How to call the method in thread with arguments and return some value

Question

I like to call the method in thread with arguments and return some value here example

class Program
{
    static void Main()
    {
        Thread FirstThread

For some alternatives; currying:

static ThreadStart CurryForFun(int i, int j)
{ // also needs a target object if Fun1 not static
    return () => Fun1(i, j);
}

Thread FirstThread = new Thread(CurryForFun(5, 12));

or write your own capture-type (this is broadly comparable to what the compiler does for you when you use anon-methods / lambdas with captured variables, but has been implemented differently):

class MyCaptureClass
{
    private readonly int i, j;
    int? result;
    // only available after execution
    public int Result { get { return result.Value; } }
    public MyCaptureClass(int i, int j)
    {
        this.i = i;
        this.j = j;
    }
    public void Invoke()
    { // will also need a target object if Fun1 isn't static
        result = Fun1(i, j);
    }
}
...
MyCaptureClass capture = new MyCaptureClass(5, 12);
Thread FirstThread = new Thread(capture.Invoke);
// then in the future, access capture.Result
