 DataTableMapping();

public DataTableMapping ();

Public Sub New ()

Contoh

Contoh berikut membuat DataTableMapping objek.

{
    DataTableMapping mapping = new DataTableMapping();
    mapping.SourceTable = "Categories";
    mapping.DataSetTable = "DataCategories";
}

Public Sub CreateDataTableMapping()
    Dim mapping As New DataTableMapping()

public:
 DataTableMapping(System::String ^ sourceTable, System::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)

DataTableMapping(String, String, DataColumnMapping[])

Sumber:

DataTableMapping.cs

Menginisialisasi instans DataTableMapping baru kelas saat diberi nama tabel sumber, DataTable nama, dan array DataColumnMapping objek.

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())

Parameter

sourceTable

String

Nama tabel sumber peka huruf besar/kecil dari sumber data.

dataSetTable

String

Nama tabel dari ke DataSet peta ke.

columnMappings

DataColumnMapping[]

Array DataColumnMapping objek.

Contoh

Contoh berikut membuat DataTableMapping objek, mengatur beberapa propertinya, dan menyalinnya ColumnMappings ke array. Contoh ini mengasumsikan bahwa telah DataColumnMappingCollection dibuat.

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
