Private m_oStartSize Ī manager class for saving and loading: public class CConfigMng The configuration dataobject is strongly typed and easy to use: Here is an example to store the position and size of a form. rules that can cancel applying/persisting data for a propertyĪ simple way is to use a configuration data object, save it as an XML file with the name of the application in the local Folder and on startup read it back. file, database, online, isolated storage, registry) when data is persisted and applied globally or for each tracked object It's highly configurable, and you can configure: When the target objects are created by an IoC container, you can so that it applies tracking automatically to all objects it resolves, so that all you need to do to make a property persistent is slap a attribute on it.

With a settings files you need to mention each property five times: once when you explicitly create the property and an additional four times in the code that copies the values back and forth. settings files: There's considerably less code, and it's a lot less error-prone since you only need to mention each property once. AddProperties(nameof(Height), nameof(Width), nameof(Left), nameof(Top), nameof(WindowState))

Here's how you'd use it to keep track of a window's size and location: public MainWindow() Here is an old The Code Project article I wrote about it. It's a tiny library, but a big improvement (IMHO) over. I wanted to share a library I've built for this. Tar.GetType().GetProperty(obj.Key).SetValue(tar, obj.Value, null) String paramList = targ.Split(new char // If fails - just don't use preferences. Internal static void Save(object src, string targ, string fileName) It is just a sample, not suggestive of best practices. Properties may be recovered using: AppSettings.Load(myobject, 'myFile.jsn') Such as: AppSettings.Save(myobject, 'Prop1,Prop2', 'myFile.jsn') The following sample allows storage of an objects named properties to a file in isolated storage. I've used them all, as the technology has progressed, but my favourite is based on Threed's system combined with Isolated Storage. The registry/configurationSettings/XML argument still seems very active. T = (new JavaScriptSerializer()).Deserialize(File.ReadAllText(fileName)) Public static T Load(string fileName = DEFAULT_FILENAME)

Public static void Save(T pSettings, string fileName = DEFAULT_FILENAME)įile.WriteAllText(fileName, (new JavaScriptSerializer()).Serialize(pSettings)) Public void Save(string fileName = DEFAULT_FILENAME)įile.WriteAllText(fileName, (new JavaScriptSerializer()).Serialize(this)) Private const string DEFAULT_FILENAME = 'settings.json' If you are planning on saving to a file within the same directory as your executable, here's a nice solution that uses the JSON format: using System Ĭonsole.WriteLine('Current value of 'myInteger': ' + settings.myInteger) Ĭonsole.WriteLine('Incrementing 'myInteger'.')
