Question

我目前正在对复制功能进行一些单元测试，我需要比较旧列表和新复制列表之间的对象元素。它工作正常，但我想知道我是否可以以不涉及for循环的方式来完成它。这是我的目标：

new NaturePointObject
            {
                SId = 1,
                Name = "Test",
                Category = NaturePointCategory.Category1,
                CreatorType = CreatorTypeEnum.1,
                NaturR = NaturR.Bn,
                Description = "Test",
                Kumulation = Kumulation.EnEjendom,
                Id = 1
            }

我的旧列表包含＆＃34; NaturePointObject＆＃34;并被称为naturPointList，它将被复制到名为newNaturePointList的列表中。以下是我如何知道它是否成功复制：

Assert.AreEqual(naturPointList.Count,newNaturePointList.Count);
        for (var i = 0; i < newNatureList.Count; i++)
        {
            Assert.AreEqual(naturPointList[i].Category, newNaturePointList[i].Category);
            Assert.AreEqual(naturPointList[i].Description, newNaturePointList[i].Description);
            Assert.AreEqual(naturPointList[i].Kumulation, newNaturePointList[i].Kumulation);
            Assert.AreEqual(naturPointList[i].Name, newNaturePointList[i].Name);
            Assert.AreEqual(naturPointList[i].CreatorType, newNaturePointList[i].CreatorType);
            Assert.AreEqual(naturPointList[i].NaturR, newNaturePointList[i].NaturR);
            Assert.AreNotEqual(naturPointList[i].SId, newNaturePointList[i].SId);
        }

正如您所看到的，并非对象的所有元素都必须相等。而且我不在乎＆＃34; Id＆＃34;对象。

有没有比运行for循环更短的方法呢？

Answer 1

可能您想使用CollectionAssert.AreEqual(naturPointList, newNaturePointList, NaturePointObject.CategoryCreatorTypeComparer);：

IComparer

您唯一需要注意的是，您需要实施Assert，以便在public class NaturePointObject { private static readonly Comparer<NaturePointObject> CategoryCreatorTypeComparerInstance = new CategoryCreatorTypeRelationalComparer(); private sealed class CategoryCreatorTypeRelationalComparer : Comparer<NaturePointObject> { public override int Compare(NaturePointObject x, NaturePointObject y) { // compare fields which makes sense if (ReferenceEquals(x, y)) return 0; if (ReferenceEquals(null, y)) return 1; if (ReferenceEquals(null, x)) return -1; var categoryComparison = string.Compare(x.Category, y.Category, StringComparison.Ordinal); if (categoryComparison != 0) return categoryComparison; return string.Compare(x.CreatorType, y.CreatorType, StringComparison.Ordinal); } } public static Comparer<NaturePointObject> CategoryCreatorTypeComparer { get { return CategoryCreatorTypeComparerInstance; } } public int SId { get; set; } public string Category { get; set; } //other properties public string CreatorType { get; set; } }方法中使用：

select * from 
sysobjects, syscomments
WHERE sysobjects.id = syscomments.id and type='tr'
and text like '%AFTER UPDATE%'

Answer 2

你可以尝试

Assert.IsTrue(naturPointList.SequenceEqual(newNaturePointList));

如果你想忽略Id，你可以创建其他类（没有ID）。

稍后编辑：您可以覆盖Equals方法并忽略Id。

Assert Equal两个对象列表UnitTesting c＃
