Sending Generic Object

[ADN]

Hi, I have a method which calls my service factory:

class person
{
public int ID { get; set: }
public string Name {get; set;}
}

IList<Personmypeople = __serviceFactory.Fetch(new Person())

Here is my generic method:

public List<TFetch<T>(T fetchobject)
{
Type __type = fetchobject.GetType();

// return a generic list of all of the people
IList<__typemyPeopleList = new IList<__type>();

myPeopleList = DataLayer.GetMyPeople(); // will return a
IList<Person>

return myPeopleList
}

I am getting an error when I try to cast the IList<typebecause I
don't think you can do that. Is there a way I can pass in a generic
object and create a generic collection from a generic object?

Or...
public List<TFetch<T>()
{
return (List<T>)DataLayer.GetMyPeople();
}

myPeopleList = DataLayer.GetMyPeople(); // will return a
IList<Person>

return myPeopleList
}

You cannot pass Type values as generic parameters. But in your case, I
do not see why you'd even need to. First of all, would you be okay
with this?

public List<TFetch<T>(T fetchobject)
{
// return a generic list of all of the people
IList<TmyPeopleList = new IList<T>();
...
}

This doesn't use the actual run-time type of the passed object, but
rather the type of expression that was passed as an argument.

The second problem is that your generic method is not really generic -
here's why:

myPeopleList = DataLayer.GetMyPeople(); // will return a
IList<Person>

Well, if it can only handle lists of Person, then why are you trying
to make it generic in the first place?
