FindCloseMatch

The FindCloseMatch object represents a close match item returned from the Find Search method.

The object is returned as part of the FindResult object. A close match item is a returned match that

closely matches the name of the requested search.

To use this feature, you must first set the UseCloseMatches and CloseMatchesMax properties of the

Find object before you execute your search. For example if you tried to search for “Washington

Street,” and UseCloseMatches was set to true, a close match would be “Washington Ave.”

Code Sample

public void CloseMatchesOnStreetTable()

{

Table _table;

_table = Session.Current.Catalog.OpenTable("Rensselaer.tab");

Find _find = new Find(_table,_table.TableInfo.Columns[1]);

_find.UseCloseMatches = true;

_find.CloseMatchesMax = 5;

FindResult _findResult= _find.Search("70 Washington");

if ((!_findResult.ExactMatch) && (_findResult.NameResultCode ==

FindNameCode.ExactMatchNotFound))

{

FindCloseMatchEnumerator _enum =

_findResult.GetCloseMatchEnumerator();

FindCloseMatch _findCloseMatch;

int _iIndex = 0;

while (_enum.MoveNext())

{

_findCloseMatch = _enum.Current;

Console.WriteLine(_findCloseMatch.Name);

_iIndex++;

}

if(_table != null)

{

_table.Close();

_table = null;

}
