1.) I have a main method Processing, which takes string as an arguments and that string contains some x number of tasks.

2.) I have another method Status, which keeps track of first method by using two variables TotalTests and CurrentTest. which will be modified every time with in a loop in first method(Processing).

3.) When more than one client makes a call parallely to my web service to call the Processing method by passing a string, which has different tasks will take more time to process. so in the mean while clients will be using a second thread to call the Status method in the webservice to get the status of the first method.

4.) when point number 3 is being done all the clients are supposed to get the variables(TotalTests,CurrentTest) parallely with out being mixed up with other client requests.

5.) The code that i have provided below is getting mixed up variables results for all the clients when i make them as static. If i remove static for the variables then clients are just getting all 0's for these 2 variables and i am unable to fix it. Please take a look at the below code.

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
public class Service1 : IService1
{
    public int TotalTests = 0;
    public int CurrentTest = 0;

    public string Processing(string OriginalXmlString)
    {
                XmlDocument XmlDoc = new XmlDocument();
                XmlDoc.LoadXml(OriginalXmlString);
                this.TotalTests = XmlDoc.GetElementsByTagName("TestScenario").Count;  //finding the count of total test scenarios in the given xml string
                this.CurrentTest = 0;
                while(i<10)
                {
                        ++this.CurrentTest;
                         i++;
                }
    }

    public string Status()
    {
        return (this.TotalTests + ";" + this.CurrentTest);
    }
}

Below mentioned is my client code

class Program
{
static void Main(string[] args)
{
    Program prog = new Program();
    Thread JavaClientCallThread = new Thread(new ThreadStart(prog.ClientCallThreadRun));
    Thread JavaStatusCallThread = new Thread(new ThreadStart(prog.StatusCallThreadRun));
    JavaClientCallThread.Start();
    JavaStatusCallThread.Start();
}

public void ClientCallThreadRun()
{
    XmlDocument doc = new XmlDocument();
    doc.Load(@"D:\t72CalculateReasonableWithdrawal_Input.xml");
    bool error = false;
    Service1Client Client = new Service1Client();
    string temp = Client.Processing(doc.OuterXml, ref error);
}

public void StatusCallThreadRun()
{
    int i = 0;
    Service1Client Client = new Service1Client();
    string temp;
    while (i < 10)
    {
        temp = Client.Status();
        Thread.Sleep(1500);
        Console.WriteLine("TotalTestScenarios;CurrentTestCase = {0}", temp);
        i++;
    }
}
}

Can any one please help.
