LINQ扩展方法帮助寻求II

Question

有没有办法让我的视图中的这个扩展方法的参数'intellisensible'？

目前,我可以获得一个工具提示,指出参数(在控制器动作方法中)是什么,但是我很乐意自信地将IntelliSense键入"安全"的参数名称.无论如何,没有进一步的麻烦,方法,然后使用:

public static string Script<T>(this HtmlHelper html,
                                Expression<Action<T>> action) where T:Controller
{
    var call = action.Body as MethodCallExpression;

    if (call != null)
    {
        // paramDic - to be used later for routevalues
        var paramDic = new Dictionary<string, object>();
        string actionName = call.Method.Name;
        var methodParams = call.Method.GetParameters();

        if (methodParams.Any())
        {
            for (int index = 0; index < methodParams.Length; index++)
            {
                ParameterInfo parameterInfo = methodParams[index];
                Expression expression = call.Arguments[index];
                object objValue;
                var expressionConst = expression as ConstantExpression;
                if(expressionConst!=null)
                {
                    objValue = expressionConst.Value;
                }
                else
                {
                    Expression<Func<object>> expressionConstOther =
                        Expression.Lambda<Func<object>>(
                          Expression.Convert(expression, typeof(object)),
                          new ParameterExpression[0]);
                    objValue = expressionConstOther.Compile()();
                }
                paramDic.Add(parameterInfo.Name, objValue);
            }
        }
        string controllerName = typeof(T).Name;
        if (controllerName.EndsWith("Controller", StringComparison.OrdinalIgnoreCase))
        {
            controllerName = controllerName.Remove(controllerName.Length - 10, 10);
        }

        var routeValues = new RouteValueDictionary(paramDic);
        var urlHelper = new UrlHelper(html.ViewContext.RequestContext);
        var url = urlHelper.Action(actionName, controllerName, routeValues);

        const string linkFormat = "<script type=\"text/javascript\" src=\"{0}\"></script>";
        string link = string.Format(linkFormat, url);

        return link;
    }
    return null;
}

用法(FundShareholderController我的控制器在哪里,x.JsFile()是一个动作方法.):

<%=Html.Script<FundShareholderController>(x => x.JsFile("CreateInvestorBookingJsFile", 0))%>

我希望这是有道理的.如果您需要提供任何缺失的详细信息,请与我们联系.

BTW - 任何优化技巧也很乐意在船上进行.

尝试在方法上添加XML注释,如下所示.

/// <summary>
/// The summary of my Script Extension method.
/// </summary>
/// <typeparam name="T">T is the type of Controller</typeparam>
/// <param name="html">The HTML helper.</param>
/// <param name="action">The action Method of the Controller.</param>
/// <returns></returns>

将上述注释放在扩展方法后,我可以在IntelliSense中看到它们.见下图.
