Question

我有代码声明：

 public IDictionary<string, OPTIONS> dict_Options = new Dictionary<string, OPTIONS>();

 public class OPTIONS
 {
        public string subjectId = string.Empty;
        public string varNumber = string.Empty;
        public string varName = string.Empty;
 }

迭代我的字典对象中的所有varNames的最简单方法是什么？有没有像foreach一样？

Answer 1

        foreach (var item in dict_Options)
        {
            string varName = item.Value.varName;
        }

这会遍历词典中的所有KeyValuePair<T, T>

Answer 2

只需添加已发布的优秀答案的替代方案，您就可以：

dict_Options.Keys.ToList().ForEach(m => SomeFunc(m.Value.varName));

Answer 3

foreach(var name in dict_Options.Select(x => x.Value.varName))
{
    SomeFunc(name);
}

迭代IDictionary / Dictionary对象
