LogicalMethodInfo::EndInvoke Method
Ends an asynchronous invocation of the method represented by the current LogicalMethodInfo.
Assembly: System.Web.Services (in System.Web.Services.dll)
[PermissionSetAttribute(SecurityAction::LinkDemand, Name = L"FullTrust")] public: array<Object^>^ EndInvoke( Object^ target, IAsyncResult^ asyncResult )
Parameters
- target
- Type: System::Object
The instance of the Object on which to invoke the method.
- asyncResult
- Type: System::IAsyncResult
The IAsyncResult returned from BeginInvoke.
Return Value
Type: array<System::Object>An array of objects containing the return value and any by-reference or out parameters of the derived class method.
| Exception | Condition |
|---|---|
| TargetException | The target parameter is nullptr. |
| MemberAccessException | The caller does not have permission to invoke the method. |
| TargetInvocationException | The invoked method throws an exception. |
