C#中文分词算法：IKAnalyzerNet的使用。

需要先引用dll库文件 IKAnalyzerNet.dll + Lucene.Net.dll + PowerCollections.dll 这三个，打包在本文下方，使用VS2008调试通过：

using IKAnalyzerNet;
using IKAnalyzerNet.dict;
using Lucene.Net.Analysis;
using Wintellect.PowerCollections;

使用方法举例：

        private void button1_Click(object sender, EventArgs e)
        {
            String testString = richTextBox2.Text ;
            String slen = testString.Length.ToString();

IKAnalyzer ika = new IKAnalyzer();

            System.IO.TextReader r = new System.IO.StringReader(testString);
            TokenStream ts = ika.TokenStream("TestField", r);
            int m = 0;
            long begin = System.DateTime.Now.Ticks;
            for (Token t = ts.Next(); t != null; t = ts.Next())
            {
                m++;
                richTextBox1.Text += m + ")" + (t.StartOffset() + "," + t.EndOffset() + " = " + t.TermText()) + "\r\n";
            }

int end = (int)((System.DateTime.Now.Ticks - begin) / 10000);

richTextBox1.Text += ("长度：" + slen + " 耗时： " + (end) + "ms" + " 分词个数：" + m + " 效率(词/秒)：" + ((int)(m * 1.0f / (end) * 1000))) + "\r\n";
}

截图如下：
