String對象和實值型別的記憶體配置機制: 同樣由前延伸,上上篇《由String類型分析,所產生的對參數傳遞之惑的解答》中,最後提及,如果將參考型別的按值傳遞和按引用傳遞,用託管堆表示,則更具說服力。在此附圖說明:(如果印象模糊,可回看文章) 由上兩圖可以看到:1.在圖1(即上面圖),當在按值傳遞參考型別參數時,接收參數的函數中(注意:依然在Stack上),依然存在一份拷貝——同樣指向原始字串("This is a String")的變數—funStr
The Barrier class is a signaling construct new to Framework 4.0. It implements a thread execution barrier, which allows many threads to rendezvous at a point in time. The class is very fast and efficient, and is built upon Wait, Pulse, and spinlocks.

At any time, a thread is said to be in one of several thread states (illustrated in Fig. 12.1)2. This section discusses these states and the transitions between states. Two classes critical for multithreaded applications
前言: 從TreeView,到GridView,再到Repeater,雖然曆經"折騰",然也對所學進行了一定的總結.在此對Repeater的使用作一概要. 解析: 使用方法同上篇博文<頁面與使用者控制項的值傳遞>,將gridview替換為Repeater控制項.後台代碼相同,即指定資料來源,然後綁定.前台代碼為: Code highlighting produced by Actipro CodeHighlighter
RegisterType假設我們有兩個介面ILogger,IStopLightTimer,對這兩個介面分別有兩個實現,TraceLogger,RealTimeTimer.The two interfaces are ILogger, which Unity maps to the concrete service class named TraceLogger, and IStoplightTimer, which Unity maps to the concrete service
The Pick activity provides event-based control modeling. It behaves similar to the C# switch statement, which executes only one of the branches in the switchstatement. Unlike the switch statement in which a branch is executed based upon on a value,
