System.AppDomain class

Processes are independent of memory and resources, but the AppDomain is only a logical abstraction. A process can exist in more than one AppDomain. Data between the AppDomain is independent of each other. A thread can shuttle multiple AppDomain.

First, the attribute

ActivationContext gets the activation context for the current application domain.
ApplicationIdentity gets the application identity in the application domain.
ApplicationTrust Gets the information that describes the permissions granted to the application and whether the application has a trust level that allows it to run.
BaseDirectory gets the base directory, which is used by the Assembly resolver to probe assemblies.
CurrentDomain gets the current application domain of the Thread.
Domainmanager Gets the domain manager provided by the host when the application domain is initialized.
Dynamicdirectory Gets the directory that is used by the Assembly resolver to probe for dynamically created assemblies.
Evidence gets the Evidence associated with the application domain.
FriendlyName gets the friendly name of this application domain.
Id gets an integer that uniquely identifies the application domain in the process.

Monitoringisenabled Gets or sets a value that indicates whether CPU and memory monitoring of the application domain is enabled for the current process. Once monitoring is enabled for a process, it cannot be disabled.
Monitoringsurvivedmemorysize Gets the number of bytes that are known to be referenced by the current application domain after the last fully blocked collection.
Monitoringsurvivedprocessmemorysize gets the total number of bytes that were retained after the last full block collection of all application domains in the process.
Monitoringtotalallocatedmemorysize gets the total size, in bytes, of all memory allocations that have been made by the application domain since the application domain was created, without deducting the reclaimed memory.
Monitoringtotalprocessortime gets the total processor time that is used by threads that have been executing in the current application domain since the process started.
PermissionSet gets the permission set for the sandbox application domain.
Relativesearchpath gets the path under the base directory in which the Assembly resolver should probe the private assembly.
Setupinformation Gets the application domain configuration information for this instance.
Shadowcopyfiles gets an indication whether the application domain is configured as an image copy file.

Second, the method

Name Description
ApplyPolicy returns the assembly display name after the policy is applied.
Createcominstancefrom (String, String) creates a new instance of the specified COM type. parameter specifies the name of the file that contains the assembly that contains the type and type name.
CreateDomain (String) creates a new application domain with the specified name.
CreateInstance (String, String) creates a new instance of the specified type defined in the specified assembly.
Createinstanceandunwrap (String, String) creates a new instance of the specified type. Formal parameters specify the assembly that defines the type and the name of the type.
CreateInstanceFrom (String, String) creates a new instance of the specified type defined in the specified assembly file.
Createobjref creates an object that contains all the relevant information that is required to generate a proxy for communicating with a remote object. (inherited from MarshalByRefObject.) ）
DefineDynamicAssembly (AssemblyName, assemblybuilderaccess) defines the dynamic assembly with the specified name and access pattern.
DoCallback executes code in another application domain that is identified by the specified delegate.
ExecuteAssembly (String) executes the assembly contained in the specified file.
ExecuteAssemblyByName (String) executes the assembly given its display name.
Getassemblies Gets the assembly that has been loaded into the execution context of this application domain.
GetData gets the value stored in the current application domain for the specified name.
Getlifetimeservice retrieves the current lifetime service object that controls the lifetime policy of this instance. (inherited from MarshalByRefObject.) ）
InitializeLifetimeService gives the AppDomain an infinite lifetime by preventing the creation of leases. (Rewrite MarshalByRefObject.InitializeLifetimeService (). ）

SetData (String, Object) assigns the specified value to the specified application domain property.
SetData (String, Object, IPermission) assigns the specified value to the specified application domain property, which requires the caller to have the specified permission when retrieving the property.
SETPRINCIPALPOLICY specifies how the user and identity object should be attached to the thread when it executes in this application domain if the thread tries to bind to the user.
