请教这是泛型吗?怎样操作查询和删除啊?谢谢
List<Customer> customers = new List<Customer> {new Customer { ID="A", City="New York", Country="USA", Region="North America", Sales=9999},
new Customer { ID="B", City="Mumbai", Country="India", Region="Asia", Sales=8888},
new Customer { ID="T", City="Lima", Country="Peru", Region="South America", Sales=2002 }
};
//想对City="Mumbai",进行操作
textBox1.Text = customers.IndexOf(这里写什么?).ToString());
customers.Remove(这里写什么?);
本人是刚学习c#,请教这是泛型变量吗?如果查询其位置、删去其中符合条件的一组数据?
