将字典写入磁盘

问题描述

我的应用需要在会话之间将数据从其Dictionary对象写入磁盘。 WriteAllBytes和ReadAllBytes将是最快的方式，但我不知道如何将字典转换为字节。



有人可以提出解决方案吗？ VB.net用于我的应用程序，但也欢迎C＃响应。



我尝试过：



直播，投射功能，搜索www

My app needs to write data from its Dictionary objects to disk between sessions. WriteAllBytes and ReadAllBytes would be the fastest way, but I do not know how to convert the dictionaries to bytes.

Can someone suggest a solution please? VB.net is used for my app but C# responses will be welcome too.

What I have tried:

directcast, cast functions, searching the www

推荐答案

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

class Test
{
   // A dictionary to save/load
   private Dictionary<int, string> _dictionary = new Dictionary<int, string>();

   // A method to save the dictionary to disk
   void Save(string path) {
      using (FileStream fs = new FileStream(path, FileMode.Create)) {
         BinaryFormatter formatter = new BinaryFormatter();
         formatter.Serialize(fs, _dictionary);
      }
   }

   // A method to load the dictionary from the disk
   void Load(string path) {
      using (FileStream fs = new FileStream(path, FileMode.Open)) {
         BinaryFormatter formatter = new BinaryFormatter();
         _dictionary = (Dictionary<int, string>)formatter.Deserialize(fs);
      }
   }
}

当然，您可能希望在不错的try..catch块中添加这些以便错误可以被处理。但是你有一般原则。



亲切。

Of course, you may want to add these in nice try..catch blocks so that errors can be handled. But you have the general principle.

Kindly.
