标准化的美国国家arrays和国家arrays

有没有人知道一个很好的，可用的类，这里的每个人都可以从中使用填充国家和州字段的表单上的ComboBox控件？

我讨厌每次都要重新发明轮子，有人可能在某个地方完成了一项非常好的工作。

如果现有类可以在选择国家/地区时返回状态选项列表，则奖励积分！

我目前正在为Windows窗体（非Web应用程序）开发此项目，并且此项目无法从网站上获取。

Answer 1

好的，所以我做了一个。

我构建它很好而且通用，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State Name和State Abbreviation的容器。

 static class StateArray { static List states; static StateArray() { states = new List(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 abbrevList = new List(states.Count); foreach (var state in states) { abbrevList.Add(state.Abbreviations); } return abbrevList.ToArray(); } public static string[] Names() { List nameList = new List(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); } } 

Answer 2

更新了jp2codes示例，并添加了加拿大：

 public static class States { public static List los = new List { //us new State("AL", "Alabama"), new State("AK", "Alaska"), new State("AZ", "Arizona"), new State("AR", "Arkansas"), new State("CA", "California"), new State("CO", "Colorado"), new State("CT", "Connecticut"), new State("DE", "Delaware"), new State("DC", "District Of Columbia"), new State("FL", "Florida"), new State("GA", "Georgia"), new State("HI", "Hawaii"), new State("ID", "Idaho"), new State("IL", "Illinois"), new State("IN", "Indiana"), new State("IA", "Iowa"), new State("KS", "Kansas"), new State("KY", "Kentucky"), new State("LA", "Louisiana"), new State("ME", "Maine"), new State("MD", "Maryland"), new State("MA", "Massachusetts"), new State("MI", "Michigan"), new State("MN", "Minnesota"), new State("MS", "Mississippi"), new State("MO", "Missouri"), new State("MT", "Montana"), new State("NE", "Nebraska"), new State("NV", "Nevada"), new State("NH", "New Hampshire"), new State("NJ", "New Jersey"), new State("NM", "New Mexico"), new State("NY", "New York"), new State("NC", "North Carolina"), new State("ND", "North Dakota"), new State("OH", "Ohio"), new State("OK", "Oklahoma"), new State("OR", "Oregon"), new State("PA", "Pennsylvania"), new State("RI", "Rhode Island"), new State("SC", "South Carolina"), new State("SD", "South Dakota"), new State("TN", "Tennessee"), new State("TX", "Texas"), new State("UT", "Utah"), new State("VT", "Vermont"), new State("VA", "Virginia"), new State("WA", "Washington"), new State("WV", "West Virginia"), new State("WI", "Wisconsin"), new State("WY", "Wyoming"), //canada new State("AB", "Alberta"), new State("BC", "British Columbia"), new State("MB", "Manitoba"), new State("NB", "New Brunswick"), new State("NL", "Newfoundland and Labrador"), new State("NS", "Nova Scotia"), new State("NT", "Northwest Territories"), new State("NU", "Nunavut"), new State("ON", "Ontario"), new State("PE", "Prince Edward Island"), new State("QC", "Quebec"), new State("SK", "Saskatchewan"), new State("YT", "Yukon"), }; public static List Abbreviations() { return los.Select(s => s.Abbreviation).ToList(); } public static List Names() { return los.Select(s => s.Name).ToList(); } public static string GetName(string abbreviation) { return los.Where(s => s.Abbreviation.Equals(abbreviation, StringComparison.CurrentCultureIgnoreCase)).Select(s => s.Name).FirstOrDefault(); } public static string GetAbbreviation(string name) { return los.Where(s => s.Name.Equals(name, StringComparison.CurrentCultureIgnoreCase)).Select(s => s.Abbreviation).FirstOrDefault(); } public static List ToList() { return los; } } public class State { public State(string ab, string name) { Name = name; Abbreviation = ab; } public string Name { get; set; } public string Abbreviation { get; set; } public override string ToString() { return string.Format("{0} - {1}", Abbreviation, Name); } }

我会使用一个小的库包，比如这个： https ： //www.nuget.org/packages/Archon.Enums.Geography/1.0.2

Answer 4

这是适合您的国家版本。

 public class WorldCountry { public WorldCountry() { Name = null; Alpha2Code = null; Alpha3Code = null; NumericCode = null; Enabled = false; } public WorldCountry(string name, string alpha2Code, string alpha3Code, string numericCode, bool enabled) { Name = name;

set; } public string NumericCode { get; set; } public bool Enabled { get; set; } public override string ToString() { //Returns "USA - United States" return string.Format("{0} - {1}", Alpha3Code, Name); } } public class CountryArray { public List countries; public CountryArray() { countries = new List(50); countries.Add(new WorldCountry("Afghanistan", "AF", "AFG", "004", false)); countries.Add(new WorldCountry("Aland Islands", "AX", "ALA", "248", false));

I took jp2code’s answer and just made a tuple with it, rather than creating a new class and all of that… try this:
