I am fairly new to MVC and am really trying to a get used to the Model Binding. I have a simple model that i have created in a form. However, when i post that form ONLY the textbox values are carrying over to the controller. I need the description field also which is done using DisplayTextFor. Is this something i am going to have to make a custom model binder for? I could take a shortcut and
我对MVC相当陌生，我真的想要习惯模型绑定。 我有一个简单的模型，我创建了一个表单。 但是，当我只发布该表单的文本框值传递给控制器。 我还需要使用DisplayTextFor完成的描述字段。 这是我将不得不做一个自定义模型绑定器？ 我可以采取一个快捷方式，只是使描述为无边框只读文本框，所以它看起来像文本，但我想要做到这一点正确的方式。 这是我的代码： public class FullOrder { public List<FullOrderItem>
Possible Duplicate: Does C# optimize the concatenation of string literals? string foo = "bar1" + "bar2" + "bar3"; Does the c# compiler internally apply the string.Concat method ? Then it would be better to use the + operator for the readability sake. With literals, this is equivalent to: string foo = "bar1bar2bar3"; No concatenation is performed- they are combined at compile time into a
可能重复： C＃是否优化了字符串文字的连接？ string foo = "bar1" + "bar2" + "bar3"; c＃编译器是否内部应用了string.Concat方法？ 为了可读性，最好使用+运算符。 对于文字，这相当于： string foo = "bar1bar2bar3"; 没有连接被执行 - 它们在编译时被组合成一个常量。

I am designing a website that will upload video files in ASP.NET. The question I have is: video files can get very huge (ie 3GB) and I read that increasing the maxRequestLength in the webconfig file will give the chance for hackers to attack the server with large requests. I already know about client validation to protect from malicious files that are not the intended files, so that's not
我正在设计一个将在ASP.NET中上传视频文件的网站。 我的问题是：视频文件可能会变得非常巨大（例如3GB），我读到在webconfig文件中增加maxRequestLength会给黑客攻击大量请求的服务器的机会。 我已经知道客户端验证以防止不是预期文件的恶意文件，所以目前这不是问题。 我的问题是，如果文件上传方法是上传视频文件的正确方法？ 如果没有，是否有更好的方法？ 为了在asp.net中上传大文件，我使用了“Brettle.Web.NeatUploa

Short story: A ListBox inside a focus scope doesn't allow an item to be selected. Long story: I am trying to make a context-sensitive widget for data entry. I have the main panel with several fields. Below that, I have a panel with FocusManager.FocusScope="True" . This panel will be filled with the relevant widget for the field which currently has focus. For example, selecti
小故事：焦点范围内的ListBox不允许选择项目。 很长的故事： 我正在尝试为数据输入创建一个上下文敏感的小部件。 我有几个领域的主面板。 在那之下，我有一个FocusManager.FocusScope="True"的面板。 此面板将填充当前具有焦点的相关窗口小部件。 例如，选择日期字段将在屏幕底部显示日历。 我有几个控件，要求用户从列表中选择多个值中的一个。 我把一个列表框放到焦点范围内，但我不能选择任何项目。 当
After having read the documentation for the Dispatcher class, I realize that it can be used for non-UI queueing of actions too. So how does the Dispatcher class actually works? I'm aware of that, it's main job is to queue actions to a specific thread - but how does it "send" those actions to the thread? And how do the thread "get" these actions? My best guess is
在阅读Dispatcher类的文档之后，我意识到它也可以用于非UI排队的操作。 那么Dispatcher类实际上如何工作？ 我意识到这一点，主要的工作是将动作排队到特定的线程 - 但它如何将这些动作“发送”到线程？ 线程如何“获取”这些操作？ 我最好的猜测是每个线程都有一些“线程队列”，但是我再也不知道了。 让一个线程开始执行代码到另一个线程并不是一件容易的事情。 问题的关键是你不能简单地告诉任何线程在该线程已经启动之后开

If I wanted to create an expression tree that called a method with an out parameter and then returned the out value as a result.. how would I go about it? The following does not work (throws a runtime exception), but perhaps best demonstrates what I'm trying to do: private delegate void MyDelegate(out int value); private static Func<int> Wrap(MyDelegate dele) { MethodInfo fn = de
如果我想创建一个表达式树，用一个out参数调用一个方法，然后返回out值作为结果..我该如何去做呢？ 以下不起作用（引发运行时异常），但也许最好地演示了我正在尝试做的事情： private delegate void MyDelegate(out int value); private static Func<int> Wrap(MyDelegate dele) { MethodInfo fn = dele.Method; ParameterExpression result = ParameterExpression.Variable(typeof(int)); BlockExpression
