在WP7的隔离存储中存储类对象

Question

How can I store object of a class in WP7 Isolated Storage? I want to retrieve it and edit it whenever required.

Answer 1

You need to serialize your data to save it, then deserialize it to load it. You can find a complete worked example in this article .

For example, mark the class and properties as follows:

[DataContract] 
public class Employee  
{  
     [DataMember] 
     public int EmployeeNumber { get; set; }  
     [DataMember] 
     public string Name { get; set; }  
     [DataMember] 
     public string Department { get; set; }  
}

Construct a serializer:

DataContractSerializer mySerializer = new DataContractSerializer(typeof(Employee)); 

Then load / save via ReadObject / WriteObject .

U can use xml serialisation

    public static void Serialize<T>(T obj, string fileName)
    {   
     try
      {
        var store = IsolatedStorageFile.GetUserStoreForApplication();
        IsolatedStorageFileStream stream = store.OpenFile(fileName, FileMode.Create);

        XmlSerializer serializer = new XmlSerializer(typeof(T));

        using (XmlWriter xmlWriter = XmlWriter.Create(stream, writerSettings))
        {
            serializer.Serialize(xmlWriter, obj);
        }

    stream.Close();
   }
   catch (Exception ex)
   {
      throw ex;
   }
  }


    public static T DeSerialize<T>(string fileName)
    {
      try
      {
         var store = IsolatedStorageFile.GetUserStoreForApplication();
         IsolatedStorageFileStream stream = store.OpenFile(fileName, FileMode.Open);

         XmlSerializer serializer = new XmlSerializer(typeof(T));
         return (T)serializer.Deserialize(stream);
      }
      catch (Exception ex)
      {
        throw ex;
      }
    }
