如何按汉字的拼音排序建筑物名称呢？这个问题是我在项目的实际开发中遇到的，下面是我解决的办法：

在网上搜索了下

（1）获取建筑物名称的每个汉字的拼音首个字母，代码如下：


using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

/* 
* 说明:此类用于将一个字符串找出首字声母,用法:ChineseConvert.UtilIndexCode(str); 
* 
* 
*/ 

namespace InforEnergy.Class
{
public class ChineseConvertToLetter
    {
public ChineseConvertToLetter()
        {

        }
/// <summary> 
/// 返回字符串的首写字母字符串 
/// </summary> 
/// <param name="IndexTxt">需得到首写字母的字符串</param> 
/// <returns></returns> 
        public static String UtilIndexCode(String IndexTxt)
        {
string _Temp = null;
for (int i = 0; i < IndexTxt.Length; i++)
                _Temp = _Temp + GetOneIndex(IndexTxt.Substring(i, 1));
return _Temp;
        }

//得到单个字符的首字母 
        private static String GetOneIndex(String OneIndexTxt)
        {
if (Convert.ToChar(OneIndexTxt) >= 0 && Convert.ToChar(OneIndexTxt) < 256)
return OneIndexTxt;
else
return GetGbkX(OneIndexTxt);
        }

//根据汉字拼音排序得到首字母 
        private static string GetGbkX(string str)
        {
if (str.CompareTo("吖") < 0)
            {
return str;
            }
if (str.CompareTo("八") < 0)
            {
return "A";
            }

if (str.CompareTo("嚓") < 0)
            {
return "B";
            }

if (str.CompareTo("咑") < 0)
            {
return "C";
            }
if (str.CompareTo("妸") < 0)
            {
return "D";
            }
if (str.CompareTo("发") < 0)
            {
return "E";
            }
if (str.CompareTo("旮") < 0)
            {
return "F";
            }
if (str.CompareTo("铪") < 0)
            {
return "G";
            }
if (str.CompareTo("讥") < 0)
            {
return "H";
            }
if (str.CompareTo("咔") < 0)
            {
return "J";
            }
if (str.CompareTo("垃") < 0)
            {
return "K";
            }
if (str.CompareTo("呒") < 0)
            {
return "L";
            }
if (str.CompareTo("拏") < 0)
            {
return "M";
            }
if (str.CompareTo("噢") < 0)
            {
return "N";
            }
if (str.CompareTo("妑") < 0)
            {
return "O";
            }
if (str.CompareTo("七") < 0)
            {
return "P";
            }
if (str.CompareTo("亽") < 0)
            {
return "Q";
            }
if (str.CompareTo("仨") < 0)
            {
return "R";
            }
if (str.CompareTo("他") < 0)
            {
return "S";
            }
if (str.CompareTo("哇") < 0)
            {
return "T";
            }
if (str.CompareTo("夕") < 0)
            {
return "W";
            }
if (str.CompareTo("丫") < 0)
            {
return "X";
            }
if (str.CompareTo("帀") < 0)
            {
return "Y";
            }
if (str.CompareTo("咗") < 0)
            {
return "Z";
            }
return str;
        } 

    }
}






(2)讲获取的拼音缩写串存和RegionInfo类形成一个新类，软后按拼音缩写串排序。这样记录也排序了。代码如下：






  regionList = lo.Entities.ToList();
                FilterBuildingFromRegion(regionList);
foreach (RegionInfo regionInfo in regionInfoModel.RegionInfoOC)
                {
                    RegionInfo tempRegionInfo = new RegionInfo();
                    strPY = ChineseConvertToLetter.UtilIndexCode(regionInfo.RegionName);
                    tempRegionInfo = regionInfo;
                    tempRegionInfo.OrderKeyLetter = strPY;
                    tempRegionInfoOC.Add(tempRegionInfo);
                }               

                regionTree.ItemsSource =tempRegionInfoOC.OrderBy(p=>p.OrderKeyLetter);
