C# 比较两个强类型列表

Question

我有强烈的数据列表，我想找出数据中的差异。我已经使用了 EXCEPT，但我得到了我只希望收到的所有结果

expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail889@hotmail.com", IsEmailValid = false, ValidityChecked = true });

我想达到以下几点；

1- 两个列表数据是否相等？ 2- 记录差异

电子邮件Class

public class EmailValidationDto
{   
    public string EmailAddress { get; set; }
    public bool IsEmailValid { get; set; }
    public bool ValidityChecked { get; set; }
}

列表

var expectedEmailValidationDtoList = new List<EmailValidationDto>();

        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "Myemail@hotmail.com", IsEmailValid = true, ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "TestEmail009@hotmail.com", IsEmailValid = true, ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "devOps@hotmail.com", IsEmailValid = true, ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail", IsEmailValid = false, ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail2@hotmail", IsEmailValid = false, ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail3.com", IsEmailValid = false, ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "ccccc.com", IsEmailValid = false, ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail889@hotmail.com", IsEmailValid = false, ValidityChecked = true });

        var expectedEmailValidationDtoList2 = new List<EmailValidationDto>();

        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "khurram@hotmail.com", IsEmailValid = true, ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "TestEmail009@hotmail.com", IsEmailValid = true, ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "devOps@hotmail.com", IsEmailValid = true, ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "testemail", IsEmailValid = false, ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "testemail2@hotmail", IsEmailValid = false, ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "testemail3.com", IsEmailValid = false, ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "ccccc.com", IsEmailValid = false, ValidityChecked = true });


  var d1 = expectedEmailValidationDtoList.Except(expectedEmailValidationDtoList2).ToList();
  var d2 = expectedEmailValidationDtoList2.Except(expectedEmailValidationDtoList).ToList();

Answer 1

您可以使用如下所示的 Where() 和 Any() 来比较 2 个列表：

    var d1 = expectedEmailValidationDtoList1
        .Where(email1 => !expectedEmailValidationDtoList2
            .Any(email2 => email1.EmailAddress
                .Equals(email2.EmailAddress, StringComparison.InvariantCultureIgnoreCase)));
    var d2 = expectedEmailValidationDtoList2
        .Where(email1 => !expectedEmailValidationDtoList1
            .Any(email2 => email1.EmailAddress
                .Equals(email2.EmailAddress, StringComparison.InvariantCultureIgnoreCase)));

或使用 All()

    var d21 = expectedEmailValidationDtoList1
        .Where(email1 => expectedEmailValidationDtoList2
            .All(email2 => !email1.EmailAddress
                .Equals(email2.EmailAddress, StringComparison.InvariantCultureIgnoreCase)));
    var d22 = expectedEmailValidationDtoList2
        .Where(email1 => expectedEmailValidationDtoList1
            .All(email2 => !email1.EmailAddress
                .Equals(email2.EmailAddress, StringComparison.InvariantCultureIgnoreCase)));
