我有一些 js 来获取以英国时区显示的本地时间。
var d = new Date(); // local system time (whatever timezone that is)
var dUK = new Date(d.toLocaleString('en-GB', { timeZone: 'Europe/London' })); // UK timezone (covers BST too)

在除 IE 11(sigh...) 之外的所有浏览器中都可以正常工作,它会引发以下错误:
Option value 'EUROPE/LONDON' for 'timeZone' is outside of valid range. Expected: ['UTC']
有人有什么建议吗?有关支持 IE 的示例小提琴,请参见http://jsbin.com/dawaqocuvi/1/edit?html,js,console,output。

给定以下对象:
public class Person
{
public string Name {get; set;}
public string Age {get; set;}
public list<string> Interests {get; set;}
}

是否有一种很好的单行 linq 方法来展平它(我对扩展方法持开放态度),例如,如果我们有
var People = new List<Person>(){
new Person(){
Name = "Bill",
Age = 40,
Interests = new List<string>(){"Football", "Reading"}
},
new Person = new List<Person>(){
Name = "John",
Age = 32,
Interests = new List<string>(){ "Gameshows", "Reading"}
},
new Person = new List<Person>(){
Name = "Bill",
Age = 40,
Interests = new List<string>(){ "Golf"}
}
}

从命令行运行时,它工作正常,所以我认为这只是Task Runner Explorer的问题。
想象一下这样的事情......
public class Result
{
public string Name {get; set;}
public int Score {get; set;}
public bool Pass {get; set;}
}

还有一个静态方法...
public static Result SetPass(this Result result)
{
result.Pass = result.Score > 50;
return result;
}

我的问题是我必须返回结果还是已经修改到位?我可以让返回类型为空,然后遍历结果集合并像这样修改......
foreach (var result in results)
{
result.SetPass();
}

还是我需要返回结果对象并重新分配?
我有以下字符串......
{
"Qualifications[0].DegreeType": "Degree Type 1",
"Qualifications[0].Classification": "Clasification 1",

有没有人知道将其转换为javascript对象的简单方法,以便我可以有效地去...

我能想到的唯一方法是使用字符串操作和类似下面的东西,但是它需要为每个属性进行大量的自定义代码检查映射,而且我需要更通用和简单的东西....
let i = 0;
while (Qualifications[" + i +"].whateverProperty..) {
//add to object array
i++;
