Examples

Call the ApplicationDataContainer.CreateContainer | createContainer method to create a settings container or to return an existing container.

This example creates a settings container named exampleContainer and adds a setting named exampleSetting. The Always | always value from the ApplicationDataCreateDisposition enumeration indicates that the container should be created if it does not already exist.

Use the ApplicationDataContainer.Values | values property to access the exampleSetting setting in the exampleContainer container.

Call the ApplicationDataContainer.DeleteContainer | deleteContainer method to delete the exampleContainer settings container when you have finished with it.

var applicationData = Windows.Storage.ApplicationData.current;

var localSettings = applicationData.localSettings;

// Create a setting in a container

var container = localSettings.createContainer("exampleContainer",

if (localSettings.containers.hasKey("exampleContainer"))
{
    localSettings.containers.lookup("exampleContainer").values["exampleSetting"] = "Hello Windows";
}

// Read data from a setting in a container

var hasContainer = localSettings.containers.hasKey("exampleContainer");
