LINQ实体错误使用SequenceEqual枚举方法

Question

我有以下LINQ声明（的stationID是int和版本是一个字节数组）：

  var foundStation = (from wd in _Context.AssignmentWizardDatas 
       from station in wd.AssignmentWizardStationDatas 
       where station.Id == stationId 
       where station.Version.SequenceEqual(version) 
       select station).SingleOrDefault(); 

当上述代码运行我会遇到以下错误：

LINQ to Entities does not recognize the method 'Boolean SequenceEqual[Byte](System.Collections.Generic.IEnumerable 1[System.Byte], System.Collections.Generic.IEnumerable 1[System.Byte])' method, and this method cannot be translated into a store expression.

经过一番阅读后，我意识到问题是LINQ无法将SequenceEqual方法调用转换为SQL等价物（我认为无论如何）。有没有人知道这个解决方法？或者，当尝试在LINQ查询中使用字节数组时，可能会指向正确的方向，但我找不到专门用于字节数组的现有问题。

在此先感谢。

编辑：使用贾尼的职位，这是用来解决这个错误最终代码：

 //eager execution of the linq query to find the stations 
    var foundStation = (from wd in _Context.AssignmentWizardDatas 
          from station in wd.AssignmentWizardStationDatas 
          where station.Id == stationId 
          select station).ToList(); 
    //finding the result in memory 
     var result = (from f in foundStation 
         where f.Version.SequenceEqual(version) 
         select f).SingleOrDefault(); 

Answer 1

//eager execution of the linq query to find the stations 
var foundStation = (from wd in _Context.AssignmentWizardDatas 
        where wd.Id == stationId 
        select station).ToList(); 
//finding the result in memory 
var result = from f in foundStation 
      where f.version.SequenceEqual(version) 
      select f;

您在您解释的错误的方式是正确的，但你并不需要SequenceEquals()完全可以 - 您可以直接比较数据库中提供的绑定到varbinary(MAX)的字节数组。

var foundStation = (from wd in _Context.AssignmentWizardDatas 
from station in wd.AssignmentWizardStationDatas 
where station.Id == stationId 
where station.Version == version 
select station).SingleOrDefault();
