问题 Imagine a view bag called ViewBag.Modes this contains the following: Simple Advanced Manual Complete How can I access the viewbag by index like you would in an array? e.g Simple is at index 0 then it would look like this ViewBag.Modes[0] I tried the above but it doesn't work so...How can I replicate this with viewbag or is there a workaround I can use? 回答1: This does the trick for me: Controller: public ActionResult Index() { var stringArray = new string[3] { "Manual", "Semi", "Auto"};

问题 Using VS 2017 with MVC 5 Razor views. When I publish my application, a handful of specific views do not get copied over. I'd discovered several SE questions on this same issue from back in the 2010-2011 timeframe. At the time, the issue was that Build Action in the file's properties was not set to Content due to a bug in some early RC which has since been resolved. Well, all of mine already do day Content for Build Action. Any reason why only a small number of views are not making it in the

问题 I have @Html.Translate() extension method, which returns translated string. Translations are stored in database, so I want to make async call to database from helper method.

Is here some workaround to call async methods in razor view? 回答1: Async method calls from razor view are supported (or will be supported) only in ASP.NET vNext (MVC 6). If you are using MVC 5 version and eralier, the simplest solution to your problem would be adding a

问题 I am currently researching view engines and Razor Views have become very interesting to me. I am in process of developing an asp.net 4.0 web forms application. Razor views examples from what I could find are predominantly with MVC applications. Is it possible to integrate Razor views in to a web forms application? Is it beneficial to do so? The main reason I look to do this is to create a new layer for my applications architecture and possibly a new area that can be tested. 回答1: Of course you

问题 may I know hot can I write something like this c# Opendialog in Razor? I'm trying to make an openfiledialog that would offer user to upload photo into SqlServerCe database: OpenFileDialog openFileDialog1 = new OpenFileDialog(); openFileDialog1.InitialDirectory = "c:\\"; openFileDialog1.Filter = "All files (*.*)|*.*"; openFileDialog1.FilterIndex = 2; openFileDialog1.RestoreDirectory = true; if (openFileDialog1.ShowDialog() == DialogResult.OK) { try { string path = openFileDialog1.FileName;

问题 I make heavy use of the ViewBag in my MVC application, is this considered bad practice? I'm unsure as to whether to spend time creating ViewModels (however I thought that was more suited to MVVM rather than MVC) or continue using the ViewBag heavily. What are the arguments for and against this?

问题 I want my razor view to look something like this @Ajax.ActionLink("A", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-A" }) @Ajax.ActionLink("B", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-B" }) @Ajax.ActionLink("C", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-C" }) and my javascript to look something like this function updateLetter

问题 I have mail-merge like functionality, which takes a template, some business object, and produces html which is then made into PDF. I'm using RazorEngine to do the template+model to html bit. If I let the users specify the templates, what risks am I taking? Is it possible to mitigate any risks? For example, could the users execute arbitrary code? (delete files, alter database, etc.?) Is there some way I can detect this sort of thing? (I know that would be impossible generally, but the bits of

问题 This question already has answers here : Why use @Scripts.Render(“~/bundles/jquery”) (2 answers) Closed 6 years ago . I want to know about the difference between @Scripts.Render("~/something.js") and <script type="text/javascript" src="/something.js"></script> .
