dynamic Getvalue return object cast to PropertyInfo.PropertyType

My question is: How can make 

PropertyInfo.GetValue(object, null);

return value with casted to PropertyType, not return object.

I tried Convert.ChangeType but not luck.

Thank you.

Update 1:

More detail:

My code:

foreach (var propertyInfo in customerInfo.CustomerRelationship.GetType().GetProperties())
{
    var relationshipList = (IList)propertyInfo.GetValue(customerInfo.CustomerRelationship, null);
    foreach (var relationship in relationshipList)
    {
    }
}

with 

public struct CustomerInfo
{
    public Customer CustomerItem { get; set; }
    public Relationship CustomerRelationship { get; set; }
}

public class Relationship
{
    public List<Contact> ContactItems { get; set; }
    public List<Department> DepartmentItems { get; set; }
    ..........
}

Because i can't dynamic cast each Relationship Item show i can't compare, query (Linq) manipulate with database .

You can't.

For the sake of simplicity, a generic wrapper can be written over it.

public static T GetValue<T>(Object obj1, Object obj2)
{
return (T)PropertyInfo.GetValue(obj1, obj2);
}
