ToolboxService.GetToolboxItems Method (AssemblyName)
Assembly: System.Drawing.Design (in System.Drawing.Design.dll)
- Type: System.Reflection.AssemblyName
An assembly name from which to load an assembly.
Return ValueType: System.Collections.ICollection
A collection containing all the toolbox items in the assembly represented by the given assembly name.
The GetToolboxItems method scans the assembly for all types that support toolbox items, and return items for those types. To support a toolbox item, a type must have the following characteristics:
Not be abstract.
Not have a ToolboxItemAttribute set to false on its type.
Not contain generic parameters.
Assemblies are locked for the duration of a process, so enumerating various files through GetToolboxItems can cause many assemblies to be loaded. The GetToolboxItems methods that take an assembly name create a separate AppDomain to search assemblies. When you are finished enumerating ToolboxItem objects for a set of assemblies, you can call the UnloadToolboxItems method, which unloads the AppDomain and frees the file references on the loaded assemblies.
Assemblies loaded in this manner are loaded into a separate AppDomain so they can later be unloaded. This only momentarily locks the assembly file.
