如果在action方法中有一个model-bound参数,那么你如何在action过滤器中得到该参数呢？
[MyActionFilter]
public ActionResult Edit(Car myCar)
{
...
}
public class MyActionFilterAttribute : ActionFilterAttribute
{
public void OnActionExecuted(ActionExecutedContext filterContext)
{
//I want to access myCar here
}
}
有没有通过Form变量获取myCar？
解决方法
不确定OnActionExecuted,但可以在OnActionExecuting中执行：
public class MyActionFilterAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
// I want to access myCar here
if(filterContext.ActionParameters.ContainsKey("myCar"))
{
var myCar = filterContext.ActionParameters["myCar"] as Car;
if(myCar != null)
{
// You can access myCar here
}
}
}
}
