Why is JsonRequestBehavior needed?

Why is Json Request Behavior needed? If I want to restrict the HttpGet requests to my action I can decorate the action with the [HttpPost] attribute Example: [HttpPost] public JsonResult Foo() { return Json("Secrets"); } // Instead of: public JsonResult Foo() { return Json("Secrets", JsonRequestBehavior.AllowGet); } Why isn't [HttpPost] sufficient? Why the framework "bug

为什么需要JsonRequestBehavior?

为什么需要Json Request Behavior ? 如果我想限制HttpGet请求到我的动作,我可以用[HttpPost]属性来修饰动作 例: [HttpPost] public JsonResult Foo() { return Json("Secrets"); } // Instead of: public JsonResult Foo() { return Json("Secrets", JsonRequestBehavior.AllowGet); } 为什么不是[HttpPost]足够? 为什么框架为我们所拥有的每个JsonResult提供了JsonRequestBehavior.AllowGet 。 如果我想

How to validate X.509 Certificate in C# using Compact Framework

I am trying to validate an X.509 certificate using C# and .NetCF. I have the CA certificate, and if I understand correctly, I need to use the public key from this CA certificate to decrypt the signature of the untrusted certificate. This should give me the computed hash value of the untrusted certificate. I should then compute the hash of the certificate myself and make sure the two values mat

如何使用Compact Framework在C#中验证X.509证书

我正在尝试使用C#和.NetCF来验证X.509证书。 我有CA证书,如果我理解正确,我需要使用此CA证书中的公钥来解密不可信证书的签名。 这应该给我不可信证书的计算哈希值。 然后我应该自己计算证书的散列值,并确保两个值匹配。 我一直在玩这个几天,而且我没有走得很远。 我一直在使用X509Certificate和RSACryptoServiceProvider类。 首先,我试图从X509Certificate类中获取公钥和签名。 我能够获得公钥,但没有签名。 接

Implementing reactive programming/functions in c#

I was recently reading up about game engine design and eventually ended up stumbling upon this: What is (functional) reactive programming? I was wondering how exactly one would implement the example given in the 2nd highest rated answer. In C++ it'd be easy enough passing a pointer to the value that stores the mouse coordinates, and just returning the value of that instead of the int. Wel

在c#中实现反应式编程/函数

最近我正在阅读关于游戏引擎设计的书籍,最终终于绊倒了这一点:什么是(功能性)反应式编程? 我想知道如何实现第二个最高评分答案中给出的例子。 在C ++中,将指针传递给存储鼠标坐标的值很容易,只是返回值而不是int。 那么,我们不能在C#中真正做到这一点,所以我们的第一个问题。 我们是否需要调用一些“更新”功能来保持所有值都是最新的? 其次是如何处理语法? 分配值很简单。 但做每次我要求的时候,“从我们这

Help a C# developer understand: What is a monad?

There is a lot of talk about monads these days. I have read a few articles / blog posts, but I can't go far enough with their examples to fully grasp the concept. The reason is that monads are a functional language concept, and thus the examples are in languages I haven't worked with (since I haven't used a functional language in depth). I can't grasp the syntax deeply enough t

帮助C#开发人员理解:什么是monad?

这些天有很多关于monad的讨论。 我已经阅读了一些文章/博客文章,但我无法用他们的例子去充分掌握这个概念。 原因是monad是一个功能性语言概念,因此这些例子都是我没有使用过的语言(因为我没有深入地使用函数式语言)。 我无法深入地理解语法以充分跟踪文章......但我可以告诉那里有值得理解的东西。 但是,我非常了解C#,包括lambda表达式和其他功能特性。 我知道C#只有一部分功能特性,所以也许monad不能用C#表达。

What is the compelling scenario for using Monads in C#

Let me state up front that I have an infantile understanding of Monads. I have read the various threads on Monads here and have done a few hours of study on the concept. I hardly feel comfortable with the term, but I think it is safe to say that I generally understand what a Monad is/does. I'm a C# developer who is looking to improve the way I work. What would help me further in my Monad

在C#中使用Monads有什么吸引人的场景

让我先说一说,我对Monad有一个幼稚的理解。 我已经阅读Monad上的各种线索,并对这个概念进行了几个小时的研究。 我对这个术语感到不太舒服,但我认为可以肯定地说我一般都明白Monad是什么。 我是一名C#开发人员,希望改善我的工作方式。 什么可以帮助我进一步在我的Monaducation中看到一个Monad在C#中的真实世界应用(即通过linq SelectMany()或者其他),这明显比其他解决oldskool C#中相同类型问题的方法有所改进。

