从文件读取和写入嵌套字典？

Question

我是Windows手机的新手。我成功地编写并从文件中读取字典。但是我从文件中读出了嵌套的词典。

1. Main_dictionary
   1. 登录（键），字典（值）`
   2. 验证（Key），字典（Value）
2. Main_dictionary

我需要将Common字典下的这些值写入文件，还需要从同一个文件中读取。任何帮助。

先谢谢

Answer 1

您可以按照XmlSerializer中的说明使用How to XML-serialize a dictionary。它引用了http://huseyint.com/2007/12/xml-serializable-generic-dictionary-tipi/中的示例代码（不是英文，但代码很有用）。

我得到了解决方案...........

public Dictionary FileRead（string Key）         {             字典＆gt; FileResponse = new Dictionary＆gt;（）;            Dictionary ReturnDictionary = new Dictionary（）;            尝试            {                 使用（IsolatedStorageFile isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication（））                {                    using（IsolatedStorageFileStream fileReader = new IsolatedStorageFileStream（DisplayMessage.Storage_Directory，FileMode.Open，FileAccess.ReadWrite，isolatedStorage））                     {                         DataContractSerializer datacontract = new DataContractSerializer（typeof（Dictionary＆gt;））;                         FileResponse =（Dictionary＆gt;）datacontract.ReadObject（fileReader）;                         ReturnDictionary = FileResponse [Key];                     }                 }            }            catch（Exception ex）             {             }             return（ReturnDictionary）;         }

   public void FileWrite(string Key,Dictionary<string, string> FiletoStore)
    {
       try
        {
           using (IsolatedStorageFile isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
            {
                Dictionary<string, Dictionary<string, string>> StoredDictionary = new Dictionary<string, Dictionary<string, string>>();
                if (!isolatedStorage.FileExists(DisplayMessage.Storage_Directory))
               {
                   using (IsolatedStorageFileStream IsolatedfileStream = new IsolatedStorageFileStream(DisplayMessage.Storage_Directory, FileMode.OpenOrCreate, isolatedStorage))
                   {
                        DataContractSerializer datacontract = new DataContractSerializer(typeof(Dictionary<string, Dictionary<string, string>>));
                       StoredDictionary.Add(Key, FiletoStore);
                       datacontract.WriteObject(IsolatedfileStream, StoredDictionary);
                      IsolatedfileStream.Close();
                    }
                }
               else
                {
                    using (IsolatedStorageFileStream IsolatedfileStream = new IsolatedStorageFileStream(DisplayMessage.Storage_Directory, FileMode.Open, isolatedStorage))
                    {
                        DataContractSerializer datacontract = new DataContractSerializer(typeof(Dictionary<string, Dictionary<string, string>>));
                       StoredDictionary.Add(Key, FiletoStore);
                       datacontract.WriteObject(IsolatedfileStream, StoredDictionary);
                      IsolatedfileStream.Close();
                   }
              }
           }
       }
       catch (Exception ex)
      {
       }
    }
