Use*_*ser 19 asp.net-mvc mvccontrib url-redirection
由于我现在决定让RC继续使用Beta,我无法知道是否RedirectToAction添加了强类型.是否有人尝试过它并且在RC中是否存在强类型RedirectToAction(也许ActionLink)?

不,它没有.
protected RedirectToRouteResult RedirectToAction<T>(Expression<Action<T>> action, RouteValueDictionary values) where T : Controller
{
var body = action.Body as MethodCallExpression;
if (body == null)
{
throw new ArgumentException("Expression must be a method call.");
}
if (body.Object != action.Parameters[0])
{
throw new ArgumentException("Method call must target lambda argument.");
}
string actionName = body.Method.Name;
var attributes = body.Method.GetCustomAttributes(typeof(ActionNameAttribute), false);
if (attributes.Length > 0)
{
var actionNameAttr = (ActionNameAttribute)attributes[0];
actionName = actionNameAttr.Name;
}
string controllerName = typeof(T).Name;
if (controllerName.EndsWith("Controller", StringComparison.OrdinalIgnoreCase))
{
controllerName = controllerName.Remove(controllerName.Length - 10, 10);
}
RouteValueDictionary defaults = LinkBuilder.BuildParameterValuesFromExpression(body) ?? new RouteValueDictionary();
values = values ?? new RouteValueDictionary();
values.Add("controller", controllerName);
values.Add("action", actionName);
if (defaults != null)
{
foreach (var pair in defaults.Where(p => p.Value != null))
{
values.Add(pair.Key, pair.Value);
}
}
return new RedirectToRouteResult(values);
}
