这是我的班级:
public class Person { public string FirstName { get; set; } public string LastName { get; set; } public string FullName { get { return FirstName + " " + LastName; } } }
这是我的清单:
var persons = new List<Person>(); persons.Add(...); persons.Add(...); etc.
如果我尝试通过“计算”属性FullName搜索列表,如下所示:
return persons.Where(p => p.FullName.Contains("blah"))
我收到以下错误:
System.NotSupportedException: The specified type member ‘FullName’ is
not supported in LINQ to Entities. Only initializers,entity members,
and entity navigation properties are supported.
我怎么能绕过这个?
解决方法
在您的情况下,您只需更改您在何处使用计算属性的两个部分:
return persons.Where(p => (p.FirstName + " " + p.LastName).Contains("blah"))
