how you would create a “Pair†class that uses generics to group an unrelated
pair of classes such that it would be instantiated as:
Pair<MyClass1, MyClass2> pair = new Pair<MyClass1, MyClass2>(first,
second);


Thanks

You can simply set "first" and "second" by means of the constructor,
unless I am completely misunderstanding what you really want.

public class Pair<T1, T2>
{
public T1 First { get; set; }
public T2 Second { get; set; }

public Pair<T1, T2>(T1 first, T2 second)
{
First = first;
Second = second;
}
}

Thank you very much!
I am just now learning Generics and came across this question.
Thanks again.

System.Collection.Generic defines class KeyValuePair<KeyType,
ValueType>. It is used on key based collections like
SortedDictionary<KeyType, ValueType> and SortedList<KeyType, ValueType>
to add or fetch key/value pairs. I don't know if there is any restict on
the KeyType, i.e. can you use your MyClass1.

Since KeyValuePair.Key and KeyValuePar.Value are readonly properties
it may not meet his requirements.
