System.Linq.Dynamic.ParseException：'。' 或'（'预期-VS2012错误

Question

I have trying to run the following code:

 [TestMethod]
 [TestCleanup]
 public void TestMethod3()
 {
      using (var context = new CorporateDWTestEntities1())
      {
          //Deleting every row within the OLE_DB_Destination1 table.
          var query = from c in context.SRS_Ticket_Transaction_Stage select c;
          query.Delete();
          context.SaveChanges();
      }
 }

however when it runs, I recieve an error message that states:

"Message:Test method Integration_Services_Tests.UnitTest1.TestMethod3 threw exception: System.Linq.Dynamic.ParseException: '.' or '(' expected Test cleanup method Integration_Services_Tests.UnitTest1.TestMethod3 threw exception. System.Linq.Dynamic.ParseException: System.Linq.Dynamic.ParseException:'.' or ')' expected."

Does anybody know what this means and how to overcome it?

Answer 1

According to this question , you might need to load all of the records into memory, then call context.SRS_Ticket_Transaction_Stage.DeleteOnSubmit() for each item:

[TestMethod]
[TestCleanup]
public void TestMethod3()
{
    using (var context = new CorporateDWTestEntities1())
    {
        //Deleting every row within the OLE_DB_Destination1 table.
        var query = from c in context.SRS_Ticket_Transaction_Stage select c;
        var records = query.ToList();

        foreach(var record in records) 
        {
            context.SRS_Ticket_Transaction_Stage.DeleteOnSubmit(record);
        }
        context.SubmitChanges();
    }
}
