AppDomain::BaseDirectory Property

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

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

virtual property String^ BaseDirectory {
	String^ get () sealed;

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.

using namespace System;
using namespace System::Reflection;
using namespace System::Security::Policy;

//for evidence Object
int main()

   // Create application domain setup information
   AppDomainSetup^ domaininfo = gcnew AppDomainSetup;
   domaininfo->ConfigurationFile = String::Format( "{0}ADSetup.exe.config", System::Environment::CurrentDirectory );
   domaininfo->ApplicationBase = String::Format( "{0}", System::Environment::CurrentDirectory );

   //Create evidence for the new appdomain from evidence of the current application domain
   Evidence^ adevidence = AppDomain::CurrentDomain->Evidence;

   // Create appdomain
   AppDomain^ domain = AppDomain::CreateDomain( "MyDomain", adevidence, domaininfo );

   // Write out application domain information
   Console::WriteLine( "Host domain: {0}", AppDomain::CurrentDomain->FriendlyName );
   Console::WriteLine( "child domain: {0}", domain->FriendlyName );
   Console::WriteLine( "Configuration file is: {0}", domain->SetupInformation->ConfigurationFile );
   Console::WriteLine( "Application Base Directory is: {0}", domain->BaseDirectory );
   AppDomain::Unload( domain );
