Question

My C# function returns 100 list objects at a time. I want to fill a list until this function does not return any lists.

I am trying to do something like this:

int lastSelectedId = 0;
while(ReturnListOfCustomers(lastSelectedId).Count > 0)
{
    List<Customers> newCustomers = ReturnListOfCustomers(lastSelectedId);
    CustomerList.Append(newCustomers);
    lastSelectedId  = newCustomers.Last().rowid;
}

…but in this case I will have to call ReturnListOfCustomers function twice per loop,
can I make it better by calling it one at a time?

Thanks.

You can use do/while

int lastSelectedId = 0;
int count;
do 
{
    List<Customers> newCustomers = ReturnListOfCustomers(lastSelectedId);
    count = newCustomers.Count;
    if (count > 0)
    {
        CustomerList.Append(newCustomers);
        lastSelectedId  = newCustomers.Last().rowid;
    }
} while (count > 0);
