Get return value of method in parallel execution

Question

I am using Parallel.Invoke to execute single method with different input values, but I want to get return value of the method. How can I get it ?

public class Work
{
    public static void Main()
    {
        Parallel.Invoke(() => DoWork("Raju"),
                        () => DoWork("Ramu"));
    }

    public static string DoWork(string data)
    {
        return "testing" + data;
    }
}

In above method I want get DoWork return value.

Answer 1

Just handle the return value like this:

string result1, result2;

Parallel.Invoke(() => result1 = DoWork("Raju"),
                () => result2 = DoWork("Ramu"));

Also remember that whenever you do something in parallel you need to be careful to avoid data races and race conditions.
