比较两个相同的字符串列表

Question

Let's say I have following code:

    List<string> numbers = new List<string> { "1", "2" };
    List<string> numbers2 = new List<string> { "1", "2"};

    if (numbers.Equals(numbers2))
    {

    }

Like you can see I have two lists with identical items. Is there a way to check if these two lists are equal by using one method?

SOLUTION:

Use SequenceEqual()

Thanks

Answer 1

使用Enumerable.SequenceEqual ，但首先对列表进行Sort 。

Answer 2

// if order does not matter
bool theSame = numbers.Except(numbers2).Count() == 0;

// if order is matter
var set = new HashSet<string>(numbers);
set.SymmetricExceptWith(numbers2);
bool theSame = set.Count == 0;
