C#中文分词算法：ChineseAnalyzer

1.首先需要引用 2个dll库文件 Lucene.Net.dll + Lucene.China.dll

using Lucene.Net;
using Lucene.Net.Analysis;
using Lucene.China;

2.还有一个data文件夹需要放在C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0目录下

里面有三个文件

（1）.sDict.txt

（2）.sDict.txt.bak

（3）.sNoise.txt

这三个文件主要是用来根据那些词去分词的词语如图：

代码实例：

protected void Button1_Click(object sender, EventArgs e)
    {
        StringBuilder sb = new StringBuilder();
        sb.Remove(0, sb.Length);
        string t1 = "";
        int i = 0;
        Analyzer analyzer = new Lucene.China.ChineseAnalyzer();
        StringReader sr = new StringReader(TextBox1.Text);
        TokenStream stream = analyzer.TokenStream(null, sr);

        long begin = System.DateTime.Now.Ticks;
        Token t = stream.Next();
        while (t != null)
        {
            t1 = t.ToString();   //显示格式： (关键词,0,2) ，需要处理
            t1 = t1.Replace("(", "");
            char[] separator = { ',' };
            t1 = t1.Split(separator)[0];

            sb.Append(i + ":" + t1 + "\r\n");
            t = stream.Next();
            i++;
        }
        TextBox2.Text = sb.ToString();
        long end = System.DateTime.Now.Ticks; //100毫微秒
        int time = (int)((end - begin) / 10000); //ms

TextBox2.Text += "耗时" + (time) + "ms \r\n=====\r\n";
}

运行结果如图：
