如何获得以某个字母开头的结果?

问题描述

我有一个类似于下面的方法，我需要返回所有以我传入的字母开头的组:

I have a method similar to the following, which I need to return all Groups that begin with the letter I'm passing in:

public IList<CompanyGroupInfo> GetGroupByQuery(string letter)
{
    IList<CompanyGroupInfo> result = null;

    result = _session
        .CreateCriteria<CompanyGroupInfo>()
        .Add(SqlExpression.Like<CompanyGroupInfo>(g => g.Name, letter))
        .List<CompanyGroupInfo>();

    return (result.Count > 0) ? result[0] : null;
}

我是 NHibernate 的新手，所以我真的不知道在这里做什么.在我看来，如果有一个 SqlExpression.StartsWith 方法是理想的，但没有.是否像修改表达式一样简单，以便

I'm brand new to NHibernate, so I don't really know what to do here. In my mind, it'd be ideal if there was a SqlExpression.StartsWith method, but there isn't. Is it as simple as modifying the expression so that

        .Add(SqlExpression.Like<CompanyGroupInfo>(g => g.Name, letter))

变得像

        .Add(SqlExpression.Like<CompanyGroupInfo>(g => g.Name.StartsWith(letter)))

有人能指出我正确的方向吗?谢谢

Can somebody please point me in the right direction? Thanks

推荐答案

只看文档，我怀疑你想要:

SqlExpression.Like<CompanyGroupInfo>(g => g.Name, letter, MatchMode.Start)

但我很久没有使用 NHibernate...

but I haven't used NHibernate for ages...
