摘要： ---恢复内容开始---IntroductionThere are several ways of doing asynchronous programming in .Net. Visual Studio 2012 introduces a new approach using the ‘await’ and ‘async’ keywords. These tell the compiler to construct task continuations in quite an unusual way.I found them quite difficult to understand us 阅读全文

摘要： I thought of naming this post “Evolution of lambdas in C#”, then I decided that wouldn’t be closest appropriate name for the example that I wanted to discuss. The key to understand a lambda in C# is to understand a delegate. Besides the overly blatant blather – “delegates are nothing but function po 阅读全文

摘要： There is no such thing like impossible in software development. Impossible just takes longer.I've investigated the problem. If there is really need for Flow Layout, it can be done with a bit of work. Since FlowLayoutPanel lays out the controls without particularly thinking about the number of ro 阅读全文

摘要： have a problem with a FlowLayoutPanel and I don't know how to solve it.I'm placing two FlowLayoutPanels inside another; the second inner flp has 3 buttons inside.The properties from FlowLayoutPanel child are:FlowDirection=LeftToRight;AutoSize=true;AutoSizeMode=GrowAndShrink;WrapContents=true 阅读全文

摘要： Well, the easiest way would be to retain an explicit reference to the buttons you're adding. Otherwise you could add a tag to distinguish them (to be robust against i18n issues). E.g. you can set the tag of "button2" to "button2" and then you can use:foreach(Control ctl in fl 阅读全文

摘要： For a FlowLayoutPanel, you don't need to specify a location since the controls are arranged for you. Just change "this" to the name of your FlowLayoutPanel:for (int i = 0; i < 5; i++){ Button button = new Button(); button.Tag = i; flowLayoutPanel1.Controls.Add(button);}////Populatin 阅读全文

摘要： 跨AppDomain通信有两种方式 1.Marshal By reference : 传递引用 2.Marshal By Value : 把需要传递的对象 通过序列化反序列化的方式传递过去(值拷贝) 只有标记为 可序列化 Serializable 的类才能通过 Marshal By Value的方式通信以下代码描述了几种跨域通信的情况1.AppDomain是CLR的内部行为,windows完全不清楚有AppDomain的存在2.在新的域中加载Assembly和Type最好用完整限定名(如果直接加载Type, CLR会自动加载Type所在的和所用到的Assembly)3.默认情况下新建... 阅读全文

摘要： 应用程序域（AppDomain）已经不是一个新名词了，只要熟悉.net的都知道它的存在，不过我们还是先一起来重新认识下应用程序域吧，究竟它是何方神圣。应用程序域 众所周知，进程是代码执行和资源分配的最小单元，每个进程都拥有独立的内存单元，而进程之间又是相互隔离的，自然而然，进程成为了代码执行的安全边界。 一个进程对应一个应用程序是一个普遍的认知，而.net却打破了这一惯例，因为它带来了应用程序域这一全新的概念，CLR可使用应用程序域来提供应用程序 之间的隔离，而一个进程中可以运行多个应用程序域，也就是说只要使用应用程序域，我们可以在一个进程中运行多个应用程序，而不会造成进程间调用或进程间切 换 阅读全文
