c# - 标准化的美国州数组和国家数组

Question

有谁知道一个很好用的类，这里的每个人都可以使用它来填充表单上的 ComboBox 控件以用于 Country 和 State 字段？

我讨厌每次都必须重新发明轮子，而某人可能在某个地方做了非常好的工作。

如果在选择国家/地区时现有类可以返回州选项列表，则可加分!

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中提取。

Answer 1

好的，所以我做了一个。

我把它做得很好而且很通用，所以任何人都应该能够使用它

底层有一个名为US_States的类，用作存储州名和州缩写的容器。

static class StateArray {

  static List<US_State> states;

  static StateArray() {
    states = new List<US_State>(50);
    states.Add(new US_State("AL", "Alabama"));

  }

  public static string[] Abbreviations() {

    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);
  }
