NUnit'；对于自定义类的类似列表，s CollectionAssert返回false

本文关键字：列表 CollectionAssert false 返回 NUnit 自定义 | 更新日期: 2023-09-27 18:27:25

这是我的类：

public class MyClass
{
    public string Name { get; set; }
    public string FaminlyName { get; set; }
    public int Phone { get; set; }
}

然后我有两个类似的列表：

List<MyClass> list1 = new List<MyClass>()
{
    new MyClass() {FaminlyName = "Smith", Name = "Arya", Phone = 0123},
    new MyClass() {FaminlyName = "Jahani", Name = "Shad", Phone = 0123}
};
List<MyClass> list2 = new List<MyClass>()
{
    new MyClass() {FaminlyName = "Smith", Name = "Arya", Phone = 0123},
    new MyClass() {FaminlyName = "Jahani", Name = "Shad", Phone = 0123}
};

问题是NUnit CollectionAssert总是返回false。

CollectionAssert.AreEqual(list1,list2);

我是否遗漏了CollectionAssert测试的某些内容

AreEqual检查对象是否相等。由于您没有重写Equals方法，如果引用不相等，它将返回false。

您可以通过重写MyClass:的Equals方法来解决此问题

public class MyClass {
    public string Name { get; set; }
    public string FaminlyName { get; set; }
    public int Phone { get; set; }
    public override bool Equals (object obj) {
         MyClass mobj = obj as MyClass;
         return mobj != null && Object.Equals(this.Name,mobj.Name) && Object.Equals(this.FaminlyName,mobj.FaminlyName) && Object.Equals(this.Phone,mobj.Phone);
    }
}

此外，您还可以更好地覆盖GetHashCode方法：

public class MyClass {
    public string Name { get; set; }
    public string FaminlyName { get; set; }
    public int Phone { get; set; }
    public override bool Equals (object obj) {
         MyClass mobj = obj as MyClass;
         return mobj != null && Object.Equals(this.Name,mobj.Name) && Object.Equals(this.FaminlyName,mobj.FaminlyName) && Object.Equals(this.Phone,mobj.Phone);
    }
    public override int GetHashCode () {
        int hc = 0x00;
        hc ^= (this.Name != null) ? this.Name.GetHashCode() : 0;
        hc ^= (this.FaminlyName != null) ? this.FaminlyName.GetHashCode() : 0;
        hc ^= this.Phone.GetHashCode();
        return hc;
    }
}
