是否可以比较 "North, South, East" 和 "North, East, South" 并找到等价性？

Question

是否可以比较两个字符串，例如：

"North, South, East" == "North, East, South"

并根据

这一事实找到等价性

both contain "North"

或

both contain "South"

另一个例子

"North" == "North, South"

还有

"North" != "South"

显然逗号分隔了用于比较的关键字符串。不确定 C# 中是否有一个关键函数可以帮助解决这个问题？ "Contains" 将不起作用，因为分隔值的顺序可能不同，即

"North, South" == "South, North"

如有任何帮助，我们将不胜感激。正在寻找 C# 专家指导！

Answer 1

使用 String.Split 从 String 中获取 string[]，其中每个标记由分隔符分隔，例如逗号：

var tokens1 = "North, South, East".Split(',').Select(s => s.Trim());
var tokens2 = "North, East, South".Split(',').Select(s => s.Trim());

我已经使用 Enumerable.Select 删除了 String.Trim 的前导或尾随空格。现在你可以使用 Intersect + Any 来检查是否有公共交集：

bool anyIntersection = tokens1.Intersect(tokens2).Any();

Answer 2

你可以这样写 Any():

string NEWS = "North, South, East";
string NEW = "North, East, South";

var temp1 = NEWS.Split(',');
var temp2 = NEW.Split(',');

if (temp1.Any(x => temp2.Contains(x)))
{
 // means equal
}

Answer 3

你的意思是这样的，它打印 "Strings in common: South, East"

string s1 = "North, South, East";
string s2 = "East, West, South";

var strings1 = s1.Split(',').Select(s => s.Trim());
var strings2 = s2.Split(',').Select(s => s.Trim());

var stringsInCommon = strings1.Intersect(strings2);

Console.WriteLine("Strings in common: " + string.Join(", ", stringsInCommon));

是否可以比较 "North, South, East" 和 "North, East, South" 并找到等价性？

Is it possible to compare "North, South, East" and "North, East, South" and find equivalence?
