[英]overload Equals, is this wrong?
Reading some piece of code and I keep seeing this : 阅读一些代码,我一直看到:
public override bool Equals (object obj)
{
if (obj == null || this.GetType ().Equals (obj.GetType())) return false;
//compare code...
}
Shouldn't it be like this (note the !): 它不应该像这样(注意!):
public override bool Equals (object obj)
{
if (obj == null || !this.GetType ().Equals (obj.GetType())) return false;
//compare code...
}
Or does the equals perform differently in this case? 还是在这种情况下平等表现不同?
That looks like a bug. 这看起来像一个bug。 Returning false when the types are the same is certainly not the intended behaviour.
类型相同时返回false当然不是预期的行为。
