MethodExecutionArgs.ReturnValue Property

public Object ReturnValue { get; set; }

Property Value

You can modify the return value only when the join point is located after a method execution (OnSuccess(MethodExecutionArgs), OnException(MethodExecutionArgs) or OnExit(MethodExecutionArgs), or in case you force the method to exit using the FlowBehavior property.

Note
As a result of weaving optimizations, value of this property may be seen null in a debugger. If you need to inspect the value in runtime, consider disabling aspect optimizations in the debug build configuration.
