C# 获取字符串数组中包含某个字符的元素的个数

比如string[] a={a b c ,a a c ,a c c ,a e c};

如何获取字符串数组a中 包含b字符的元素个数

Answer 1

 static void Main(string[] args){

         string[] a={"abc","aac","acc","aec"};
         int count = 0;
         foreach (var item in a)
         {
             if(item.Contains("b")) count++;
         }
         Console.WriteLine(count);
        }

Answer 2

        //using System.Linq;
        static void Main(string[] args)
        {
            string[] a = { "ab", "ac", "b", "ac", "bc", "c" };
            int bcnt = a.Count(x => x.Contains("b"));
            Console.WriteLine(bcnt);//3
            Console.ReadLine();
        }

Answer 3

private int Function(string[] strArr, char b)
{
   return (from q in strArr
               where q.Contains(b)
               select q).Count();
}

Answer 4

 int count = 0;
            for (int i = 0; i < a.Length; i++)
                if (a[i].Contains("b"))
                    count++;

Answer 5

int nResult = a.Where(c => c == "b").ToArray().Length;
nResult就是
