AppDomain.CreateDomain Method (String)

Creates a new application domain with the specified name.

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

static AppDomain^ CreateDomain (
	String^ friendlyName
public static AppDomain CreateDomain (
	String friendlyName
public static function CreateDomain (
	friendlyName : String
) : AppDomain
Not applicable.



The friendly name of the domain.

Return Value

The newly created application domain.

Exception typeCondition


friendlyName is a null reference (Nothing in Visual Basic).

The friendlyName parameter is intended to identify the domain in a manner that is meaningful to humans. This string should be suitable for display in user interfaces.

This method overload uses the AppDomainSetup information from the default application domain.

If the current application domain has an empty Evidence, SecurityException is thrown when creating a new application domain. An empty Evidence always results in an empty grant set. For example, a default application domain can have an empty Evidence if it is created from unmanaged code.

The following sample demonstrates, in general, how to create a domain using one of the CreateDomain overloads.

// Set up the AppDomainSetup
AppDomainSetup^ setup = gcnew AppDomainSetup;
setup->ApplicationBase = "(some directory)";
setup->ConfigurationFile = "(some file)";

// Set up the Evidence
Evidence^ baseEvidence = AppDomain::CurrentDomain->Evidence;
Evidence^ evidence = gcnew Evidence( baseEvidence );
evidence->AddAssembly( "(some assembly)" );
evidence->AddHost( "(some host)" );

// Create the AppDomain
AppDomain^ newDomain = AppDomain::CreateDomain( "newDomain", evidence, setup );

// Set up the AppDomainSetup
AppDomainSetup setUp = new AppDomainSetup();
setUp.set_ApplicationBase("(some directory)");
setUp.set_ConfigurationFile("(some file)");
// Set up the Evidence
Evidence baseEvidence = AppDomain.get_CurrentDomain().get_Evidence();
Evidence evidence = new Evidence(baseEvidence);
evidence.AddAssembly("(some assembly)");
evidence.AddHost("(some host)");
// Create the AppDomain      
AppDomain newDomain = AppDomain.CreateDomain("newDomain", evidence, setUp);
