Red Black Tree in C#

brent — Fri, 28 Apr 2017 21:02:00 GMT

Several weeks ago, I tried hard to search an implement of balance binary tree in C#, what i needed was something like std::set in C++: the data should be sorted, can be inserted and deleted at low cost and provides iterator which can move forward and backward. It looks like this can be easily achieved by List with List.Sort and List.BinarySearch, the problem is that the performance of List is not acceptable when the data collection size is big in my case.

I failed to find anything that can be used directly, it is hard to believe, a lot of implement of red-black tree in Java or C++ can be easily got from internet (although none of them meets my requirement), but none in C#.

So I had to implement one, it was translated from a C++ implement and modified to provide an immutable node.

Use at your own risk!

Example:

1 RBTree<int> rbt = new RBTree<int>(Comparer<int>.Default);
2         rbt.Add(3);
3         rbt.Add(1);
4         rbt.Add(10);
5         rbt.Add(6);
6         rbt.Add(7);
7         rbt.Remove(10);
8         RBNode<int> node6 = rbt.GetNode(6);
9         rbt.Remove(node6);
10
11         RBNode<int> node = rbt.GetNode(3);
12         node = node.Prev;
13         while (null != node)
14         {
15             System.Diagnostics.Trace.WriteLine(node.Value);
16             node = node.Next;
17         }

使用ASP.net + WF的感受

brent — Mon, 06 Apr 2009 10:30:00 GMT

两个多星期的努力，终于把Prototype搞定了。实现了以下功能：

1，一个state machine workflow(Fund Request Process work flow)
2，使用Polic来控制业务逻辑
3，实现了xoml和dll的分离，动态加载xoml，提供一个编辑工具，可以edit the workflow on-the-fly

1, 并没有传说中的那么难
ASP.net和WF我都不熟，根据两本书，一个msdn上的例子"Web Form Workflow Approvals Stater kit"和另一个例子Orders http://www.odetocode.com/Articles/465.aspx的基础上把prototype搞出来了。

2，理解概念很重要
如果不理解WF是怎么调用外部函数（CallExternalMethodActivity），是怎么传Event给WF（HandleExternalEventActivity），DependencyProperty是怎么回事，基本不用再搞了。

3，很多设计可做
WF只实现了workflow最内核的部分，非常灵活。同样的实现可以采用完全不同的实现方式。怎么实现workflow definition，怎么设计Activities，需要为Activities添加那些DependencyProperty，这些DependencyProperty是怎么互相关联的，怎么只在xoml里面保存workflow definition，怎么实现Workflow和业务数据的交互，怎么实现Workflow和组织结构或者role的关联，都可以有完全不同的设计。

4，还有很多概念。。
因为是prototype，很多东西没考虑，比如事务transation或者Compensate，异常处理等。

-_- 释放托管资源？

brent — Wed, 08 Oct 2008 09:06:00 GMT

有一本书叫《Effective C#》，被翻译了，里面有一章叫《实现标准Dispose模式》，里面有一句话叫做：

"释放托管资源"。莫非是"release managed resource"?

什么叫做释放托管资源(release managed resource)? 莫非是把成员的引用设置为null?

一般来说如果一个对象被dispose了，那它也要马上人间蒸发了，GC从全局变量和栈里面就要找不到它了，更不要说它的内部成员变量了，这时候设置它的成员为null有什么必要呢？

看了MSDN才知道，人家是"dispose managed resource"，就是调用managed的对象的dispose方法。

太囧了，无法用中文表达。

有牛人在研究用中文写程序，为什么IG诺贝尔奖不颁发给它呢？同时，我终于知道为什么英文影印版的书比中文翻译版的要贵了。

Exposing Windows Forms Controls as ActiveX controls

UserControl is not enough sometimes.
Sometimes you need to Expose a Form to ActiveX. Just don't forget to set it's TopLevel to false.
And it seems that a Form as MDI Container can't be exposed to ActiveX.Be aware of this if you want to expose your application to ActiveX.

Ok, you get through happily, and you should distribute you activex control now. Generate a cab file and put it on you web-server? No.
You have to do some ugly thing before it works. God will get very angry with this.
