LogicalMethodInfo::Invoke Method
Invokes 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^>^ Invoke( Object^ target, array<Object^>^ values )
Parameters
- target
- Type: System::Object
The instance of the Object to invoke the method.
- values
- Type: array<System::Object>
An argument list for the invoked method. This is an array of objects with the same number, order, and type as the parameters of the method. If the method does not require any parameters, the values parameter should be nullptr.
Return Value
Type: array<System::Object>An array of type Object representing the return value and out parameters of the invoked method.
| Exception | Condition |
|---|---|
| TargetException | The target parameter is nullptr. |
| ArgumentException | The number, type, and order of parameters in the values parameter do not match the signature of the invoked method. |
| MemberAccessException | The caller does not have permission to invoke the method. |
| TargetInvocationException | The invoked method throws an exception. |
