关于读取webconfig并绑定到dropdownlist上的问题

Question

ConfigurationSettings.AppSettings["State0"]
ConfigurationSettings.AppSettings["State1]

Answer 1

string str = ConfigurationManager.AppSettings.["State0"];
DropDownList1.Items.Add(new ListItem(str, str[0].ToString()));str = ConfigurationManager.AppSettings.["State1"];
DropDownList1.Items.Add(new ListItem(str, str[0].ToString()));

Answer 2

错了，应该是 ConfigurationManager.AppSettings["State0"]

Answer 3

那我每次修改一次webconfig都要去加一个add 那就没有什么意义了！
