How to pass data to a thread on runtime in c#

C#

I have a function :

static void fun1(string req)
      {
          while (true)
          {
              if (req == "read")
                  Console.WriteLine(req);
              else
                  Console.WriteLine(req);

          }
      }

to this function i want to pass an argument on runtime. This function will be mapped with a thread.

- This means that i will be passing data to the thread.
- I want to try out a scenario... on user input i want to pass an argument to the thread during runtime.
- How to achieve this? I tried out something like this:


Thread t = new Thread(() => fun1("hello"));

- I have used a lambda expression to pass data.
- Now i will start the thread:
t.Start();
- This thread now runs in the background. Now in the main function i will ask the user to enter some data lets say "Hey".
- So now the thread in the background should print "Hey" on the console on user input. So how to achieve this?
- Say for example in the main i say something like this :


console.writeline("Enter some thing");
string data = console.readline();

/////please note that the thread is running in the background///////
/////Now how to pass the data to the thread????

- I created an empty constructor of the class and started the thread.
- In the main i instantiate the constructor.
- Now the program hangs.


Thanks
Please guide.
