您可以访问所有的按键：

You can access all of the keys:

gridView.DataKeys[rowNum][dataKeyName]

其中的rowNum是e.RowIndex从gridView_RowDeleting事件处理程序，dataKeyName就是要拿到钥匙：

where rowNum is e.RowIndex from the gridView_RowDeleting event handler, and dataKeyName is the key you want to get:

<asp:GridView ID="gridView" runat="server" DataKeyNames="userid, id1, id2, id3" OnRowDeleting="gridView_RowDeleting">

protected void gridView_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    gridView.DataKeys[e.RowIndex]["userid"]...
    gridView.DataKeys[e.RowIndex]["id1"]...
    gridView.DataKeys[e.RowIndex]["id2"]...
    gridView.DataKeys[e.RowIndex]["id3"]...
}
