Lets say I have the following class structure in my data access layer: interface IBehavior<in T> { void Load(T model); } class ModelManager<T> { ModelManager(IEnumerable<IBehavior<T>> behaviors) { ... } void Load(T model) { foreach (var behavior in behaviors) { behavior.Load(model) } } } This lets me have various interfaces that my models can im
比方说，我有我的数据访问层中的以下类结构： interface IBehavior<in T> { void Load(T model); } class ModelManager<T> { ModelManager(IEnumerable<IBehavior<T>> behaviors) { ... } void Load(T model) { foreach (var behavior in behaviors) { behavior.Load(model) } } } 这可以让我有我的模型可以实现的各种接口，以及处理这些接口的可重用行为： interface IUni
Since multiple inheritance is bad (it makes the source more complicated) C# does not provide such a pattern directly. But sometimes it would be helpful to have this ability. For instance I'm able to implement the missing multiple inheritance pattern using interfaces and three classes like that: public interface IFirst { void FirstMethod(); } public interface ISecond { void SecondMethod();
由于多重继承是不好的（它使得源代码更加复杂），C＃不直接提供这样的模式。 但有时候这会有所帮助。 例如，我能够使用接口和三个类来实现缺少的多重继承模式： public interface IFirst { void FirstMethod(); } public interface ISecond { void SecondMethod(); } public class First:IFirst { public void FirstMethod() { Console.WriteLine("First"); } } public class Second:ISecond { public void Se
I have a class that I want to use to store "properties" for another class. These properties simply have a name and a value. Ideally, what I would like is to be able to add typed properties, so that the "value" returned is always of the type that I want it to be. The type should always be a primitive. This class subclasses an abstract class which basically stores the name
我有一个我想用来存储另一个类的“属性”的类。 这些属性只有一个名称和一个值。 理想情况下，我希望能够添加类型化属性，以便返回的“值”始终是我希望的类型。 该类型应该始终是原始的。 这个类继承了一个抽象类，它基本上将字符串的名称和值存储起来。 这个想法是，这个子类将为基类增加一些类型安全性（以及节省我的一些转换）。 所以，我创建了一个类（大致）： public class TypedProperty<DataType> : Property
I have looked and searched for ways to disable indentation of comments when I save C# files in Visual Studio 2015 with Resharper 9.0.0.0 installed. I'd like to pseudocode before I start writing actual code. However I have been tweaking with both Visual studio's and Resharper's settings to no avail. So for example I want the comments to look like: private string ToggleString(str
当我在安装了Resharper 9.0.0.0的Visual Studio 2015中保存C＃文件时，我查找并搜索了禁用注释缩进的方法。 在开始编写实际代码之前，我想伪代码。 不过，我一直在调整Visual Studio和Resharper的设置，但都无济于事。 举个例子，我想让评论看起来像这样： private string ToggleString(string input) { // If input.length is between 1-100 // All the uppercase letters converted to lowercas

这个问题在这里已经有了答案： 如何找到算法的时间复杂度10个答案 大O，你如何计算/估计它？ 22个答案 找到谐波系列3的答案 外循环运行n次。 对于每次迭代，内部循环运行n / i次。 总运行次数是： n + n/2 + n/3 + ... + n/n 渐近地（忽略整数算术舍入），这简化为 n * (1 + 1/2 + 1/3 + ... + 1/n) 这个系列松散地收敛于n * log(n) 。 因此，复杂度是O（N.log（N）），如你所料。 第一个内部循环运行n次
I've had an annoying issue with focus for controls on a ToolBar in WPF. My toolbar has a CheckBox and a TextBox control next to eachother. If you click and edit the text in the text box, then click the check box, the text box steals the focus back after clicking the check box, and the check box state is not changed when the user clicks on it. I have similar issues with text boxes all over
我有一个讨厌的问题，关注WPF中ToolBar的控件。 我的工具栏旁边有一个CheckBox和一个TextBox控件。 如果您单击并编辑文本框中的文本，然后单击复选框，单击该复选框后文本框会将焦点移回，并且复选框状态在用户单击时不会更改。 我在我的应用程序中遇到了与文本框相似的问题，但我相信这是最简单的案例，我希望这个问题会成为所有文本框中的常见问题。 有人知道这里可能会发生什么吗？ 将处理程序连接到复选框的Click事件
I am trying to develop a touchscreen keyboard control in a C# WPF project that will be visible when a TextBox gets focus and is hidden when the TextBox loses focus. The projects I have seen for touchscreen keyboards have accomplished this by defining the keyboard as a new window rather than a control. For my application, I would really like to have the keyboard as a control within the main app
我正在尝试在C＃WPF项目中开发一个触摸屏键盘控件，当TextBox获得焦点时它将可见，并且在TextBox失去焦点时隐藏。 我见过的触摸屏键盘项目已经通过将键盘定义为新窗口而不是控件来实现这一点。 对于我的应用程序，我真的希望将键盘作为主应用程序窗口中的控件。 有没有办法让一个按钮被点击（在键盘控件上）而不会导致TextBox失去焦点？ 理想情况下，我想在克拉的当前位置放置一个角色。 在按钮上设置Focusable="Fal
