to follow I'm all ears.
Here's the code:
private static Thread sendAndReceiveDataThread;
private static Networking Instance;
private void Awake()
{
Instance = this;
}
private static string answer;
public static string SendAndReceive(string data)
{
sendAndReceiveDataThread = new Thread(() => Instance.SendAndReceiveData(data));
sendAndReceiveDataThread.Start();
return answer;
}
private void SendAndReceiveData(string data)
{
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] bytes = encoding.GetBytes(data);
WebRequest request = WebRequest.Create(server);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytes.Length;
Stream stream = request.GetRequestStream();
stream.Write(bytes, 0, bytes.Length);
stream.Close();
WebResponse response = request.GetResponse();
stream = response.GetResponseStream();
StreamReader sr = new StreamReader(stream);
answer = sr.ReadToEnd();
stream.Close();
sr.Close();
request.Abort();
sendAndReceiveDataThread.Abort();
}
