ResolveEventHandler Delegate

Represents a method that handles the AppDomain.TypeResolve, AppDomain.ResourceResolve, or AssemblyResolve event of an AppDomain.

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

[SerializableAttribute]
[ComVisibleAttribute(true)]
public delegate Assembly ResolveEventHandler(
	Object sender,
	ResolveEventArgs args
)

Parameters

sender
Type: System.Object

The source of the event.

args
Type: System.ResolveEventArgs

The event data.

Return Value

Type: System.Reflection.Assembly
The assembly that resolves the type, assembly, or resource; or null if the assembly cannot be resolved.

If the runtime class loader cannot resolve a reference to an assembly, type, or resource, the corresponding events are raised to give the callback a chance to tell the runtime which assembly the referenced assembly, type, or resource is in. It is the responsibility of the ResolveEventHandler to return the assembly that resolves the type, assembly, or resource, or to return null if the assembly is not recognized. For more information, see Resolving Assembly Loads and the AppDomain.ResourceResolve, AppDomain.AssemblyResolve, and AppDomain.ReflectionOnlyAssemblyResolve events.

Important noteImportant

Beginning with the .NET Framework 4, the System.ResolveEventHandler event is raised for all assemblies, including resource assemblies. In earlier versions, the event was not raised for resource assemblies. If the operating system is localized, the handler might be called multiple times: once for each culture in the fallback chain.

Every derived class of Delegate and MulticastDelegate has a constructor and an Invoke method. See the C++ code example in the description for the Delegate class.
