标准化美国各州阵列和阵列的国家 [英] Standardized US States Array and Countries Array

问题描述

有谁知道一个好的，可用类的，每个人都在这里可以从为国家和State字段在窗体上填充组合框控件使用？受益

Does anyone know of a nice, usable class that everyone on here could benefit from to use in populating the ComboBox controls on a form for the Country and State fields?

我讨厌不得不每次都推倒重来，有人可能已经做了很不错的作品的地方。

I hate having to reinvent the wheel every time, and someone has probably done a very nice piece of work somewhere.

奖励积分，如果每当选择国家现有的类可以返回的状态选项列表！

Bonus points if the existing class can return a list of State options whenever the Country is selected!

我目前正在开发该Windows窗体（非Web应用程序），而这个项目不能从网站拉。

I'm currently developing this for a Windows Form (non-web application), and this project can't pull from a website.

推荐答案

OK，所以我做了一个。

OK, so I made one.

我建立了它很好的和通用的，所以任何人都应该能够使用它

I built it nice and generic, so anyone should be able to use it

有在所谓的底部 US_States 被用作一个容器来存储国名和国家缩写的一类。

There is a class at the bottom called US_States that is used as a container to store the State Name and State Abbreviation.

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("SC", "South Carolina"));
    states.Add(new US_State("SD", "South Dakota"));

    states.Add(new US_State("TX", "Texas"));
    states.Add(new US_State("UT", "Utah"));

    states.Add(new US_State("VA", "Virginia"));

    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();

      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);
  }

}
