Here are some ways to save data in a WinRT application, the method with the settings in the name is probably what you are looking for! - others just added, - you can also serialize the data if you want. This is working code, but be sure to add error handling, etc. This is a simple demo code :)
As for settings, you can save simple settings as a key and values, and for more complex settings you can use a container. I gave both examples: =)
public class StorageExamples
{
public async Task<string> ReadTextFileAsync(string path)
{
var folder = ApplicationData.Current.LocalFolder;
var file = await folder.GetFileAsync(path);
return await FileIO.ReadTextAsync(file);
}
public async void WriteTotextFileAsync(string fileName, string contents)
{
var folder = ApplicationData.Current.LocalFolder;
var file = await folder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);
await FileIO.WriteTextAsync(file, contents);
}
public void SaveSettings(string key, string contents)
{
ApplicationData.Current.LocalSettings.Values[key] = contents;
}
public string LoadSettings(string key)
{
var settings = ApplicationData.Current.LocalSettings;
return settings.Values[key].ToString();
}
public void SaveSettingsInContainer(string user, string key, string contents)
{
var localSetting = ApplicationData.Current.LocalSettings;
localSetting.CreateContainer(user, ApplicationDataCreateDisposition.Always);
if (localSetting.Containers.ContainsKey(user))
{
localSetting.Containers[user].Values[key] = contents;
}
}
}
