範例

以下範例建立一個 DataColumnMapping 物件並將其加入 DataColumnMappingCollection 集合。 接著它會告訴使用者該映射已被加入集合，並顯示映射的父版本。


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
