c# – 标准化的美国阵列和国家阵列

有人知道一个好的可用的类,这里的每个人都可以从在国家和州领域的表单上填充Combo@R_490_2419@控件中获益吗?

我讨厌不得不每次重塑轮子,有人可能在某处做了很好的工作.

奖励积分,如果现有的班级可以在选择国家时返回州选项列表!

我正在为Windows窗体(非Web应用程序)开发此项目,该项目不能从网站拉出.

解决方法 好的,所以我做了一个.

我建立它很好,通用,所以任何人都应该能够使用它

底部有一个名为US_States的类,用作存储状态名和状态缩写的容器.

static class StateArray { static List<US_State> states; static StateArray() { states = new List<US_State>(50); states.Add(new US_State(“AL”,”Alabama”)); states.Add(new US_State(“AK”,”Alaska”)); states.Add(new US_State(“AZ”,”Arizona”)); states.Add(new US_State(“AR”,”Arkansas”)); states.Add(new US_State(“CA”,”California”)); states.Add(new US_State(“CO”,”Colorado”)); states.Add(new US_State(“CT”,”Connecticut”)); states.Add(new US_State(“DE”,”Delaware”)); states.Add(new US_State(“DC”,”District Of Columbia”)); states.Add(new US_State(“FL”,”Florida”)); states.Add(new US_State(“GA”,”Georgia”)); states.Add(new US_State(“HI”,”Hawaii”)); states.Add(new US_State(“ID”,”Idaho”)); states.Add(new US_State(“IL”,”Illinois”)); states.Add(new US_State(“IN”,”Indiana”)); states.Add(new US_State(“IA”,”Iowa”)); states.Add(new US_State(“KS”,”Kansas”)); states.Add(new US_State(“KY”,”Kentucky”)); states.Add(new US_State(“LA”,”Louisiana”)); states.Add(new US_State(“ME”,”Maine”)); states.Add(new US_State(“MD”,”Maryland”)); states.Add(new US_State(“MA”,”Massachusetts”)); states.Add(new US_State(“MI”,”Michigan”)); states.Add(new US_State(“MN”,”Minnesota”)); states.Add(new US_State(“MS”,”Mississippi”)); states.Add(new US_State(“MO”,”Missouri”)); states.Add(new US_State(“MT”,”Montana”)); states.Add(new US_State(“NE”,”Nebraska”)); states.Add(new US_State(“NV”,”Nevada”)); states.Add(new US_State(“NH”,”New Hampshire”)); states.Add(new US_State(“NJ”,”New Jersey”)); states.Add(new US_State(“NM”,”New Mexico”)); states.Add(new US_State(“NY”,”New York”)); states.Add(new US_State(“NC”,”North Carolina”)); states.Add(new US_State(“ND”,”North Dakota”)); states.Add(new US_State(“OH”,”Ohio”)); states.Add(new US_State(“OK”,”Oklahoma”)); states.Add(new US_State(“OR”,”Oregon”)); states.Add(new US_State(“PA”,”Pennsylvania”)); states.Add(new US_State(“RI”,”Rhode Island”)); states.Add(new US_State(“SC”,”South Carolina”)); states.Add(new US_State(“SD”,”South Dakota”)); states.Add(new US_State(“TN”,”Tennessee”)); states.Add(new US_State(“TX”,”Texas”)); states.Add(new US_State(“UT”,”Utah”)); states.Add(new US_State(“VT”,”Vermont”)); states.Add(new US_State(“VA”,”Virginia”)); states.Add(new US_State(“WA”,”Washington”)); states.Add(new US_State(“WV”,”West Virginia”)); states.Add(new US_State(“WI”,”Wisconsin”)); states.Add(new US_State(“WY”,”Wyoming”)); } public static string[] Abbreviations() { List<string> abbrevList = new List<string>(states.Count); foreach (var state in states) { abbrevList.Add(state.Abbreviations); } return abbrevList.ToArray(); } public static string[] Names() { List<string> nameList = new List<string>(states.Count); foreach (var state in states) { nameList.Add(state.Name); } return nameList.ToArray(); } public static US_State[] States() { return states.ToArray(); }}class US_State { public US_State() { Name = null; Abbreviations = null; } public US_State(string ab,string name) { Name = name; Abbreviations = ab; } public string Name { get; set; } public string Abbreviations { get; set; } public override string ToString() { return string.Format(“{0} – {1}”,Abbreviations,Name); }}