Reflection support in C

I know it is not supported, but I am wondering if there are any tricks around it. Any tips? Reflection in general is a means for a program to analyze the structure of some code. This analysis is used to change the effective behavior of the code. Reflection as analysis is generally very weak; usually it can only provide access to function and field names. This weakness comes from the langu

C中的反射支持

我知道它不被支持,但我想知道是否有任何技巧。 有小费吗? 一般来说,反思是程序分析某些代码结构的手段。 此分析用于更改代码的有效行为。 作为分析的反思通常非常薄弱; 通常它只能提供对函数和字段名称的访问。 这种弱点来自于语言实现者,他们基本上不希望在运行时使完整的源代码可用,以及适当的分析例程以从源代码中提取想要的东西。 另一种方法是通过使用强大的程序分析工具来处理程序分析,例如,可以按照编译

Unboxing uint/int without knowing what's inside the box

I have an object o that is known to be a boxed int or uint : object o = int.MinValue object o = (uint)int.MinValue // same bytes as above I don't know what's in the box, all I care about is that there's 4 bytes in there that I want to coerce to an int or uint . This works fine in an unchecked context when I have values (instead of boxes): unchecked { int a = (int)0x80000000u;

在不知道盒子里面有什么的情况下拆箱uint / int

我有一个object o被称为是一个盒装int或uint : object o = int.MinValue object o = (uint)int.MinValue // same bytes as above 我不知道盒子里有什么,我只关心那里有4个字节,我想强制为int或uint 。 当我有值(而不是框)时,这可以在unchecked上下文中正常工作: unchecked { int a = (int)0x80000000u; // will be int.MinValue, the literal is a uint uint b = (uint)int.MinValue; } 注意:默认情况下,C

用POCO和t4模板测试EF 4.0

我试图创建假的上下文相关http://blogs.msdn.com/b/adonet/archive/2009/12/17/walkthrough-test-driven-development-with-the-entity-framework-4- 0.aspx 正如我所看到的,有一个接口公开了返回IObjectSet <...>的方法,但T4模板生成的方法返回ObjectSet <...>并且没有生成接口,并且在该页面上,作者将接口添加到创建的上下文中它给他的方式来创建模拟等。 我的主要目标是使用T4模板来生成poco类并创建模拟/

Query for accurate and localized list of installed Windows updates

How can I query for an accurate and localized list of Windows updates installed on a machine using C#? I define accurate as matching what is displayed in the "Microsoft Windows" category of Microsoft's View Installed Updates dialog under Programs and Features in Windows 7. If I use WUApi.DLL, the information is returned localized but I can't get an accurate list. In the cas

查询安装的Windows更新的准确和本地化列表

我如何查询使用C#在计算机上安装的Windows更新的准确和本地化列表? 我将其精确定义为匹配Windows 7中“程序和功能”下Microsoft的“查看安装的更新”对话框的“Microsoft Windows”类别中显示的内容。 如果我使用WUApi.DLL,信息将返回本地化,但我无法获得准确的列表。 对于WUApi.dll,缺少一些修补程序,如果更新已被卸载,它仍然显示在由以下代码生成的列表中: public static void GetWindowsUpdates() { var updateS

How to avoid recursive triggering of events in WPF?

I am having two WPF (from the standard set) widgets A and B. When I change some property of A it should be set on B, when it is change in B it should be set on A. Now I have this ugly recursion --> I change A, so code changes B, but since B is changed, it changes A, so it changes B... You have the picture. How to avoid this recursion the most "standard" way? Naive deleting and a

如何避免WPF中事件的递归触发?

我有两个WPF(来自标准集)小部件A和B.当我更改A的某个属性时,它应该设置在B上,当它在B中更改时,它应该设置为A. 现在我有这个丑陋的递归 - >我改变了A,所以代码改变了B,但是因为B改变了,它改变了A,所以它改变了B ...你有图片。 如何避免这种递归最“标准”的方式? 天真的删除和添加事件处理程序不起作用,并且检查新值是否与旧值相同在此不适用(由于计算的波动 - 我没有将相同的值设置为A和B,而是进行了转换)
