C#中拼音模糊匹配漢字智能搜索

准備：

微軟官方出了一個專用的漢字轉拼音包Microsoft Visual Studio International Pack 1.0 SR1

首先到官網http://www.microsoft.com/zh-cn/download/details.aspx?id=15251下載安裝包，下載完后解壓vsintlpack1，里面有7個安裝包，只需安裝CHSPinYinConv（跟拼音相關）和CHTCHSConv（簡體和繁體間的轉換）這兩個包就可以了，安裝完畢后，需要在VS里添加引用。

將C:\Program Files\Microsoft Visual Studio International Pack\Simplified Chinese Pin-Yin Conversion Library 和C:\Program Files\Microsoft Visual Studio International Pack\Traditional Chinese to Simplified Chinese Conversion Library and Add-In Tool下的dll  拷貝到項目的dll文件夾下（我的是Reference），接下來添加引用 

Code:

using Microsoft.International.Converters.PinYinConverter;

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

            if (selwords != "")
            {
                //判斷是漢字還是字母
                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 ");

                    //拼音模糊查詢法
                    for (int i = 0; i < list.Count; i++)
                    {
                        //StringBuilder str = new StringBuilder();//定義一個可變長度的字符串
                        //char[] chs; //定義一個字符數組來接收每個漢字的拼音
                        string spells = "";
                        //遍歷F_ConnName字段中所有漢字
                        foreach (char c in list[i].Name.ToCharArray())
                        {
                            //驗證該漢字是否合法
                            if (ChineseChar.IsValidChar(c))
                            {

                                ChineseChar CC = new ChineseChar(c);
                                //將該漢字轉化為拼音集合
                                ReadOnlyCollection<string> roc = CC.Pinyins;
                                //獲取集合中第一個數據即為該漢字的拼音
                                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 }));
            
            }
        }
