C#中拼音模糊匹配汉字智能搜索

准备：

微软官方出了一个专用的汉字转拼音包Microsoft Visual Studio International Pack 1.0 SR1

首先到官网http://www.microsoft.com/zh-cn/download/details.aspx?id=15251下载安装包，下载完后解压vsintlpack1，里面有7个安装包，只需安装CHSPinYinConv（跟拼音相关）和CHTCHSConv（简体和繁体间的转换）这两个包就可以了，安装完毕后，需要在VS里添加引用。

将C:Program FilesMicrosoft Visual Studio International PackSimplified Chinese Pin-Yin Conversion Library 和C:Program FilesMicrosoft Visual Studio International PackTraditional Chinese to Simplified Chinese Conversion Library and Add-In Tool下的dll  拷贝到项目的dll文件夹下（我的是Reference），接下来添加引用 

Code:

using Microsoft.International.Converters.PinYinConverter;

#region==模糊搜索==
        private void MistinessSel()
        {
            string selwords = GetFormString("words");

            if (selwords != "")
            {
                //判断是汉字还是字母
                string pattern = @"^[A-Za-z]+$";
                Regex regex = new Regex(pattern);
                List<Model.t_category> list = null;
                List<Model.t_category> categorylist = new List<Model.t_category>();
                //字母模糊搜索
                if (regex.IsMatch(selwords))
                {
                    selwords = selwords.ToLower();
                    list = new BLL.t_category().GetModelList(" ParentID!=0 ");

                    //拼音模糊查询法
                    for (int i = 0; i < list.Count; i++)
                    {
                        //StringBuilder str = new StringBuilder();//定义一个可变长度的字符串
                        //char[] chs; //定义一个字符数组来接收每个汉字的拼音
                        string spells = "";
                        //遍历F_ConnName字段中所有汉字
                        foreach (char c in list[i].Name.ToCharArray())
                        {
                            //验证该汉字是否合法
                            if (ChineseChar.IsValidChar(c))
                            {

                                ChineseChar CC = new ChineseChar(c);
                                //将该汉字转化为拼音集合
                                ReadOnlyCollection<string> roc = CC.Pinyins;
                                //获取集合中第一个数据即为该汉字的拼音
                                spells += roc[0].ToLower();
                            }
                        }
                        if (spells.Contains(selwords))
                        {
                            categorylist.Add(list[i]);
                        }
                    }
                }
                else
                {
                    categorylist = new BLL.t_category().GetModelList(" ParentID!=0 and Name  LIKE '%" + selwords + "%'"); ;
                }
                ResponseText(Newtonsoft.Json.JsonConvert.SerializeObject(new { res = 1, list = categorylist }));
            }
            else {
                ResponseText(Newtonsoft.Json.JsonConvert.SerializeObject(new { res = 0 }));
            
            }
        }
