问题描述
下面的行创建一个名为ValueTuple的文件:
The following line creates a named ValueTuple:
var tuple = (a:1, b:2, c:3, d:4, e:5, f:6);
值类型不能有效地传递. C#7是否提供创建Tuple类型的命名元组的方法?
Value types can not be passed around efficiently. Does C#7 offer a way to create named tuples of the Tuple type?
推荐答案
如果您的意思是如果可以将其他名称附加到System.Tuple<...>实例的属性，则没有.
If you mean if there's a way to attach other names to the properties of System.Tuple<...> instances, no there isn't.
根据需要的原因，可以通过使用 TupleExtensions ，然后使用ToTuple重载.
Depending on why you want it, you might get around it by converting System.Tuple<...> instances to System.ValueTuple<...> instances using the ToValueTuple overloads in TupleExtensions and back using the ToTuple overloads.
如果您真的不需要元组，则可以使用Deconstruct重载或var (v1, .., vn) = tuple解构语法将它们解构为离散变量.
If you don't really need the tuples, you can deconstruct them into discrete variables using the Deconstruct overloads or the var (v1, .., vn) = tuple deconstruction syntax.
