在运行MVC3中的每个Action之前,我们如何运行一个方法？
我知道我们可以使用以下方法进行OnActionExecuting：
public class ValidateUserSessionFilterAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
...
}
}
但是,如何在ActionExecuting之前运行方法？
解决方法
你正在寻找
Controller.ExecuteCore().
在每个动作调用之前调用此函数.您可以在控制器或基本控制器中覆盖它.从Nadeem Afana设置基于Cookie的文化的示例：
public class BaseController : Controller
{
protected override void ExecuteCore()
{
string cultureName = null;
// Attempt to read the culture cookie from Request
HttpCookie cultureCookie = Request.Cookies["_culture"];
if (cultureCookie != null)
{
cultureName = cultureCookie.Value;
}
else
{
if (Request.UserLanguages != null)
{
cultureName = Request.UserLanguages[0]; // obtain it from HTTP header AcceptLanguages
}
else
{
cultureName = "en-US"; // Default value
}
}
// Validate culture name
cultureName = CultureHelper.GetImplementedCulture(cultureName); // This is safe
// Modify current thread's cultures
Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cultureName);
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
base.ExecuteCore();
}
}
