给定源表名称和 DataTable 名称时,使用源初始化 DataTableMapping 类的新实例。
public:
DataTableMapping(System::String ^ sourceTable, System::String ^ dataSetTable);
public DataTableMapping (string? sourceTable, string? dataSetTable);
public DataTableMapping (string sourceTable, string dataSetTable);
new System.Data.Common.DataTableMapping : string * string -> System.Data.Common.DataTableMapping
Public Sub New (sourceTable As String, dataSetTable As String)
参数
- sourceTable
- String

{
DataTableMapping mapping =
new DataTableMapping("Categories","DataCategories");
}
Public Sub CreateDataTableMapping()
Dim mapping As New DataTableMapping("Categories", "DataCategories")

给定源表名称、DataTable 名称和 DataColumnMapping 对象数组时,初始化 DataTableMapping 类的新实例。
public:
DataTableMapping(System::String ^ sourceTable, System::String ^ dataSetTable, cli::array <System::Data::Common::DataColumnMapping ^> ^ columnMappings);
public DataTableMapping (string? sourceTable, string? dataSetTable, System.Data.Common.DataColumnMapping[]? columnMappings);

new System.Data.Common.DataTableMapping : string * string * System.Data.Common.DataColumnMapping[] -> System.Data.Common.DataTableMapping
Public Sub New (sourceTable As String, dataSetTable As String, columnMappings As DataColumnMapping())
参数
- sourceTable
- String
数据源中区分大小写的源表名称。
- columnMappings
- DataColumnMapping[]
一个 DataColumnMapping 对象数组。
示例
以下示例创建 一个 DataTableMapping 对象,设置其一些属性,并将其复制到 ColumnMappings 数组。 此示例假定 DataColumnMappingCollection 已创建 。
public void CreateDataTableMapping()
{
// ...
// create mappings
// ...
DataColumnMapping[] columns1 = {};
mappings.CopyTo(columns1, 0);
DataTableMapping mapping =
new DataTableMapping("Categories", "DataCategories", columns1);
DataColumnMapping[] columns2 = {};
mapping.ColumnMappings.CopyTo(columns2, 0);
}
Public Sub CreateDataTableMapping()
' ...
' create mappings
' ...
Dim columns1() As DataColumnMapping
mappings.CopyTo(columns1, 0)
Dim mapping As New DataTableMapping _
("Categories", "DataCategories", columns1)
Dim columns2() As DataColumnMapping
mapping.ColumnMappings.CopyTo(columns2, 0)
End Sub
