Question

I have a MyFunction that may take several datatypes, which are all very similar. I just want to pass all these different types of data into MyFunction with multithreading and type cast in MyFunction. Is this something possible? Is using dictionary a good idea? Please advise.

Main(){
    Parallel.ForEach(objectType1, MyFunction)
    Parallel.ForEach(objectType2, MyFunction)
    Parallel.ForEach(objectType3, MyFunction)
}

MyFunction(object arg){
  Dictionary<string, object> d = (Dictionary<string, object>) arg;
  Type1 t1;
  Type2 t2;
  Type3 t3;
  if (d.Key == "Type1") {
        t1 = (Type1) d.Value;
        ProcessType1(t1);
  }
  else if (d.Key == "Type2") {
    t2 = (Type2) d.Value;
        ProcessType2(t2);
  }
  else if (d.Key == "Type3") {
    t3 = (Type3) d.Value;    
        ProcessType3(t3);
  }

}

You could do:

MyFunction (object arg) {
    if (arg is Type1) { ProcessType1(arg as Type1); }

    else if (arg is Type2) { ProcessType2(arg as Type2); }

    else if (arg is Type3) { ProcessType3(arg as Type3); }
}
