Question

所以我有一个复杂的字典：

Dictionary<string, Dictionary< string, HashSet< string >>>

如何打印其键和值？

Answer 1

//example
using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        var dic = new Dictionary<string, Dictionary<string,HashSet<string>>>
        {
            {"k", new Dictionary<string,HashSet<string>>
                {
                    {"k1", new HashSet<string>{"a","b","c"}}
                }
            },
            {"k3", new Dictionary<string,HashSet<string>>
                {
                    {"k4", new HashSet<string>{"1","2","3"}}
                }
            }

        };

        foreach(var p in dic)
        {
            Console.Write(p.Key + " -- ");
            foreach(var p1 in p.Value)
            {
                Console.Write(p1.Key + " -- ");
                foreach(var str in p1.Value)
                {
                    Console.Write(str + " ");
                }
            }
            Console.WriteLine();
        }
    } 
}
output: k -- k1 -- a b c
        k3 -- k4 -- 1 2 3

Answer 2

要将所有值都放入字符串中，您可以使用此

Dictionary<string,string> dictionary;
//[...]

string output = "";
foreach(string key in dictionary.Keys)
{
    output += "\nKey: \""+key+"\" Value: \""+dictionary[key]+"\"";
}
MessageBox.Show(output);

我想你想调整格式，但这应该会有所帮助。

Answer 3

如果您的字典是这样的：

Dictionary<string, Dictionary<string, HashSet<string>>> myDic = new Dictionary<string, Dictionary<string, HashSet<string>>>();

然后你可以做这样的事情将所有结果都变成一个字符串，用新行分隔。

StringBuilder result = new StringBuilder();

foreach (KeyValuePair<string, Dictionary<string, HashSet<string>>> outerDictionaries in myDic)
{
    foreach (KeyValuePair<string, HashSet<string>> innerDictionaries in outerDictionaries)
    {
        result.AppendLine(string.Format("OuterDictionaryKey: {0}, InnerDictionaryKey: {1}, InnerDictionaryValue: {2}", outerDictionaries.Key, innerDictionaries.Key, innerDictionaries.Value));
    }
}

如何打印这本字典？
