Question

我循环遍历一个数组，我再次循环这些值以使其与字符串匹配，如果整个给定的字符串匹配将是数组的整个元素，我应该打印该字符串，但它不起作用

public class find
{
string[] inputs = {"Third Street Promenade, 1220 3rd St ,Santa Monica, CA 90401","Hi there should"};
string store_tran1 = "1220 3rd St ,Santa Monica, CA 90401"

foreach(var store in stores){

                        List<string> outputs = new List<string>();
foreach (var input in inputs)
                        {
                            outputs.AddRange((new String(input.ToCharArray()
                                .Where(c => Char.IsLetterOrDigit(c) || c == ' ')
                                .ToArray()).Split(' ')));
                        }
foreach (var output in outputs)
                            {



                                //string sto = store.ToString ();
                                //Console.Write (output+"\n");
                                bool store_match_check_1 = Regex.IsMatch (store_tran1, @""+Regex.Escape (output)+"", RegexOptions.IgnoreCase);
                                if (store_match_check_1 == true) {
                                    //string store_match_check1 = store_match_check_1.Groups [1].Value;

                                     res = true;

                                } else {
                                    store_array_check.Add ("one");
                                    res = false;
                                }


                            }


} 
}

预期产出：

Third Street Promenade, 1220 3rd St ,Santa Monica, CA 9040

我怎么能得到这个woking

Answer 1

为什么不

var inputs = new[] { "Third Street Promenade, 1220 3rd St ,Santa Monica, CA 90401", "Hi there should" };
var store_tran1 = "1220 3rd St ,Santa Monica, CA 90401";
foreach (var input in inputs)
{
    if (input.Contains(store_tran1))
    {
        Console.WriteLine(input);
    }
}

（如果您需要，可以通过调用ToLower()或调用Trim()来删除空格来忽略大小写）

你的正则表达式是从输入字符串中删除逗号，因此你不会得到任何匹配。

如果你真的想要删除所有非字母数字字符+逗号，你可以像这样使用LINQ：

var inputs = new[] {"Third Street Promenade, 1220 3rd St ,Santa Monica, CA 90401","Hi there should"};
var store_tran1 = "1220 3rd St ,Santa Monica, CA 90401";
inputs.Select(s => Regex.Replace(s, @"^\s*|[^\w\s,]+|\s*$", ""))
      .Where(s => s.Contains(store_tran1))
      .ToList()
      .ForEach(Console.WriteLine);

正则表达式还将从输入字符串的开头和结尾修剪空格。
