Telerik OpenAccess和where子句中的多个条件

Question

我刚刚写了一些单元测试，令我感到恐惧的是它失败了。

这是我的测试...

[TestMethod]
public void FetchWithMoreThanOneConditionUsingKnownTypes() 
{
  using (var scope = EntityObjectScopeProvider.GetNewObjectScope()) 
  {
    var temp = new TempClient() { FirstName = "Rohan", Surname = "West" }; 
    var entity = scope.Extent<ClientEntity>().Where(c => temp.FirstName == c.FirstName && temp.Surname == c.Surname).FirstOrDefault(); 

    Assert.IsNotNull(entity);
    Assert.AreEqual(entity.FirstName, temp.FirstName); 
    Assert.AreEqual(entity.Surname, temp.Surname); 
  }
}

它给了我以下异常，无法将类型为'Entities.Testing.TempClient'的对象强制转换为'System.String'。这是正常的，我希望不是，以下测试正常。我猜解析表达式时会出现问题...这会被解决吗？

[TestMethod]
public void FetchWithMoreThanOneConditionUsingTempVariables() 
{
  using (var scope = EntityObjectScopeProvider.GetNewObjectScope()) 
  {
    var temp = new TempClient(){ FirstName = "Rohan", Surname = "West" };   

    string firstname = temp.FirstName; 
    string surname = temp.Surname; 

    var entity = scope.Extent<ClientEntity>().Where(c => c.FirstName == firstname && c.Surname == surname).FirstOrDefault(); 

    Assert.IsNotNull(entity);
    Assert.AreEqual(entity.FirstName, temp.FirstName);
    Assert.AreEqual(entity.Surname, temp.Surname); 
  }
}

在联系Telerik支持后，结果证明不可能。
