这个方法比较简单，用Microsoft.VisualBasic命名空间下强大的字符串处理函数就可以了c#代码如下，编译为BigConvertor.dll--------------------------------------------------------------------------------
复制代码 代码如下:
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));
}
};
--------------------------------------------------------------------------------部署代码如下--------------------------------------------------------------------------------
复制代码 代码如下:
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
--------------------------------------------------------------------------------测试代码如下 --------------------------------------------------------------------------------
/* 测试 */
select dbo. xfn_GBToBig( ' 简体与繁体文的转换 ' )
