When using the Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> constructor to create an n-tuple with eight or more components, you use the rest parameter to create a nested n-tuple that has from one to seven components. By using successive levels of nesting, you can create an n-tuple that has...
Write a Scala program that creates a tuple from two lists. Sample Solution: Scala Code: objectTupleFromListsExample{defmain(args:Array[String]):Unit={// Create two listsvallist1=List("Red","Green","Blue")vallist2=List(1,3,5)// Print said two listsprintln("List1: "+list1)println("...
var tuple = Tuple.Create("foo"); Console.WriteLine(tuple.A); Why write a script to generate these classes? Wouldn't it just be easier to just do this by hand??? Yes and no. If you are doing a fixed set of short used classes then yes, do it by hand. These scripts evolved out...
但是,静态Tuple.Create方法不能用于创建具有八个以上组件的元组对象。 使用Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>构造函数创建具有八个或更多组件的 n 元组时,可以使用rest参数创建一个嵌套的 n 元组,该组具有一到七个组件。 通过使用连续的嵌套级别,可以创建具有几乎无限数量的组件的 n 元组。 例如,若要创建一...
总结一下,上面实现的原理是: 自定义一个OutputFormatter,在WriteResponseBodyAsync中,可以获取到当前的Action对应的MethodInfo,然后利用编译器在所有返回ValueTuple的地方,都加了TupleElementNamesAttribute的功能,获取到使用时定义的ValueTuple各个Item的名字,再利用ContractResolver的CreateProperty功能,将定义的各个Item转换为对...

Then, to retrieve the tuple, I retrieved the string, broke it into array and used the array to re-create a tuple. lettupleString = defaultsLoad.stringForKey("Tuple") iflettupleString = tupleString { lettupleArray = tupleString.componentsSeparatedByString(",") ...
