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)

public string RelativeSearchPath { get; }

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.

using System;
using System.Security.Policy;  //for evidence object 
namespace AppDomainSnippets
{
	class ADProperties
	{
		static void Main(string[] args)
		{

			AppDomainSetup setup = new AppDomainSetup();
			// Shadow copying will not work unless the application has a name.
			setup.ApplicationName = "MyApplication";

			//Create evidence for the new application domain from evidence of 
			// current application domain.
			Evidence adevidence = AppDomain.CurrentDomain.Evidence;
			
			// Create a new application domain.
			AppDomain domain = AppDomain.CreateDomain("MyDomain", adevidence, setup);
			
			// MyAssembly.dll is located in the Assemblies subdirectory.
			domain.AppendPrivatePath("Assemblies");
			// MyOtherAssembly.dll and MyThirdAssembly.dll are located in the 
			// MoreAssemblies subdirectory.
			domain.AppendPrivatePath("MoreAssemblies");
			// Display the relative search path.
			Console.WriteLine("RelativeSearchPath: " + domain.RelativeSearchPath);
			// Because Load returns an Assembly object, the assemblies must be 
			// loaded into the current domain as well. This will fail unless the 
			// current domain also has these directories in its search path.
			AppDomain.CurrentDomain.AppendPrivatePath("Assemblies");
			AppDomain.CurrentDomain.AppendPrivatePath("MoreAssemblies");
			
			// Save shadow copies to C:\Cache
			domain.SetCachePath("C:\\Cache");
			// Shadow copy only the assemblies in the Assemblies directory.
			domain.SetShadowCopyPath(domain.BaseDirectory + "Assemblies");
			// Turn shadow copying on.
			domain.SetShadowCopyFiles();
			Console.WriteLine("ShadowCopyFiles turned on: " + domain.ShadowCopyFiles);

			// This will be copied. 
			// You must supply a valid fully qualified assembly name here. 
			domain.Load("Assembly1 text name, Version, Culture, PublicKeyToken");
			// This will not be copied. 
			// You must supply a valid fully qualified assembly name here. 
			domain.Load("Assembly2 text name, Version, Culture, PublicKeyToken");
			
			// When the shadow copy path is cleared, the CLR will make shadow copies 
			// of all private assemblies.
			domain.ClearShadowCopyPath();
			// MoreAssemblies\MyThirdAssembly.dll should be shadow copied this time. 
			// You must supply a valid fully qualified assembly name here.
			domain.Load("Assembly3 text name, Version, Culture, PublicKeyToken");
			
			// Unload the domain.
			AppDomain.Unload(domain);
