AppDomain.CreateDomain Method (String, Evidence, String, String, Boolean, AppDomainInitializer, String[])


Creates a new application domain with the given name, using evidence, application base path, relative search path, and a parameter that specifies whether a shadow copy of an assembly is to be loaded into the application domain. Specifies a callback method that is invoked when the application domain is initialized, and an array of string arguments to pass the callback method.

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

public static AppDomain CreateDomain(
	string friendlyName,
	Evidence securityInfo,
	string appBasePath,
	string appRelativeSearchPath,
	bool shadowCopyFiles,
	AppDomainInitializer adInit,
	string[] adInitArgs


Type: System.String

The friendly name of the domain. This friendly name can be displayed in user interfaces to identify the domain. For more information, see FriendlyName.

Type: System.Security.Policy.Evidence

Evidence that establishes the identity of the code that runs in the application domain. Pass null to use the evidence of the current application domain.

Type: System.String

The base directory that the assembly resolver uses to probe for assemblies. For more information, see BaseDirectory.

Type: System.String

The path relative to the base directory where the assembly resolver should probe for private assemblies. For more information, see RelativeSearchPath.

Type: System.Boolean

true to load a shadow copy of an assembly into the application domain.

Type: System.AppDomainInitializer

An AppDomainInitializer delegate that represents a callback method to invoke when the new AppDomain object is initialized.

Type: System.String[]

An array of string arguments to be passed to the callback represented by adInit, when the new AppDomain object is initialized.

Return Value

Type: System.AppDomain

The newly created application domain.

Exception Condition

friendlyName is null.

The method represented by adInit is executed in the context of the newly created application domain.

If securityInfo is not supplied, the evidence from the current application domain is used.

For more information about shadow copying, see ShadowCopyFilesand Shadow Copying Assemblies.


Do not use this method overload to create sandboxed application domains. Beginning with the .NET Framework 4, the evidence that is supplied for securityInfo no longer affects the grant set of the application domain. Use the CreateDomain(String, Evidence, AppDomainSetup, PermissionSet, StrongName[]) method overload to create sandboxed application domains.
