csharp-commons
csharp公共库，包含集合等基础组件;nuget搜索'wjybxx'即可查看到相关库。
注意： 1.0.x 尚属于快速迭代版本，等基础工具基本完备的时候，会更新到 1.1.x 版本。因为我还有几个项目没有完成，会把遇见的一些基础工具迁移到这里，或在这里实现。
Collections
但凡C#的基础集合库好用一点，我也不至于自己造轮子，实现的集合类：
- LinkedDictionary 保持插入顺序的字典，并提供大量的有用方法。
- LinkedHashSet 保持插入顺序的Set，并提供大量的有用方法。
- IndexedPriorityQueue 含索引的优先级队列，高查询和删除效率。
- BoundedArrayDeque 基于数组的有界双端队列，允许手动调整容量。
- MultiChunkDeque 分块无界双端队列。
LinkedDictionary特殊接口示例：
public class LinkedDictionary<TKey,TValue> {
TKey PeekFirstKey();
TKey PeekLastKey();
void AddFirst(TKey key, TValue value);
void AddLast(TKey key, TValue value);
KeyValuePair<TKey, TValue> RemoveFirst();
KeyValuePair<TKey, TValue> RemoveLast();
TValue GetAndMoveToFirst(TKey key);
TValue GetAndMoveToLast(TKey key);
}
LinkedDictionary采用线性探测法解决hash冲突，通过在GetNode方法中记录线性探测次数，统计查询数据如下：
- 1W个int类型key，查询所有key，线性探测总次数 4000~5000， 平均值小于1
- 10W个int类型key，查询所有key，线性探测总次数 11000~12000，平均值小于1
- 1W个string类型key，长度24，查询所有key，线性探测总次数 4000~5000，平均值小于1 -- 与int相似，且调整长度几无变化。
- 10W个string类型key，长度24，查询所有key，线性探测总次数 11000~12000，平均值小于1 -- 与int相似，且调整长度几无变化。
Concurrent包
- 提供了Java的Executor和Future框架，并提供了对应的await语法支持。
- 提供了默认的EventLoop实现。
PS：c#端不打算再实现Disruptor库。
await语法的讨论
C#的Concurrent包，个人用得非常难受。究其原因：上下文(sync/execution)的传递是隐式的。这导致我们对线程和任务上下文的控制力度较弱，部分功能编写起来十分难受。
以我的使用经验来看，C#的await/async语法会导致这样的结果：使简单的问题更简单，使复杂的问题更复杂。
多线程编程从来都不是个简单问题，单线程语言的await/async不涉及复杂的线程和上下文切换问题，因此使用起来简单；
在多线程下，存在上下文和线程的控制问题，按照单线程语言async/await语法进行设计，只是让代码看起来简单了，实际上不论是语言的开发者，还是语言的使用者，面临的问题都更多了。
个人认为， 多线程下的await最佳实现应当允许传参，允许指定await后续操作的线程，以及其它调度选项。
