替换成你好刘翔，我是china，你去哪
。最好有代码。。谢谢啊

Answer 1

  //定义规则
            Dictionary<string, string> rules = new Dictionary<string, string>() {
                {"&","刘翔"},
                {"@","chnai"},
                {"*","哪"}
            };
            string str="你好&，我是@，你去*";
            foreach (var item in rules)
            {             
                str = str.Replace(item.Key,item.Value);
            }
            //你好刘翔，我是chnai，你去哪"

Answer 2

那就往字典中循环加入变量，上面只不过是初始化后赋了初始值而已
rules.Add(TKey,TValue); 

Answer 3

用正则更方便
            string str = "你好&，我是@，你去*";
            Dictionary<string, string> dict = new Dictionary<string, string> {
                {"&","刘翔"},
                {"@","china"},
                {"*","哪"}
            };            MatchEvaluator func = (m) =>
                {
                    string value;                    if (dict.TryGetValue(m.Groups[0].Value, out value))
                        return value;
                    else
                        return m.Value;
                };
            str = Regex.Replace(str, @"[&@\*]", func);
            Console.WriteLine(str);
