How to cache data at WPF after the application closed?

[michalush85]

Hi, I have WPF app and I need to save the data(Hashtable) into the Cache for one day,also if the app was closed. I try to use ObjectCache but it cleaned in every running. May anyone have a solution, Thanks a lot.

What Cache? If you are trying to save data, you may consider writing out as XML, or saving it to a database or serializing it to file. The choice depends on your application needs and architecture.

Hi, Thanks for fast reply :) . I have an Hashtable that contains objects. And I want to save it not matter what. I will glad if you can explain to me what is the better way to do it(XML or file)? Thanks again.

If the objects are all serializable, then it's a simple matter to serialize them to file using something like the XmlSerializer.

Hi, Thanks again. 1)Can I serialize only the Hashtable? Or I need to serialize every object one by one? 2)I have one Hashtable that its objects don't serializable, Is there any way to cache it? Thanks a lot.

Serializing the hash table should serialize the component objects. Remember that they need to be serializable objects in their own right for this to work.

Thanks, I have linq to sql objects and I found that I can serialize the sql by putting this: < Database ... Serialization="Unidirectional > on the dbml file. How can I serialize Hashtable that contain objects like that? Thanks a lot.

Why would you want to? This indicates that the data is already saved to the database - meaning you don't need to save it to a different storage medium.

I have sql query and I want to save every running the row that selected from each table. I found solution for that :D. I mark the dmbl as serializable with

<Database... Serialization="Unidirectional">

and than use NetDataContractSerializer object to serialize\deserialize. Now, I have another problem, I want to save also the search criterions, every search I save the controls with the search criterions in hashtable, and I want to save it also at xml but the controls are not serializable(I use wpf and telerik controls). Is thare any way to do it? Thanks again.
