是否可以在C#7中创建ValueTuple列表?

Is it possible to create a list of ValueTuple in C# 7?

像这样:

List<(int example, string descrpt)> Method() { return Something; }

推荐答案

您正在寻找这样的语法:

You are looking for a syntax like this:

List<(int, string)> list = new List<(int, string)>(); list.Add((3, "first")); list.Add((6, "second"));

您可以在这种情况下使用:

You can use like that in your case:

List<(int, string)> Method() => new List<(int, string)> { (3, "first"), (6, "second") };

您还可以在返回之前命名值:

You can also name the values before returning:

List<(int Foo, string Bar)> Method() => ...

您可以在(重新)命名它们时收到这些值:

And you can receive the values while (re)naming them:

List<(int MyInteger, string MyString)> result = Method(); var firstTuple = result.First(); int i = firstTuple.MyInteger; string s = firstTuple.MyString;
