Tree data structure in C#

I was looking for a tree or graph data structure in C# but I guess there isn't one provided. An Extensive Examination of Data Structures Using C# 2.0 explains a bit about why. Is there a convenient library which is commonly used to provide this functionality? Perhaps through a strategy pattern to solve the issues presented in the article. I feel a bit silly implementing my own tree, just

C#中的树数据结构

我在C#中查找树或图数据结构,但我想没有提供。 数据结构的广泛考察使用C#2.0解释了一些原因。 有没有一个通常用于提供此功能的便利库? 也许通过战略模式来解决文章中提出的问题。 我感觉有点无聊地实现我自己的树,就像我会实现我自己的ArrayList一样。 我只想要一个可能不平衡的通用树。 想想目录树。 C5看起来很漂亮,但它们的树结构似乎被实现为更适合于搜索的平衡红黑树,而不是代表节点的层次结构。 我最好

Why is volatile needed in C?

Why is volatile needed in C? What is it used for? What will it do? Volatile tells the compiler not to optimize anything that has to do with the volatile variable. There is only one reason to use it: When you interface with hardware. Let's say you have a little piece of hardware that is mapped into RAM somewhere and that has two addresses: a command port and a data port: typedef struc

为什么C中需要volatile?

为什么C中需要volatile ? 它是干什么用的? 它会做什么? Volatile告诉编译器不要优化任何与volatile变量有关的事情。 只有一个理由使用它:当你与硬件连接时。 假设您有一小块硬件映射到某处的RAM,并且有两个地址:一个命令端口和一个数据端口: typedef struct { int command; int data; int isbusy; } MyHardwareGadget; 现在你想发送一些命令: void SendCommand (MyHardwareGadget * gadget, int command

Writeablebitmap在异步调用中读取

我想将从UI(WPF)生成的writeablebitmap对象传递给异步调用,但不想更新主线程的writeablebitmap。 我只想读取一些属性,如像素高度和宽度。 在新线程中,我无法访问任何writeablebitmap的属性,因为它认为我试图混淆主线程的writeablebitmap的属性。 我收到异常:“调用线程不能访问此对象,因为不同的线程拥有它。” 其他线程中的一些响应提示他们使用Dispatcher.BeginInvoke ,但是如果我只是想要writeablebitmap对象的副
