Application.UserAppDataPath Property

Gets the path for the application data of a user.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

static member UserAppDataPath : string with get

Property Value

Type: System.String
The path for the application data of a user.

If a path does not exist, one is created in the following format:

Base Path\CompanyName\ProductName\ProductVersion

Data stored in this path is part of user profile that is enabled for roaming. A roaming user works on more than one computer in a network. The user profile for a roaming user is kept on a server on the network and is loaded onto a system when the user logs on. For a user profile to be considered for roaming, the operating system must support roaming profiles and it must be enabled.

A typical base path is C:\Documents and Settings\username\Application Data. This path will be different, however, if the Windows Forms application is deployed by using ClickOnce. ClickOnce creates its own application data directory that is isolated from all other applications. For more information, see Accessing Local and Remote Data in ClickOnce Applications.

The following code example displays two forms and exits the application when both forms are closed. When the application starts and exits, the position of each form is remembered. This example demonstrates using the UserAppDataPath property to store application data for the user.

The class MyApplicationContext inherits from ApplicationContext and keeps track when each form is closed, and exits the current thread when they both are. The class stores the positions of each form for the user. The form position data is stored in a file titled Appdata.txt that is created in the location determined by UserAppDataPath. The Main method calls Application.Run(context) to start the application given the ApplicationContext.

This code is an excerpt from the example shown in the ApplicationContext class overview. Some code is not shown for the purpose of brevity. See ApplicationContext for the whole code listing.
