以下代码有什么区别

Question

var id = Convert.ToInt32(GridViewVehicleList.DataKeys[e.NewSelectedIndex].Value);
var id2 = Convert.ToInt32(GridViewVehicleList.DataKeys[e.NewSelectedIndex].Values);

如果我使用第二个代码

id2 = Convert.ToInt32(GridViewVehicleList.DataKeys[e.NewSelectedIndex].Values[1]);

，我可以将第二个DataKey分配给变量id2

感谢所有人的兴趣

Answer 1

DataKey Properties

价值

Gets the value of the key field at index 0 in the DataKey object.

值

object.

所以你可以分配

id2 = Convert.ToInt32(GridViewVehicleList.DataKeys[e.NewSelectedIndex].Values[1]);
