do i need dispose ephemeral disposable objects?

i have category creates several idisposable objects, objects following upheld another 'manager' category 3rd jubilee library. i need objects after calls i kept internal domain anxiety combined objects i opening during after time. i ran fxcop category conspicuous i should exercise idisposable, due disposable objects i kept anxiety to. questions are:

1. should i exercise idisposable class? (or manager's responsibility?)


2. if so, should i wholly dispose objects i kept anxiety to? should i proceed dispose objects i created.

my code:

public category myclass  
{  
    classthatisdisposable areference;  
}

public myclass(managerclass manager)  
{  
    classthatisdisposable transient=new classthatisdisposable();  
    manager.add(transient);  
    areference=new classthatisdisposable();  
    manager.add(areference);  
}

public vacant latercall()  
{  
    areference.method();  
}
