ASP.NET实现按拼音码模糊查询的方法

protected void Button1_Click1(object sender, EventArgs e) { string strSQL; strSQL = "select mc from TEST001"; IDataReader dr = dac.DataReaderQuery(strSQL); while (dr.Read()) {  string mc=dr["mc"].ToString();  string pym = StrToPinyin.GetChineseSpell(mc);  if (pym.Length > 6)  {  pym = pym.Substring(0, 6);//我这里只去了6位，大家可以看自己爱好而定！  }   string updateSql = "update TEST001 set pym ='" + pym + "' where mc='" + mc + "'";  dac.update(updateSql); } dr.Close();  Response.Write("<script>alert('操作成功!');</script>"); }StrToPinyin 类的GetChineseSpell方法（取汉字拼音字母）：public static string GetChineseSpell(string strText) { if (strText == null || strText.Length == 0)  return strText; System.Text.StringBuilder myStr = new System.Text.StringBuilder(); foreach (char vChar in strText) {  // 若不是汉字则直接输出   if ((int)vChar < 19968 || (int)vChar > 40869)  {  myStr.Append(char.ToUpper(vChar));  }  else if ((int)vChar >= 19968 && (int)vChar <= 40869)  {  // 若字符Unicode编码在编码范围则 查汉字列表进行转换输出   foreach (string strList in strChineseCharList)  {   if (strList.IndexOf(vChar) > 0)   {   myStr.Append(strList[0]);   break;   }  }  } } return myStr.ToString(); }
