Question

班级定义：

Dictionary<int, HubObject> result

我的Key Value 0 {Hub={"Hub0", 600}, Sites={{"Chicago", 100}, {"Minneapolis", 200}, {"Newyork", 300}}} 1 {Hub={"Hub1", 300}, Sites={{"Portland", 100}, {"Santaclara", 200}}}包含..

List<List<string>>

希望以下面的格式将其转换为"SiteId", "Value" "Hub0", 600 "Chicago", 100 "Minneapolis", 200 "Newyork", 300 "Hub1", 300 "Portland", 100 "Santaclara", 200。

var sitesList = result.SelectMany(r => r.Value.Sites.Select(x => new
                {
                    x.SiteId,
                    x.Value
                })).ToList();

这是我迄今取得的成就

"SiteId",   "Value"
"Chicago", 100
"Minneapolis", 200
"Newyork", 300
"Portland", 100
"Santaclara", 200

这给了我......

Hub0

如何为此添加“Hub”行？比如，第一个WebElement element = driver.findElement(By.id("id-home_prevButton"); ((JavascriptExecutor)driver).executeScript("arguments[0].click();", element);父项后面跟着它所属的所有网站，依此类推。

我认为你可以这样做：

var sitesList=result.SelectMany(r => 
    {
        return r.Value.Sites
           .Concat(new List<Site>{r.Value.Hub})
           .Select (s =>new{s.SiteId,s.Value});
    });

你甚至可以这样做：

var sitesList=result.SelectMany(r => 
            new List<Site>{r.Value.Hub}.Concat(r.Value.Sites)
               .Select (s =>new{s.SiteId,s.Value}));

LINQ：将Dictionary <int，object =“”>转换为List <list <string>＆gt;
