我正在以字典的形式使用一种字符串数组集合,因为......

Dictionary&lt;(key:topic),(value:string array#File.ReadAllLines(#somepath))&gt;

示例:

        public static Dictionary<string, string[]> flags = new Dictionary<string, string[]>()
        {
            { "food", new string[] { l_food }};
        }


        public static string[] l_food = File.ReadAllLine(_path + @"..//..//lists/food.txt");

我的目标是使用我的班级:

    public class Algorithms
    {
        public static string Main(string message)
        {
            return Get_Response(Get_Topic(message));
        }

        private string Get_Topic(string message)
        {
            string[] words = message.Split(' ');
            foreach (string word in words)
            {
                foreach (KeyValuePair<string, string[]> flag in Responses.flags)
                {
                    if (Responses.ignore.Contains(word) == true) ;
                    else if (flag.Value.ContainsValue(word) == true && Responses.ignore.Contains(word) == false) return flag.Key;
                    else if (flag.Value.ContainsValue(word) == false && word == " " || word == null) return "afk";
                    else return "general";
                }
            }
            return null;
        }

        private string Get_Response(string topic)
        {
            switch (topic)
            {
                case "music":
                    return Set_Response(Responses.r_music);
                case "art":
                    return Set_Response(Responses.r_art);
                case "mathmatics":
                    return Set_Response(Responses.r_mathmatics);
                case "military":
                    return Set_Response(Responses.r_military);
                case "technology":
                    return Set_Response(Responses.r_technology);
                case "science":
                    return Set_Response(Responses.r_science);
                case "religion":
                    return Set_Response(Responses.r_religion);
                case "sex":
                    return Set_Response(Responses.r_sex);
                case "wealth":
                    return Set_Response(Responses.r_wealth);
                case "job":
                    return Set_Response(Reponses.r_job);
                case "games":
                    return Set_Response(Responses.r_games);
                case "food":
                    return Set_Response(Responses.r_food);
                case "politics":
                    return Set_Response(Responses.r_politics);
                case "movie":
                    return Set_Response(Responses.r_movie);
                case "general":
                    return Set_Response(Responses.r_general);
                case "afk":
                    return Set_Response(Responses.r_afk);
                }
            }

            public string Set_Response(string[] topic)
            {
                return topic[(int)new Random().Next(topic.Length)];
            }
        }

...通过匹配我的忽略列表中没有从字符串数组中删除的可能单词(从文本文件加载)来从用户的消息中获取“主题”(即食物)。

这是我正在搞乱的聊天机器人应用程序,但是当我看到这个问题时会出现问题

错误CS0029:无法隐式转换类型string[]' to字符串'(CS0029)(SimpleMan)

请注意,这个IDE是MonoDevelop,因为我的笔记本电脑是一个糟糕的2003 linux盒子......

我真的不知道......

答案 0 :(得分:0)

试试这个:

public static Dictionary<string, string[]> flags = new Dictionary<string, string[]>()
{
    { "food",  l_food };
}

l_food已经是string[]
