我在xrm.saveChanges（）]上报错，如果我在AddObject正常工作的情况下执行UpdateObject，则最初我认为这是由于此线程Dynamics CRM saving Entity Changes - Getting Errors中讨论的上下文所致但我尝试了此处讨论的所有选项https://msdn.microsoft.com/en-us/library/gg695783.aspx，但没有任何帮助。
我的代码是`
using (var xrm = new XrmServiceContext("Xrm")) { WriteExampleContacts(xrm); //Create a new contact called Allison Brown. var allisonBrown = new Xrm.Contact { FirstName = "Allison", LastName = "Brown", Address1_Line1 = "23 Market St.", Address1_City = "Sammamish", Address1_StateOrProvince = "MT", Address1_PostalCode = "99999", Telephone1 = "12345678", EMailAddress1 = "[email protected]" }; xrm.AddObject(allisonBrown); xrm.SaveChanges(); WriteExampleContacts(xrm); //Update the e-mail address of Allison Brown and link her to the account Contoso. //allisonBrown.contact_customer_accountsParentCustomerAccount = account; using (var xrm2 = new XrmServiceContext("Xrm")) { xrm.Detach(allisonBrown); xrm2.Attach(allisonBrown); allisonBrown.EMailAddress1 = "[email protected]"; xrm2.UpdateObject(allisonBrown); xrm2.SaveChanges(); } //Update the contact record and then commit the changes to Microsoft Dynamics CRM. } Console.WriteLine("Press any key to exit."); Console.ReadKey(); } /// <summary> /// Use all contacts where the email address ends in @example.com. /// </summary> private static void WriteExampleContacts(XrmServiceContext xrm) { var exampleContacts = xrm.ContactSet .Where(c => c.EMailAddress1.EndsWith("@example.com")); //Write the example contacts. foreach (var contact in exampleContacts) { Console.WriteLine(contact.FullName); } }我得到的错误是

我在xrm.saveChanges（）上报错，如果我在AddObject正常工作的情况下执行UpdateObject，则最初我认为这是因为此线程中讨论的上下文，因为Dynamics CRM保存了实体更改...
