AppDomain.AssemblyLoad Event
Occurs when an assembly is loaded.
[Visual Basic] Public Overridable Event AssemblyLoad As AssemblyLoadEventHandler [C#] public virtual event AssemblyLoadEventHandler AssemblyLoad; [C++] public: virtual __event AssemblyLoadEventHandler* AssemblyLoad;
[JScript] In JScript, you can handle the events defined by a class, but you cannot define your own.
Event Data
The event handler receives an argument of type AssemblyLoadEventArgs containing data related to this event. The following AssemblyLoadEventArgs property provides information specific to this event.
| Property | Description |
|---|---|
| LoadedAssembly | Gets an Assembly that represents the currently loaded assembly. |
Remarks
The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.
To register an event handler for this event, you must have the permissions described in the Permissions section. If you do not have the appropriate permissions, a SecurityException occurs.
For more information about handling events, see Consuming Events.
Example
[Visual Basic, C#, C++] The following sample demonstrates the AssemblyLoad event.
[Visual Basic, C#, C++] For this code example to run, you must provide the fully qualified assembly name. For information about how to obtain the fully qualified assembly name, see Assembly Names.
