Question

I am in .net 2.0 .
I am looking for a smart fast way to merge two hash tables. For now i am doing it like

foreach (string id in  _unValidatedMachine)
{
       _Machine.Add(id, _unValidatedMachine[id]);
} 


_unValidatedMachine.Clear();

I even not check here the inserted hash for existing of the key , probably i should do it .

Any ideas how to do the merge ?

Answer 1

There is not a standard way to join two Hashtables.

Yes, you should check if the key is already added, in other case you could get an exception.

Also you could use:

_Machine[id] = _unValidatedMachine[id]; 

In this case, if the key exists, you will only overwrite its value.
