问题描述
我正在尝试这样做:
var list = Session.QueryOver<Person>()
.Where(x => x.LastName.Contains(searchText))
.List<Person>();
但我收到此错误:无法识别的方法调用:System.String:Boolean Contains(System.String)
你有什么想法吗?
更新:
public class Person
{
public virtual string FirstName { get; set; }
public virtual string LastName { get; set; }
}
推荐答案
NHibernate 没有此链接中提到的直接 C# 等效项 http://nhibernate.info/blog/2009/12/17/queryover-in-nh-3-0.html
NHibernate does not have direct C# equivalent as mentioned on this link http://nhibernate.info/blog/2009/12/17/queryover-in-nh-3-0.html
其他限制
某些 SQL 运算符/函数在 C# 中没有直接等效项.(例如,SQL where name like '%anna%').这些运营商有Restrictions 类中 QueryOver 的重载,因此您可以编写:
Some SQL operators/functions do not have a direct equivalent in C#. (e.g., the SQL where name like '%anna%'). These operators have overloads for QueryOver in the Restrictions class, so you can write:
.Where(Restrictions.On(c => c.Name).IsLike("%anna%"))
.Where(Restrictions.On(c => c.Name).IsLike("%anna%"))
还有一个内联语法来避免类型的限定:
There is also an inline syntax to avoid the qualification of the type:
.WhereRestrictionOn(c => c.Name).IsLike("%anna%")
.WhereRestrictionOn(c => c.Name).IsLike("%anna%")
