C#如何实现字数统计？

[dvdvip]

在Form1里面，有一个TextBox1, 设置为多行。点击按钮后，就弹出对话框，显示字数统计。就是像Word一样的，不是显示字符数。而是显示有多少个英文单词。而且，要忽略空格，回车换行符，和标点符号。用C#如何实现？

private void Button1_Click(object sender,EventArgs e)
{MessaageBox.Show("The word count of your article is: ")+TextBox1的单词数;}

用正则。

稍微改了下小BUG

 private void button1_Click(object sender, EventArgs e)
        {
            string test = textBox1.Text.Replace(". ", ".").Replace(", ", ",").TrimEnd('.');             int i = CountWords(test);
            MessageBox.Show(i.ToString());
        }

        public int CountWords(string input)
        {
            int len = 0;

            string s = input.Replace("\r", " ").Replace("\n", " "); //去除回车和换行
            Regex regex = new Regex(@"\s+");
            s = regex.Replace(s, " ");
            //空格 
            string[] sAl = s.Split(' ');

            for (int i = 0; i < sAl.Length; i++)
            {
                //逗号 
                string[] sDh = sAl[i].Split(',');

                for (int j = 0; j < sDh.Length; j++)
                {
                    //句号 
                    string[] sJh = sDh[j].Split('.');

                    for (int k = 0; k < sJh.Length; k++)
                    {
                        if (sJh[k] != " ")
                            len++;
                    }
                }
            }
            return len;
        }

笼统来说，正则，但是有点小困难，如果你的文字仅英文，每个单词都空格，直接用string [] mStrSplit = YourTextString.Split(' '),然后取mStrSplit.Length-1即可

MessaageBox.Show
(
  "The word count of your article is: " +
  System.Text.RegularExpressions.Regex.Matches(s, @"\w+").Count
);
