var nums = new[]{ 1, 2, 3, 4, 5, 6, 7};
var pairs  = /* some linq magic here*/ ;

=> pairs = {{1,2},{3,4},{5,6},{7,0}}

元素pairs应该是两元素列表,或者是一些具有两个字段的匿名类的实例,例如new {First = 1, Second = 2}.

以下内容将- /分隔的URL路径解析为键/值对的字典：

    private Dictionary<string, string> ParsePathParameters(string path)
    {
        var parameters = new Dictionary<string, string>();
        if (string.IsNullOrEmpty(path))
        {
            return parameters;
        }

        var pathSegments = path.Split(new[] { '/' }, StringSplitOptions.RemoveEmptyEntries);

        for (var i = pathSegments.Length - 1; i >= pathSegments.Length % 2; i -= 2)
        {
            parameters.Add(pathSegments[i - 1], pathSegments[i]);
        }

        return parameters;
    }

输入格式是[/preamble][/key1/value1][/key2/value2]...[/keyN/valueN]这样的，例如，给定输入“ / foo / 1 / bar / Thing”或“ / slug / foo / 1 / bar / Thing”，输出将是：

Dictionary<string, string>
{
    { "foo", "1" …
