這個方法比較簡單，用Microsoft.VisualBasic命名空間下強大的字符串處理函數(shù)就可以了
c#代碼如下，編譯為BigConvertor.dll
--------------------------------------------------------------------------------
復(fù)制代碼 代碼如下:
using System;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
public partial class UserDefinedFunctions
{
[Microsoft.SqlServer.Server.SqlFunction ]
public static SqlString BigToGB(SqlString inString)
{
if (inString.IsNull) return SqlString .Null;
return (Microsoft.VisualBasic.Strings .StrConv(inString.Value, Microsoft.VisualBasic.VbStrConv .SimplifiedChinese, 0));
}
[Microsoft.SqlServer.Server.SqlFunction ]
public static SqlString GBToBig(SqlString inString)
{
if (inString.IsNull) return SqlString .Null;
return (Microsoft.VisualBasic.Strings .StrConv(inString.Value, Microsoft.VisualBasic.VbStrConv .TraditionalChinese, 0));
}
};
--------------------------------------------------------------------------------
部署代碼如下
--------------------------------------------------------------------------------
復(fù)制代碼 代碼如下:
CREATE ASSEMBLY BigConvertor FROM 'E:/sqlclrdata/BigConvertor.dll' WITH PERMISSION_SET = UnSAFE;
--
go
CREATE FUNCTION dbo. xfn_BigToGB
(
@value nvarchar ( max )
)
RETURNS nvarchar ( max )
AS EXTERNAL NAME BigConvertor. UserDefinedFunctions. BigToGB
go
CREATE FUNCTION dbo. xfn_GBToBig
(
@value nvarchar ( max )
)
RETURNS nvarchar ( max )
AS EXTERNAL NAME BigConvertor. UserDefinedFunctions. GBToBig
go
--------------------------------------------------------------------------------
測試代碼如下
--------------------------------------------------------------------------------
/* 測試 */
select dbo. xfn_GBToBig( ' 簡體與繁體文的轉(zhuǎn)換 ' )
-- 簡體與繁體文的轉(zhuǎn)換
select dbo. xfn_BigToGB( ' 簡體與繁體文的轉(zhuǎn)換 ' )
-- 簡體與繁體文的轉(zhuǎn)換
