How to implement a generic parameter that isn't generic

I have an interface with two generic parameters, but one of the parameters is expected to be provided by the class implementation. public interface IA<T, U> { ... } public class X<T> : IA<T, int> { ... } public class Y<T> : IA<T, MyClass> { ... } However, another interface have a method that takes an instance of IA as a parameter - however, every instance must be t

如何实现不通用的通用参数

我有两个通用参数的接口,但其中一个参数预计由类实现提供。 public interface IA<T, U> { ... } public class X<T> : IA<T, int> { ... } public class Y<T> : IA<T, MyClass> { ... } 然而,另一个接口有一个将IA的实例作为参数的方法 - 但是,每个实例必须是相同的(同一个类可以接受多个X ,但不会接受Y ,反之亦然)。 我试图把它作为一个通用约束,但是我有类似的东西 public interface

Sanitize user inputs destined for email

I am considering the xss sanitization of user-supplied inputs gathered from an Internet-facing ASP.NET MVC5 web site. Sanitizing such inputs when presenting them back in a browser is well-documented and catered for. However, I haven't found reputable guidelines for how best to handle sanitization in the context of constructing emails which contain said user-supplied values. By default, I

清理用于输入电子邮件的用户输入

我正在考虑从面向Internet的ASP.NET MVC5网站收集的用户提供的输入的xss消毒。 在将这些输入提交回浏览器时对这些输入进行消毒处理是有充分文件记录的。 但是,在构建包含用户提供的值的电子邮件的环境中,我还没有找到如何最好地处理消毒的信誉指南。 默认情况下,我将发送纯文本消息,这表明我不需要对这些值进行HTML编码。 但是,我担心现代邮件客户端会尝试呈现HTML格式的任何HTML格式。 我可以只用HtmlEncode编码所

client security with web control in CMS

Scenario: We have developed a wcf web service which links to a database inside our firewall / dmz. The web service and client application (data capture web forms) are required to be hosted on our internet facing web server. This is because it needs to be accessed by web controls that will be hosted by our third party CMS (host our main website). Issue: We want to ensure the data can be pa

在CMS中使用网页控制的客户端安全

场景: 我们开发了一个wcf web服务,该服务链接到防火墙/ dmz中的数据库。 Web服务和客户端应用程序(数据捕获Web表单)需要在我们面向互联网的Web服务器上托管。 这是因为它需要通过我们的第三方CMS(托管我们的主网站)托管的网页控件访问。 问题: 我们希望确保数据可以尽可能安全地传递,但我们会对我们与CMS提供商之间的共享证书保持谨慎(反之亦然)。 我们希望网页控制托管为https,但我已阅读的所有文档都说这

many servers, one client

I'm planning on deploying a WCF service to multiple devices to receive notifications of certain events. All of the events will originate from a client machine that can provide a certificate to the service to authenticate. I'm less concerned about the client authenticating each service, but I'm having difficulty choosing the proper WCF security settings to provide this setup. It ap

许多服务器,一个客户端

我打算将WCF服务部署到多个设备以接收某些事件的通知。 所有这些事件将来自客户端机器,可以向服务提供证书以进行身份​​验证。 我不太关心客户端对每项服务进行身份验证,但我很难选择适当的WCF安全设置来提供此设置。 看来,消息级安全性需要客户端证书和服务证书。 但托管该服务的设备将无法维护,因此无法在服务证书到期时定期更新服务证书。 所以这里是我的问题: 有没有办法在服务器上没有服务证书的情况下为客户

WPF c# outlook sendEventHandler with parameters

I´m creating a mail item and adding the sendEventHandler, what I need is to pass a list as parameter when calling the method inside the event. My code: private void method() { ...

Why should casting be avoided?

I generally avoid casting types as much as possible since I am under the impression that it's poor coding practice and may incur a performance penalty. But if someone asked me to explain why exactly that is, i would probably look at them like a deer in headlights. So why/when is casting bad? Is it general for java, c#, c++ or does every different runtime environment deal with it on it&#

为什么要避免铸造?

我通常尽可能避免使用类型,因为我认为这是糟糕的编码习惯,可能会导致性能损失。 但是如果有人问我解释为什么那样,我可能会把他们看成是头灯上的鹿。 那么为什么/何时投射不好? 它是一般的Java,C#,C ++还是每个不同的运行时环境自己处理它? 欢迎使用任何语言的具体细节,例如为什么它在c ++中不好? 你用三种语言标记了这三种语言,答案在三者之间真的很不一样。 对C ++的讨论或多或少意味着对C剧组的讨论,并

How much null checking is enough?

What are some guidelines for when it is not necessary to check for a null? A lot of the inherited code I've been working on as of late has null-checks ad nauseam. Null checks on trivial functions, null checks on API calls that state non-null returns, etc. In some cases, the null-checks are reasonable, but in many places a null is not a reasonable expectation. I've heard a number of a

多少空值检查就足够了?

什么是什么是什么时候没有必要检查空值的指导原则? 最近我一直在研究的很多继承代码都有空的检查和恶心。 对平凡函数进行空检查,对调用非空返回的API调用进行空检查等。在某些情况下,空检查是合理的,但在很多地方,空值不是合理的期望值。 我听到过许多争论,从“你不能相信其他代码”到“始终防守”,直到“在语言保证我是非空值的前提下,我总是会去检查。” 我当然同意这些原则中的许多原则,但我发现过多的空值检查会导

Replacing .NET WebBrowser control with a better browser, like Chrome?

Is there any relatively easy way to insert a modern browser into a .NET application? As far as I understand, the WebBrowser control is a wrapper for IE , which wouldn't be a problem except that it looks like it is a very old version of IE , with all that entails in terms of CSS screw-ups, potential security risks (if the rendering engine wasn't patched, can I really expect the zillion b

用更好的浏览器替代.NET WebBrowser控件,如Chrome?

是否有任何相对简单的方法将现代浏览器插入到.NET应用程序中? 据我所知, WebBrowser控件是IE的包装,除了它看起来是一个非常旧的IE版本之外,这不会成为问题,所有这一切都需要通过CSS拧紧,潜在的安全性风险(如果渲染引擎没有打补丁,我真的可以期望缓冲区溢出问题得到解决吗?)和其他问题。 我正在使用Visual Studio C#(快速版 - 它在这里有什么区别?) 我想在我的应用程序中集成好的网络浏览器。 在某些情况下
