C#如何实现统计数组个数

[qq_35631598]

static void text1(string x)
{
char[] any = { ' ', ',', '.', ';', '?', '!' };
int istart = 0;
int iend = 0;
string[] value= new string[100];
do{
iend = x.IndexOfAny(any,istart);
if (iend == -1) iend = x.Length;
if (iend != istart)
{
int i=1;
value[i] = x.Substring(istart, (iend - istart));
i++;
}
istart = iend + 1;
}while(istart<x.Length);
??????????????????????????????????????????
}

目的在于统计单词出现频率

统计某个单词在字符串中的个数？

        /// <summary>
        /// 统计某个单词在字符串中的个数
        /// </summary>
        /// <param name="keyword">关键字</param>
        /// <param name="strs">整个文本</param>
        /// <returns>重复个数</returns>
        private int DuplicateWordCount(string keyword, string strs)
        {
            int dupCount = 0;
            char[] any = { ' ', ',', '.', ';', '?', '!' };
            string[] words = strs.Split(any, StringSplitOptions.RemoveEmptyEntries);
            for (int i = 0; i < words.Length; i++)
            {
                if (words[i].ToString().ToUpper() == keyword.ToUpper()) //不区分大小写
                    dupCount++;
            }
            return dupCount;
        }

就是单词统计是吧 为何要用这种c的语法来写呢

static void text1(string text)
        {
            char[] any = { ' ', ',', '.', ';', '?', '!' };
            var list = text.Split(any).GroupBy(x => x);
            foreach (var group in list)
            {
                Console.WriteLine("{0}={1}", group.Key, group.Count());
            }
        }

同2楼，如果只是统计单词出现次数，那就groupby分组一下
