Fields

Always Always Always Always Always 0

Always returns the specified container. Creates the container if it does not exist.

Existing Existing Existing Existing Existing 1

Returns the specified container only if it already exists. Raises an exception of type System.Exception if the specified container does not exist.

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.
