RouteAttributeHelper.CreateMatchingHandlerDelegate Method

Selects the first handler delegate Type declared on attributeType via
RouteHandlerTypeAttribute whose Invoke signature matches method,
then creates a bound delegate of that type. This lets a single route attribute accept more than one
handler signature (for example ActionExecuteHandler or ActionExecuteInvokeHandler),
resolving the concrete delegate from the decorated method at registration time.
public static Delegate CreateMatchingHandlerDelegate(Microsoft.Agents.Builder.App.AgentApplication app, System.Reflection.MethodInfo method, Type attributeType);static member CreateMatchingHandlerDelegate : Microsoft.Agents.Builder.App.AgentApplication * System.Reflection.MethodInfo * Type -> DelegatePublic Shared Function CreateMatchingHandlerDelegate (app As AgentApplication, method As MethodInfo, attributeType As Type) As DelegateParameters
- app
- AgentApplication
The agent application to bind the delegate to for instance methods.
- method
- MethodInfo
The decorated method to wrap as a delegate.
Returns
A delegate of the matching declared handler type, bound to app for instance methods.
Remarks
Open/unbound generic declared handler types (for example typeof(FetchHandler<>)) are skipped, matching the analyzer behavior; use InvokeGenericWithHandler(AgentApplication, MethodInfo, Type, Int32, Object) for those. When no declared handler matches, an exception is thrown — though the MAA002 analyzer normally surfaces the mismatch at compile time before this code runs.
