如何在数组中查找 包含的内容举例string[] str = { "art", "bti", "cip","lifr","ui","pu","eu","cgh","sloq", }; 查找 u 要最快的方法谢谢

Question

举例string[] str = { "art", "bti", "cip","lifr","ui","pu","eu","cgh","sloq", };

数组中查找 a="u"; 的值 如果找到 就返回 含 U 的所有  数值 为 ui  pu   如果没找到 返回 "未找到"

 

Answer 1

string[] FindMatchList(string[] list, string str)
        {
            var matchList = list.ToList().Where(x => x.IndexOf(str) >= 0).ToArray();
            if (matchList == null || matchList.Length == 0) throw new Exception("未找到");
            return matchList;
        }

是不是最快的不清楚，不过基本就这样了

因为和C#开发相关，我帮你移到更合适的语言开发论坛。

Answer 3

string[] str = { "art", "bti", "cip", "lifr", "ui", "pu", "eu", "cgh", "sloq", };
            var list = str.Where(m => m.Contains("u")).ToList();
            //遍历
            foreach(var p in list)
            {
                Response.Write(string.Format("{0}<br>", p));
            }
            //返回字符串
            Response.Write(string.Join(",", list));

Answer 4

Hi ning050089,

我测试 上面这个代码

var list = str.Where(m => m.Contains("u")).ToList();

是完全可以实现你的要求，而且判断循环已是最少，应该是比较快的。
