範例

下列範例會 DataColumnMapping 建立 物件，並將其新增至 DataColumnMappingCollection 集合。 然後，它會告知用戶對應已新增至集合，並顯示對應的父代。

public void AddDataColumnMapping() {
   // ...
   // create columnMappings
   // ...
   DataColumnMapping mapping =
      new DataColumnMapping("Description","DataDescription");
   columnMappings.Add((Object) mapping);
   Console.WriteLine("Column {0} added to column mapping collection {1}.",
       mapping.ToString(), columnMappings.ToString());
}

Public Sub AddDataColumnMapping()
    ' ...
    ' create columnMappings
    ' ...
    Dim mapping As New DataColumnMapping( _
       "Description", "DataDescription")
    columnMappings.Add(CType(mapping, Object))
    Console.WriteLine("Column {0} added to column mapping collection {1}.", _
       mapping.ToString(), columnMappings.ToString())
End Sub
