Hi,

In the first chapter there is a metho with the signture
Public Shared Function GetContactsByFirstLetterAsCollection(ByVal DiaryId As Integer, Optional ByVal FirstLetterOfSurname As Char = "*") As ContactCollection

There is no such a behavior in C# so I have written
public static ContactCollection GetContactsByFirstLetterAsCollection(int diaryId, char FirstLetterOfSurname)
    {
        if (FirstLetterOfSurname == 0)
            FirstLetterOfSurname = '*';

I'm not sure that this is the best solution, any ideas?

Hi there,

IMO, it's cleaner to create an overload that calls the initial method passing in the default value. E.g.:

public static ContactCollection GetContactsByFirstLetterAsCollection(int diaryId)
{
  return GetContactsByFirstLetterAsCollection(diaryId, '*');
}

This way, calling code can skip the firstLetterOfSurname param by simply calling something like:

  GetContactsByFirstLetterAsCollection(5);

while you can still provide a firstLetterOfSurname by calling the other overload:

  GetContactsByFirstLetterAsCollection(5, 's');


Hope this helps,

Imar
