两个枚举之间的相等性 [英] Equality between two enumerables

问题描述

我有两个具有完全相同的参考元素的可枚举对象，想知道为什么Equals不正确.

I have two enumerables with the exact same reference elements, and wondering why Equals wouldn't be true.

作为附带的问题，下面的代码可以比较每个元素，但是必须有一种更优雅的方法

As a side question, the code below to compare each element works, but there must be a more elegant way

var other = (ActivityService) obj;
if (!AllAccounts.Count().Equals(other.AllAccounts.Count())) return false;
for (int i = 0; i < AllAccounts.Count(); i++) {
    if (!AllAccounts.ElementAt(i).Equals(other.AllAccounts.ElementAt(i))) {
        return false;
    }
}
return true;

推荐答案

看看根据数据类型，您可能还需要使用重载的方法接受IEqualityComparer定义自定义比较方法.

Depending on the data type you may also need to use the overloaded method that accepts an IEqualityComparer to define a custom comparison method.
