C# 如何使用字典引用其他字典?

Question

根据我在其他地方读到的内容，一般建议是使用字典来动态访问变量/对象和其他字典......但是，对于最后一种情况，我似乎缺少一些简单的东西，因为我看不到如何使其工作。基本上我有多个数据字典，我希望使用变量中的值指向相应的字典并读取其数据：

//----------------------------------------------------------------------------------------
// reference dictionary - pass LangID string to reference appropriate dictionary
public static Dictionary<string, dynamic> myDictionaries = new Dictionary<string, dynamic>()
{
{ "EN", "EN_Dictionary" },
{ "FR", "FR_Dictionary" },
{ "DE", "DE_Dictionary" }
};
//----------------------------------------------------------------------------------------
public static Dictionary<string, string> EN_Dictionary = new Dictionary<string, string>()
// EN language dictionary
{
{ "str1", "Some text in EN" },
{ "str2", "Some text in EN" },
{ "str3", "Some text in EN" }
};
//----------------------------------------------------------------------------------------
public static Dictionary<string, string> FR_Dictionary = new Dictionary<string, string>()
// FR language dictionary
{
{ "str1", "Some text in FR" },
{ "str2", "Some text in FR" },
{ "str3", "Some text in FR" }
};
//----------------------------------------------------------------------------------------
public static Dictionary<string, string> DE_Dictionary = new Dictionary<string, string>()
// DE language dictionary
{
{ "str1", "Some text in DE" },
{ "str2", "Some text in DE" },
{ "str3", "Some text in DE" }
};
//----------------------------------------------------------------------------------------
LangID = "DE";

//...但现在我该怎么办???

Answer 1

你在问如何访问字典吗？ 具体如下：

var text = myDictionaries["EN"]["str1"];

你需要像这样定义你的字典：

public static Dictionary<string, string> EN_Dictionary = ...etc;
public static Dictionary<string, string> FR_Dictionary  = ...etc;
public static Dictionary<string, string> DE_Dictionary = ...etc;
public static Dictionary<string, Dictionary<string, string>> myDictionaries 
= new Dictionary<string, Dictionary<string, string>>()
{
{ "EN", EN_Dictionary },
{ "FR", FR_Dictionary },
{ "DE", DE_Dictionary }
};

Answer 2

我将动态更改为语言词典的实际定义，然后添加了变量而不是字符串。

// reference dictionary - pass LangID string to reference appropriate dictionary
public static Dictionary<string, Dictionary<string, string>> myDictionaries = new Dictionary<string, Dictionary<string, string>>()
{
{ "EN", EN_Dictionary },
{ "FR", FR_Dictionary },
{ "DE", DE_Dictionary }
};
public static Dictionary<string, string> EN_Dictionary = new Dictionary<string, string>()
{
{ "str1", "Some text in EN" },
{ "str2", "Some text in EN" },
{ "str3", "Some text in EN" }
};
public static Dictionary<string, string> FR_Dictionary = new Dictionary<string, string>()
// FR language dictionary
{
{ "str1", "Some text in FR" },
{ "str2", "Some text in FR" },
{ "str3", "Some text in FR" }
};
public static Dictionary<string, string> DE_Dictionary = new Dictionary<string, string>()
// DE language dictionary
{
{ "str1", "Some text in DE" },
{ "str2", "Some text in DE" },
{ "str3", "Some text in DE" }
};

要使用参考词典...

private void button1_Click(object sender, EventArgs e)
{
string LangID = "DE";
Dictionary<string, string> GermanDictionary = myDictionaries[LangID];
string PhraseID = "str2";
string GermanPhrase = GermanDictionary[PhraseID];
}

Answer 3

您可以使用字典字典。例：

Dictionary<String, Dictionary<String, String>>

密钥和数据类型可能会根据您的需要而有所不同。
