public:
 property long AutoIncrementStep { long get(); void set(long value); };
public long AutoIncrementStep { get; set; }
[System.Data.DataSysDescription("DataColumnAutoIncrementStepDescr")]
public long AutoIncrementStep { get; set; }
member this.AutoIncrementStep : int64 with get, set
[<System.Data.DataSysDescription("DataColumnAutoIncrementStepDescr")>]
member this.AutoIncrementStep : int64 with get, set
Public Property AutoIncrementStep As Long

範例

下列範例會設定 AutoIncrementAutoIncrementSeedAutoIncrementStep 屬性。

private void AddAutoIncrementColumn()
{
    DataColumn column = new DataColumn();
    column.DataType = System.Type.GetType("System.Int32");
    column.AutoIncrement = true;
    column.AutoIncrementSeed = 1000;
    column.AutoIncrementStep = 10;

    // Add the column to a new DataTable.
    DataTable table = new DataTable("table");
    table.Columns.Add(column);
}
Private Sub AddAutoIncrementColumn()
    Dim column As New DataColumn()
    column.DataType = System.Type.GetType("System.Int32")
    With column
        .AutoIncrement = True
        .AutoIncrementSeed = 1000
        .AutoIncrementStep = 10
    End With

    ' Add the column to a new DataTable.
    Dim table As DataTable
    table = New DataTable
    table.Columns.Add(column)
End Sub
