c# - 数组的静态类成员

Question

如何获取一个包含类的所有静态字符串的数组？

我有什么:

public static class A
{
    public static class BA
    {
        public const string BAA = "baa";
        public const string BAB = "bab";
        public const string BAC = "bac";
    }
    public static class BB
    {
        public const string BBA = "bba";
        public const string BBB = "bbb";
        public const string BBC = "bbc";
    }
}

我想要的:

string[] BAs = new string[]{"baa","bab","bac"};
string[] BBs = new string[]{"bba","bbb","bbc"};

也很好(但更喜欢上面的解决方案):

string[] BAs = new string[]{"BAA","BAB","BAC"};
string[] BBs = new string[]{"BBA","BBB","BBC"};

一些伪代码:

string[] BAs = A.BA.GetAllStringVariablesFromStaticMembers();
string[] BBs = A.BB.GetAllStringVariablesFromStaticMembers();

这可能吗？如果是，我该怎么做？

附加信息:静态类内部只包含静态字符串，因此通用成员方法也是可能的，但我更喜欢该方法只返回给定类的静态字符串。

您可以通过反射使用稍微不同的语法来做到这一点:

public static String[] GetAllStringVariablesFromStaticMembers(Type value) {
  if (Object.ReferenceEquals(null, value))
    throw new ArgumentNullException("value");

  List<String> result = new List<String>();

  foreach (FieldInfo fi in value.GetFields(BindingFlags.Static | BindingFlags.Public)) 
    if (fi.FieldType == typeof(String))
      result.Add(fi.GetValue(null) as String);

  return result.ToArray();
}

...

string[] BAs = GetAllStringVariablesFromStaticMembers(typeof(A.BA));
