示例

下面的示例将 AllowNew 属性设置为 true,然后使用 AddNew 方法添加新行。The following example sets the AllowNew property to true before adding a new row with the AddNew method.

private void AddNew()
{
    DataTable table = new DataTable();

    // Not shown: code to populate DataTable.

    DataView view = new DataView(table);
    view.AllowNew = true;
    DataRowView rowView = view.AddNew();
    rowView["ProductName"] = "New Product Name";
}
Private Sub AddNew()
    Dim table As New DataTable()

    ' Not shown: code to populate DataTable.

    Dim view As New DataView(table)
    view.AllowNew = True
    Dim rowView As DataRowView
    rowView = view.AddNew
    rowView("ProductName") = "New Product Name"
End Sub
