保存可变数据到磁盘 [英] Saving a variable data to disk

问题描述

时可以节约从C＃到磁盘上的变量，以便您能够在您的项目的另一个实例中用到它？

例如，我有3个领域，如下面的示例结构：

 结构MYSTRUCT
{
    byte []的ByteData;
    INT敏;
    双MyDouble;
};
 

我有这样的结构的一个实例，让我们说 MYSTRUCT小号，我将值分配给我的所有领域。 经过这一步，我想以某种方式保存该变量的磁盘，这样我可以在我的程序后使用这些存储的值。

我知道，我可以复制上一个txt文件的价值，但我想保存的变量，因为它是在我的硬盘，这样我可以我的项目的下一个运行期间直接加载到内存中。

是否有可能以某种方式保存在磁盘上，这样我可以我的程序中加载它，因为它是？

解决方案

 公共无效SerializeObject＆LT; T＆GT;（字符串文件名，T OBJ）
   {
      流流= File.open方法（文件名，FileMode.Create）;
      的BinaryFormatter的BinaryFormatter =新的BinaryFormatter（）;
      binaryFormatter.Serialize（流OBJ）;
      stream.Close（）;
   }

   公共牛逼DeSerializeObject＆LT; T＆GT; （字符串文件名）
   {
      牛逼objectToBeDeSerialized;
      流流= File.open方法（文件名，FileMode.Open）;
      的BinaryFormatter的BinaryFormatter =新的BinaryFormatter（）;
      objectToBeDeSerialized =（T）binaryFormatter.Deserialize（流）;
      stream.Close（）;
      返回objectToBeDeSerialized;
   }

[可序列化]
结构MYSTRUCT
{
    byte []的ByteData;
    INT敏;
    双MyDouble;
}
 

不要忘记标记您的对象序列化。

Is it possible to save a variable from C# to disk so that you are able to use it later in another instance of your project?

For example, I have a struct with 3 fields like in the following example :

struct MyStruct
{
    byte[] ByteData;
    int MyInt;
    double MyDouble;
};

I have an instance of this struct, let's say MyStruct S and I assign value to all my fields. After this step, I would like to save this variable somehow in disk so that I could use those stored values later in my program.

I know, that I could copy those value on a .txt file, but I would like to save the variable as it is on my disk so that I could directly load it into memory during the next runtime of my project.

Is it possible to save it somehow on the disk so that I could load it inside my program as it is?

解决方案

public void SerializeObject<T>(string filename, T obj)
   {
      Stream stream = File.Open(filename, FileMode.Create);
      BinaryFormatter binaryFormatter = new BinaryFormatter();
      binaryFormatter.Serialize(stream, obj);
      stream.Close();
   }

   public T DeSerializeObject<T> (string filename)
   {
      T objectToBeDeSerialized;
      Stream stream = File.Open(filename, FileMode.Open);
      BinaryFormatter binaryFormatter = new BinaryFormatter();
      objectToBeDeSerialized= (T)binaryFormatter.Deserialize(stream);
      stream.Close();
      return objectToBeDeSerialized;
   }

[Serializable]
struct MyStruct
{
    byte[] ByteData;
    int MyInt;
    double MyDouble;
}

Do not forget to mark your object as serializable.
