问题 For an ASP.NET MVC application, can someone explain to me why calls to Html.BeginForm begin with the statement @using ? Example - @using (Html.BeginForm()) { //Stuff in the form } I thought @using statements are for including namespaces. Thanks! 回答1: Using Statement provides a convenient syntax that ensures the correct use of IDisposable objects. Since the BeginForm helper implements the IDisposable interface you can use the using keyword with it. In that case, the method renders the closing

问题 I'm fairly new to ASP.NET MVC and am trying to work out the best way to do this. It's probably simple but I just want to do things correctly so I thought I'd ask. Lets say I have a model that is this: Task - Id, Description, AssignedStaffMember StaffMember - Id, FirstName, LastName and in my view I want to create a new task. I make a strongly typed Razor view, and can use EditorFor to create textboxes for Description but what about AssignedStaffMember? I want a drop down list of all current

问题 How can I use Razor in CSS files? I'm using Razor View Engine for some time and I was curious about using it on style sheets. I can use Razor in <style> blocks of .cshtml files but I was wondering if I can use it in external .css files also (would like to have a .cscss format). So I googled it and found two things: The first one is LESS: "The dynamic stylesheet language". It seems easy-to-use and powerful with all the features but I need Razor-C#, really. The second is Dynamic CSS Using Razor

问题 This is the code which I have in my partial view @model Contoso.MvcApplication.Models.Exercises.AbsoluteArithmetic @using(Html.BeginForm()) { <div> <span style="width: 110px; float:left; text-align:center; font-size:2.5em;">@Model.Number1</span> <span style="width: 110px; float:left; text-align:center; font-size:2.5em;">+</span> <span style="width: 110px; float:left; text-align:center; font-size:2.5em;">@Model.Number2</span> <span style="width: 110px; float:left; text-align:center; font-size

问题 Is there a way for Visual Studio (I'm using 2010) to find errors within razor views during builds, in the same way as other code in a C# project would? It's just a pain that you can check any errors in your code and think that everything's fine, but it appears that you can't be sure about views unless you go through each one. BTW I obviously don't code in my views - I'm just talking about HTML or URL extension methods for example. 回答1: Try setting MVCBuildViews to true in your project file (i

问题 I’m working on the web app where the main page contains two parts: the constant block which is always visible and the info-block made up by one of 3 partial views. Each of the partial views appears as a result of AJAX request and is loaded just once (after that switching windows is provided by jquery). It works well but I’ve faced with one problem. The html-code of partial views contains js functions that are used in the constant block and in the info-block as well. When the page is loaded,
