Question

What I need to do is get foreach values from one method called private void ReceiveData() and send them to another method void Update() . How to do that in c#?

private void ReceiveData() 
    {

       IPEndPoint remoteIP = new IPEndPoint(IPAddress.Parse("10.0.2.217"), port);
       client = new UdpClient(remoteIP);
        while (true) 
        {
           try 
            {
                IPEndPoint anyIP = new IPEndPoint(IPAddress.Any, 0);
                data = client.Receive(ref anyIP);

                int nIndex = 0;
                foreach(SignalIndex si in xmlreader.cdpSignals)
                {
                     x= ReadSingleBigEndian(data, si.index + 0);
                     y= ReadSingleBigEndian(data, si.index + 4);
                     z= ReadSingleBigEndian(data, si.index + 8);
                     alpha= ReadSingleBigEndian(data, si.index + 12);
                     theta= ReadSingleBigEndian(data, si.index + 16);
                     phi= ReadSingleBigEndian(data, si.index + 20);

                //  xmlreader.unityGameObjects[nIndex].transform.localPosition = new Vector3(x,y,z);
                //  xmlreader.unityGameObjects[nIndex].transform.Rotate(alpha,theta,phi);   
                }

            }
            catch (Exception err) 
            {
               print(err.ToString());
            }

        }

        client.Close();
    }


    void Update() 
    {
        foreach(GameObject go in xmlreader.unityGameObjects)
        {
            go.transform.localPosition = new Vector3(x,y,z);
            go.transform.transform.Rotate(alpha,theta,phi);
        }
    }

There are 2 methods and I need to get the values in foreach from ReceiveData() and instantiate them in method Update(). All variables in foreach from ReceiveData() are public, but they all takes 0 in Update().

Documentation for ReaderWriterLockSlim: http://msdn.microsoft.com/en-us/library/system.threading.readerwriterlockslim.aspx

struct CoordData

                 nIndex++; //I'm assuming you want to do this here otherwise you'll be changing the same object in the array every time  
            }

        }
        catch (Exception err)

    finally
