Unit的CollectionAssert对于类似的自定义类列表

Unit的CollectionAssert对于类似的自定义类列表

本文介绍了NUnit的CollectionAssert对于类似的自定义类列表返回false的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

这是我的课程:

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:

Then I have two similar list:

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.

The problem is that NUnit CollectionAssert return false always.

CollectionAssert.AreEqual(list1,list2);

我是否缺少有关CollectionAssert测试的一些信息

Am I missing something about CollectionAssert test

推荐答案

AreEqual 检查对象的相等性.由于您没有覆盖 Equals 方法,因此如果引用不相等,它将返回 false .

The AreEqual checks for equality of the objects. Since you did not override the Equals method, it will return false in case the references are not equal.

您可以通过覆盖 MyClass Equals 方法来解决此问题:

You can solve this by overriding the Equals method of your MyClass:

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);
    }

}

您还更好地重写了 GetHashCode 方法:

You furthermore better override the GetHashCode method as well:

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;
    }

}
