Question

I’m wanting to create a generic lookup method to where you specify a type of object and some other identifying parameters and the method returns an object of that type. Is this possible?

I’m thinking something like this.

public T GetObjectOfType(Guid ID, typeof(T Class))
{
     //lookup this object and return it as type safe
}

I know this just won’t work but i hope it explains the concept

You can use a generic method for this:

public T GetObjectOfType<T>(Guid id) where T: class, new()
{
    if (id == FooGuid) //some known identifier
    {
        T t= new T(); //create new or look up existing object here
        //set some other properties based on id?
        return t;
    }
    return null;
}

If all you want is create an instance of a specific type you do not need the additional id parameter, I assume you want to set some properties etc. based on the id. Also your class must provide a default constructor, hence the new() constraint.
