Xamarin Essentials Preferences

Xamarin.Essentials provides a way to store key-value data in the specific platform preferences.

The preference API is accessible from any shared code including shared projects, PCLs, and .NET Standard Libraries.

Syntax

Preferences.Get(string key, T defaultValue);
Preferences.Set(string key, T value);
Preferences.ContainsKey(string key);
Preferences.Remove(string key);
Preferences.Clear();

Example

public void SaveToPreferences()
{
    Preferences.Set("key", "value");
}

public string LoadFromPreferences()
{
   string preference = "";
   if (Preferences.ContainsKey("key"))
      preference = Preferences.Get("key", "");
   return preference;
}

Output

We can store and retrieve data from the application preferences.

Xamarin.Essentials Preferences provides a simple programming model for storing and retrieving preferences.

The API is available from any shared code, including shared projects and .NET Standard Libraries.

You can save and retrieve all the primitives data types (Boolean, Float, Double, Int32, Int64, and String) safely.

Other types can be handled using serialization.

It is often used to store user preferences, session-specific data that must be preserved between application launches, or other key-value related data.
