AppDomain.RelativeSearchPath Property

Gets the path under the base directory where the assembly resolver should probe for private assemblies.

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

'Declaration
Public ReadOnly Property RelativeSearchPath As String

Property Value

Type: System.String
The path under the base directory where the assembly resolver should probe for private assemblies.

Implements

_AppDomain.RelativeSearchPath

ExceptionCondition
AppDomainUnloadedException

The operation is attempted on an unloaded application domain.

Private assemblies are deployed in the same directory structure as the application. If the path specified by the RelativeSearchPath property is not under AppDomainSetup.ApplicationBase, it is ignored.

This property returns the value set using AppDomainSetup.PrivateBinPath.

The following example creates a new application domain that uses shadow copying. The example uses the RelativeSearchPath property to retrieve the base directory for private assemblies, and then displays it to the console.

To compile and run this example, you must insert the valid display names of assemblies where indicated in the code.
