AppDomain.BaseDirectory Property

Gets the base directory that the assembly resolver uses to probe for assemblies.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Public ReadOnly Property BaseDirectory As String

Property Value

Type: System.String
The base directory that the assembly resolver uses to probe for assemblies.




The operation is attempted on an unloaded application domain.

This property corresponds to the AppDomainSetup.ApplicationBase property. It can also be retrieved using the GetData method with the string "APPBASE".

The following code example creates a new application domain, specifying a base directory to use when searching for assemblies to load into the domain. The example then uses the BaseDirectory property to obtain the base directory path, for display to the console.

Imports System
Imports System.Reflection
Imports System.Security.Policy
 'for evidence object 

Class ADSetup

   Public Shared Sub Main()
      ' Create the application domain setup information. 
      Dim domaininfo As New AppDomainSetup()
      domaininfo.ConfigurationFile = System.Environment.CurrentDirectory + "ADSetup.exe.config"
      domaininfo.ApplicationBase = System.Environment.CurrentDirectory

      'Create evidence for the new appdomain from evidence of the current application domain. 
      Dim adevidence As Evidence = AppDomain.CurrentDomain.Evidence

      ' Create appdomain. 
      Dim domain As AppDomain = AppDomain.CreateDomain("MyDomain", adevidence, domaininfo)

      ' Write out the application domain information.
      Console.WriteLine(("Host domain: " + AppDomain.CurrentDomain.FriendlyName))
      Console.WriteLine(("child domain: " + domain.FriendlyName))
      Console.WriteLine(("Configuration file is: " + domain.SetupInformation.ConfigurationFile))
      Console.WriteLine(("Application Base Directory is: " + domain.BaseDirectory))

   End Sub  
End Class
