C# – Httputility.urldecode replacement in .Net4

.net-2.0.net-4.0cencodingsystem.web

I got an old Program(class library) developed by .Net 2. Recently I want to use that Program in new project which is use .Net4(For new WPF feature's ). so there is a big problem:

.Net4 don't support System.Web and as result it can't be use Httputility.urldecode!!

So what is urldecode jop? and how can I change that to something, which is support by .Net4?

HttpUtility is wild goose chase for c# users since it's not already there (referenced)
2 alternatives :

  string a =  System.Uri.EscapeUriString("https://some.url.goes.here"); // for path
  string b = System.Uri.EscapeDataString("parameter1=1&parameter2=something"); // for params

Scala: list.flatten: no implicit argument matching parameter type (Any) = > Iterable[Any] was found

If you are expecting to be able to "flatten" List(1, 2, List(3,4), 5) into List(1, 2, 3, 4, 5), then you need something like:

implicit def any2iterable[A](a: A) : Iterable[A] = Some(a)

Along with:

val list: List[Iterable[Int]] = List(1, 2, List(3,4), 5) // providing type of list 
                                                         // causes implicit 
                                                         // conversion to be invoked

println(list.flatten( itr => itr )) // List(1, 2, 3, 4, 5)

EDIT: the following was in my original answer until the OP clarified his question in a comment on Mitch's answer

What are you expecting to happen when you flatten a List[Int]? Are you expecting the function to sum the Ints in the List? If so, you should be looking at the new aggegation functions in 2.8.x:

val list = List(1, 2, 3)
println( list.sum ) //6
