AppDomain.BaseDirectory Property

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

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

public string BaseDirectory { get; }

Property Value

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

Implements

_AppDomain.BaseDirectory

ExceptionCondition
AppDomainUnloadedException

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 System;
using System.Reflection;
using System.Security.Policy;  

class ADSetup
{
    public static void Main()
    {
        // Create application domain setup information
        AppDomainSetup domaininfo = 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
        Evidence adevidence = AppDomain.CurrentDomain.Evidence;

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

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

        AppDomain.Unload(domain);
    }
}
