首先说明:如果没有进入调试模式的话,默认的调试窗口如下:
开始前的准备:
新建控制台程序DebugWindowDemo:
修改Program.cs 的代码为:

按F5,开始运行:
由于Debugger.Break();
所以当执行到这里的时候,Debugger会中断。
这个时候再看看调试窗口会发现多了几个窗口:
点击调试->窗口->并行任务,界面如下:
按下F5,继续运行:
双击查看相应等待的任务,就可以知道这个工作线程为什么等待了。
例如:
继续按F5,运行,你应该会看到:
总之关于当前运行的并行任务你都可以看的到。
关闭程序,重新F5,进入调试模式
选择调试->窗口->并行堆栈
可以看到:
其中蓝线代表当前正在执行的线程。
如果右键点击方法视图的S.C ,可以看到右键菜单如下:
点击切换方法视图
可以看到:
关闭程序,重新F5,进入调试模式
点击调试->窗口->线程:
可以看到:
当前控制台的所有线程都在这里。
在线程上点击右键可以冻结线程:
冻结线程也就是Pause线程,
冻结的线程可以被解冻,也就是Resume。
其他的窗口:
调试->窗口->模块:可以看到当前程序加载的所有模块。
调试->窗口->进程:
调试->窗口->反汇编:
调试->窗口->寄存器:
调试->窗口->调用堆栈:
调用堆栈窗口是比较常用的窗口:
上图表示先调用A方法,接着B方法,接着C方法。
也可以认为是C方法是B调用,而B方法是A调用的。
其他窗口比较常用,就不介绍了,是不是有一些你没用到的窗口呢?
