C＃比较两个强类型列表

如何解决C＃比较两个强类型列表

我强烈列出了数据，我想找到数据上的差异。我使用了EXCEPT，但在我只希望收到的地方得到了所有结果

expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "[e-mail]",IsEmailValid = false,ValidityChecked = true });

我想实现以下几点；

1-如果两个列表数据都相等？ 2-记录的差异

电子邮件类别

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 = "[e-mail]",IsEmailValid = true,ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "[e-mail]",ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "[e-mail]",ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail",ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail2@hotmail",ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "testemail3.com",ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "ccccc.com",ValidityChecked = true });
        expectedEmailValidationDtoList.Add(new EmailValidationDto { EmailAddress = "[e-mail]",ValidityChecked = true });

        var expectedEmailValidationDtoList2 = new List<EmailValidationDto>();

        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "[e-mail]",ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "[e-mail]",ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "[e-mail]",ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "testemail",ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "testemail2@hotmail",ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "testemail3.com",ValidityChecked = true });
        expectedEmailValidationDtoList2.Add(new EmailValidationDto { EmailAddress = "ccccc.com",ValidityChecked = true });


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

解决方法

您可以使用如下所示的Where（）和Any（）来比较两个列表：

    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)));
