nhibernate调用mysql函数问题 - .NET技术 / C#

我需要使用nhibernate调用mysql函数，类似的sql语句：
select * from concat(',', ServiceCodes, ',') like '%,33,%';
或select * from (','||ServiceCodes||',') like '%,33,%';

所以我就这样调用：
//.....
C# code:

or.Add(Restrictions.Like(Projections.SqlFunction("concat", NHibernateUtil.String, Projections.Property("ServiceCodes")), "%," + item + ",%"));


//....

Projections.SqlFunction函数第三个参数是params IProjection[] projections，但是对于逗号(,)我不知道怎么创建IProjection类似。


请各位指教。。。

select * from concat(',', ServiceCodes, ',') like '%,33,%';
或select * from (','||ServiceCodes||',') like '%,33,%';

->

select * from table where concat(',', ServiceCodes, ',') like '%,33,%';
或select * from table where (','||ServiceCodes||',') like '%,33,%';
