MbUnit Assert.AreEqual DateTime 和 Decimal 不等于
我有一个像这样的类结构
public class Entity
{
public int Id { get; set; }
public string Label { get; set; }
public string Description { get; set; }
public DateTime CreatedAt { get; set; }
public DateTime ModifiedAt { get; set; }
public DateTime? DeletedAt { get; set;
}
，我填充所有属性并将其保存到数据库，之后我从数据库获取该对象
var entity = CreateEntity()
SaveToDB(entity);
var entityFromDb = GetFromDB();
并尝试以这种方式比较值
Assert.AreEqual(entity, entityFromDb);
上比较失败
，但在日期时间和十进制值预期值 平等。
期望值： ID = 28， 创建时间 = 2011-01-05T14:06:32。6874218Z, 删除于 = null, 描述=“描述”， 持续时间=2000m， 标签=“测试实体”， 修改时间 = 2011-01-05T14:06:32.6874218Z
实际值： ID = 28， 创建时间 = 2011-01-05T14:06:32。0000000, 删除于 = null, 描述=“描述”， 持续时间 = 2000.00000m, 标签=“测试实体”， ModifiedAt = 2011-01-05T14:06:32.0000000
我可以以某种方式比较这些值，但不比较每个字段
I have a class structure like this
public class Entity
{
public int Id { get; set; }
public string Label { get; set; }
public string Description { get; set; }
public DateTime CreatedAt { get; set; }
public DateTime ModifiedAt { get; set; }
public DateTime? DeletedAt { get; set;
}
I fill all the properties and save it to the DB, after that I get this object from the DB
var entity = CreateEntity()
SaveToDB(entity);
var entityFromDb = GetFromDB();
and try to compare the values in this way
Assert.AreEqual(entity, entityFromDb);
and the comparison is faild on the DateTime and Decimal values
Expected values to be equal.
Expected Value :
Id = 28,
CreatedAt = 2011-01-05T14:06:32.6874218Z,
DeletedAt = null,
Description = "Description",
Duration = 2000m,
Label = "Test Entity",
ModifiedAt = 2011-01-05T14:06:32.6874218Z
Actual Value :
Id = 28,
CreatedAt = 2011-01-05T14:06:32.0000000,
DeletedAt = null,
Description = "Description",
Duration = 2000.00000m,
Label = "Test Entity",
ModifiedAt = 2011-01-05T14:06:32.0000000
Can I compare this values in some way, but without make a comparison of each fields

一种选择是更改 DateTimes 的设置器，以便它们在该点执行截断 - 基本上问题是您的数据库没有存储亚秒精度，因此在实体中也不包含它似乎是合理的。
我希望十进制值已经被比较为相等，即使它们具有不同的存储精度。 （1.000m 和 1.0m 有不同的表示方法，但被视为相等。）
One option would be to change your setters for DateTimes so that they perform the truncation at that point - basically the problem is that your DB isn't storing subsecond precision, so it seems reasonable not to have it in the entity either.
I'd expect the decimal values to be compared as equal already, even though they have different stored precision. (1.000m and 1.0m have different representations, but are deemed equal.)
