我会像这样创建一个QueryOver
SELECT *
FROM Table
WHERE Field IN (1,2,3,4,5)
我尝试使用Contains
方法,但我遇到了异常
“System.Exception:无法识别的方法调用:System.String:Boolean包含(System.String)”
这是我的代码
var qOver = _HibSession.QueryOver<MyModel>(() => baseModel)
.JoinAlias(() => baseModel.Submodels, () => subModels)
.Where(() => subModels.ID.Contains(IDsSubModels))
.List<MyModel>();

我找到了解决方案!! : - )
var qOver = _HibSession.QueryOver<MyModel>(() => baseModel)
.JoinAlias(() => baseModel.Submodels, () => subModels)
.WhereRestrictionOn(() => subModels.ID).IsIn(IDsSubModels)
.List<MyModel>();

您可以尝试这样的事情:
// if IDsSubModels - array of IDs
var qOver = _HibSession.QueryOver<MyModel>()
.Where(x => x.ID.IsIn(IDsSubModels))
在这种情况下你不需要加入

这很有效,而且更优雅
var Strings = new List<string> { "string1", "string2" };
var value = _currentSession
.QueryOver<T>()
.Where(x => x.TProperty == value)
.And(Restrictions.On<T>(y=>y.TProperty).IsIn(Strings))
.OrderBy(x => x.TProperty).Desc.SingleOrDefault();
where T is a Class and TProperty is a property of T
