Telerik OpenAccess 和 where 子句中的多个条件 [英] Telerik OpenAccess and multiple conditions in the where clause

问题描述

我刚刚编写了一些单元测试，但令我震惊的是它失败了.

I have just written a few unit tests and to my horror it failed.

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Entities.Testing.TempClient"类型的对象转换为System.String".这是否正常，我希望不是，以下测试正常工作.估计是在解析表达式的时候有问题...会解决这个问题吗?

it is giving me the following exception, Unable to cast object of type 'Entities.Testing.TempClient' to type 'System.String'. Is this normal, i hope not, The following test works correctly. I guess there is a problem when parsing the expression... Will this be fixed?

[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); 
  }
}

推荐答案

在联系 Telerik 支持后，结果证明这是不可能的.

After contacting Telerik support, it turned out not to be possible.
