StackTrace 类
表示一个堆栈跟踪,它是一个或多个堆栈帧的有序集合。
**命名空间:**System.Diagnostics
**程序集:**mscorlib(在 mscorlib.dll 中)

备注
在调试版本配置下,StackTrace 提供的信息量最多。默认情况下,调试版本包含调试符号,而发布版本不包含。调试符号包含在构造 StackFrame 和 StackTrace 对象时使用的文件、方法名、行号和列信息这些数据中的大部分。
由于优化期间发生代码转换,StackTrace 报告的方法调用可能没有预期的多。
示例
下面的控制台应用程序演示如何创建简单的 StackTrace,以及如何循环访问它的帧获取调试和诊断信息。
