C# 2008 SP1.
C# 2008 SP1。
I am deleting a row from a row that is currently selected on a datagridview.
我正在从当前在 datagridview 上选择的行中删除一行。
I am using a Typed dataset and my datagridview is bounded to a binding source.
我正在使用类型化数据集，并且我的 datagridview 绑定到绑定源。
However, I think my technique is not the best, even though it works.
然而，我认为我的技术不是最好的，即使它有效。
Many thanks for any advice,
非常感谢您的任何建议，
DataRow[] drDelete;
// Get the value of the PK from the currently selected row
DataRowView drv = (DataRowView)bsAddressBook.Current;
int index = Convert.ToInt16(drv[0]);
// Find the actual data row from the primary key and delete the row
drDelete = dsCATDialer.AddressBook.Select(string.Format("ID = '{0}'", index));
dsCATDialer.AddressBook.Rows.Remove(drDelete[0]);

I think you can shorten this using the Row property of the DataRowView.
我认为您可以使用 DataRowView 的 Row 属性来缩短它。
// Get the value of the PK from the currently selected row
DataRowView drv = (DataRowView)bsAddressBook.Current;
DataRow drDelete = drv.Row;
dsCATDialer.AddressBook.Rows.Remove(drDelete);

You could also delete directly using the BindingSource :
您也可以使用 BindingSource 直接删除：
bsAddressBook.RemoveCurrent();
