Intercept Properties With Castle Windsor IInterceptor
- by jeffn825
Does anyone have a suggestion on a better way to intercept a properties with Castle DynamicProxy? Specifcally, I need the PropertyInfo that I'm intercepting, but it's not directly on the IInvocation, so what I do is:
public static PropertyInfo GetProperty(this MethodInfo method)
{
bool takesArg = method.GetParameters().Length == 1;
bool hasReturn = method.ReturnType != typeof(void);
if (takesArg == hasReturn) return null;
if (takesArg)
{
return method.DeclaringType.GetProperties()
.Where(prop => prop.GetSetMethod() == method).FirstOrDefault();
}
else
{
return method.DeclaringType.GetProperties()
.Where(prop => prop.GetGetMethod() == method).FirstOrDefault();
}
}
Then in my IInterceptor:
#region IInterceptor Members
public void Intercept(IInvocation invocation)
{
bool doSomething = invocation.Method.GetProperty().GetCustomAttributes(true).OfType<SomeAttribute>().Count() > 0;
}
#endregion
Thanks.
