以下範例建立一個 DataTableMapping 物件，設定部分屬性，並將其複製 ColumnMappings 到陣列。 此例假設已創造 a DataColumnMappingCollection 。

public void CreateDataTableMapping()
{
    // ...
    // create mappings
    // ...
    DataColumnMapping[] columns = {};
    // Copy mappings to array
    mappings.CopyTo(columns, 0);
    DataTableMapping mapping =
        new DataTableMapping("Categories", "DataCategories", columns);
}

Public Sub CreateDataTableMapping()
    ' ...
    ' create mappings
    ' ...
    Dim columns() As DataColumnMapping
    ' Copy mappings to array
    mappings.CopyTo(columns, 0)
    Dim mapping As New DataTableMapping _
       ("Categories", "DataCategories", columns)
End Sub
