检查对象 HashSet 的相等性

我正在尝试比较两个哈希集Definition输入为EqualityComparer<T>.Default.Equals(value, oldValue). Definition定义如下

public class Definition
{
    public string Variable { get; set; }
    public HashSet<Location> LocationList { get; set; }

    public override bool Equals(object obj)
    {
        Definition other = obj as Definition;
        return other.Variable.Equals(this.Variable) && other.LocationList!= null &&this.LocationList != null
            && other.LocationList.Count == this.LocationList.Count
            && other.LocationList == this.LocationList;
    }

    public override int GetHashCode()
    {
        return this.Variable.GetHashCode() ^ this.LocationList.Count.GetHashCode();// ^ this.LocationList.GetHashCode();
    }
}

public class Location
{
    public int Line { get; set; }
    public int Column { get; set; }
    public int Position { get; set; }
    public string CodeTab { get; set; }
    public Location(int line, int col, int pos, string tab)
    {
        Line = line;
        Column = col;
        Position = pos;
        CodeTab = tab;
    }
    public override bool Equals(object obj)
    {
        Location other = obj as Location;
        return this.CodeTab == other.CodeTab
            && this.Position == other.Position
            && this.Column == other.Column
            && this.Line == other.Line;
    }
    public override int GetHashCode()
    {
        return this.CodeTab.GetHashCode() ^ this.Position.GetHashCode() 
            ^ this.Column.GetHashCode() ^ this.Line.GetHashCode();
    }
}

不知何故，对于相似的集合，结果返回为false尽管所有信息保持不变。唯一的区别是一些元素的位置互换了，但我知道HashSet比较时不会保留或检查顺序。任何人都可以告诉我这里出了什么问题吗？

PS：我尝试取消注释this.LocationList.GetHashCode()也，但没有用。

您需要为集合创建一个比较器：

var setComparer = HashSet<Location>.CreateSetComparer();
return other.Variable.Equals(this.Variable) && setComparer.Equals(this.LocationList, other.LocationList);
