从另一个类中的一个方法返回两个带有元组的字典 [英] Returning two dictionaries with Tuple from one method within another class

问题描述

我有一个班级，AClass 班.在这个课程中，我正在填写两个字典，而且，我正在返回这两个字典，所以我使用了 Tuple, Dictionary> 类型的方法声明:

I have one class, class AClass. In this class I'm filling two dictionaries and also, I'm returning these two dictionaries so I've used Tuple<Dictionary<string, string>, Dictionary<string, string>> type of method declaration:

class AClass
{
    Dictionary<string, string> dictOne = new Dictionary<string, string>();
    Dictionary<string, string> dictTwo = new Dictionary<string, string>();

    public Tuple<Dictionary<string, string>, Dictionary<string, string>> MyMethodOne()
    {
        //Adding items dictOne and dictTwo

        return new Tuple<Dictionary<string, string>, Dictionary<string, string>>(dictOne, dictTwo);
    }
}

在其他类中，BClass 类，我应该获取这两个字典，访问它们并将它们的条目添加到另外两个字典中:

In other class, class BClass, I should get these two dictionaries, access them and add their items to another two dictionaries:

 class BClass
 {
    AClass _ac = new AClass();

    Dictionary<string, string> dictThree = new Dictionary<string, string>();
    Dictionary<string, string> dictFour = new Dictionary<string, string>();

    public void MyMethodTwo()
    {
    //Here I should get dictionaries through Tuple
    //Add items from dictOne to dictThree
    //Add items from dictTwo to dictFour
    //In a way
    //   foreach (var v in accessedDict)
    //   {
    //   dictThree.Add(v.Key, v.Value);
    //   }
    }
}

如果 MyMethodOne 只返回一本字典，我会知道如何将项目从一本字典获取到另一本字典，但这里我有 元组，我从未使用过它，并且我不知道如何获得这两个重新调整值.我应该这样做吗?还有另一种方法，也许将方法声明为 Dictionary<;字典<字符串，字符串>，字典<字符串，字符串>>?

If MyMethodOne was returning only one dictionary I would know how to get items from one dictionary to another but here I have Tuple, with which I have never worked, and I don't know how how to get these two retuning values. Should I do it like this at all? Is there another way, maybe to declare method as Dictionary< Dictionary<string, string>, Dictionary<string, string>>?

那么，如何从 Tuple 中获取字典?

So, how to get dictionaries from Tuple?

推荐答案

Tuple 类在名为Item(Number)"的属性中公开其成员:http://msdn.microsoft.com/en-us/library/dd289533.aspx

The Tuple class exposes its members in properties called "Item(Number)": http://msdn.microsoft.com/en-us/library/dd289533.aspx

因此，您的两项元组将具有名为 Item1 和 Item2 的属性:

So, your two-items Tuple will have properties called Item1 and Item2:

var dictionaries = _ac.MyMethodOne();
// now dictionaries.Item1 = dictOne, dictionaries,Item2 = dictTwo
dictThree = dictionaries.Item1;

我不明白当您说您想分配项目"时，如果您只是想获得对字典的引用或复制它.如果要复制，请使用

I don't understand when you say that you want to "assign items" if you just want to get a reference to the dictionary or make a copy of it. If you want to make a copy, use

dictFour = new Dictionary<string, string>(dictionaries.Item2);
