The GetDistinctFieldValues method of the SPList class returns a two-dimensional object array of field values in which data duplication within a specified field in the list is eliminated and each value returned is unique.

Parameters

field   A Microsoft.SharePoint.SPField object that represents the field.

columnItems   A two-dimensional object array that is passed as an out parameter and that returns the values.
