Question

Answer 1

A general solution like this (to instantiate a type with a generic parameter based on a System.Type object) is not possible. If you're really just dealing with these three types, though, then you're in luck because it's pretty easy:

Type t = typeof(obj);

if (t == typeof(List)) {
    var contactList = (List)obj;
    // do stuff with contactList

} else if (t == typeof(List
)) {
    var addressList = (List
)obj;
    // do stuff with addressList

} else if (t == typeof(List)) {
    var documentList = (List)obj;
    // do stuff with documentList
}
