在asp.net中怎么实现拼音码查询

这个可以得到拼音
由于一个公司的OA上用到速查编码，必须得到每个字的首字母，便于以后的查询（如：开发部,则为KFB），到网上找到了一些资料，是一个存储过程。
存储过程为：
CREATE proc LOG_FindCode
@strName nvarchar(20),
@strFindCode nvarchar(20) output
as
begin
declare @word nchar(1),@PY nvarchar(4000)
set @PY=''
while len(@strName)>0
begin
set @word=left(@strName,1)
set @PY=@PY+(case when unicode(@word) between 19968 and 19968+20901
then (select top 1 PY from (
select 'A' as PY,N'驁' as word
union all select 'B',N'簿'
union all select 'C',N'錯'
union all select 'D',N'鵽'
union all select 'E',N'樲'
union all select 'F',N'鰒'
union all select 'G',N'腂'
union all select 'H',N'夻'
union all select 'J',N'攈'
union all select 'K',N'穒'
union all select 'L',N'鱳'
union all select 'M',N'旀'
union all select 'N',N'桛'
union all select 'O',N'漚'
union all select 'P',N'曝'
union all select 'Q',N'囕'
union all select 'R',N'鶸'
union all select 'S',N'蜶'
union all select 'T',N'籜'
union all select 'W',N'鶩'
union all select 'X',N'鑂'
union all select 'Y',N'韻'
union all select 'Z',N'咗'
) T
where word>=@word collate Chinese_PRC_CS_AS_KS_WS
order by PY ASC) else @word end)
set @strName=right(@strName,len(@strName)-1)
end
set @strFindCode=@PY
end

下面是把汉语传入，调用存储过程得到速查编码的方法

public string GetPY(string Name)//得到速查编码
{
SqlCommand cmd=new SqlCommand();
cmd.CommandType=CommandType.StoredProcedure;//类型为存储过程
cmd.CommandText="LOG_FindCode";//已经创建好的存储过程名
cmd.Connection=con;
con.Open();
SqlParameter parName=new SqlParameter();
parName.ParameterName="@strName";
parName.SqlDbType=SqlDbType.NVarChar;
parName.Size=20;
parName.Value=Name;

SqlParameter parMsg=new SqlParameter();
parMsg.ParameterName="@strFindCode";
parMsg.Direction=ParameterDirection.Output;
parMsg.SqlDbType=SqlDbType.NVarChar;
parMsg.Size=50;
cmd.Parameters.Add(parName);
cmd.Parameters.Add(parMsg);

cmd.ExecuteReader();
string strFindCode=parMsg.Value.ToString();
con.Close();
return strFindCode;
}

在程序代码中定义一个公共转换的方法就行了:::)
public static string GetPinYin(string str1)
{
string str2="";
byte[] array = new byte [2];
for(int i=0;i<str1.Length;i++)
{
array = System.Text.Encoding.Default.GetBytes(str1[i].ToString());
int aa=array[0];

if(array[0]>=176 && array[0]<=215) //一级汉字
{

if (str1[i].ToString ().CompareTo ("匝")>=0)
str2 += "z";
else if (str1[i].ToString ().CompareTo ("压")>=0)
str2 += "y";

str2 += "x";
