在堆栈跟踪中输出现代C＃7.0+功能，看起来像C＃源代码生成它们而不是格式化。
对堆栈痕迹的高性能理解
.NET堆栈跟踪输出编译器转换方法；而不是源代码方法，这使它们在精神上解析并与源代码匹配。
当前的输出适用于C＃1.0；但是，由于C＃2.0（迭代器，仿制药）随着新功能的添加到.NET语言，并且在C＃7.1堆栈痕迹是深奥的（请参阅：当前堆栈痕迹的问题），因此变得越来越糟。
使错误日志提高生产力
以可理解的方式输出堆栈跟踪中的现代C＃7.0+功能，看起来像生成它们的C＃源代码。
用法
exception.Demystify()
或而不是环境.stacktrace
EnhancedStackTrace.Current()
将堆栈解析回呼叫的C＃源格式（并且是可检查的堆栈框架列表）
demystified异常上的呼叫.ToString()将产生类似于以下的字符串stacktrace（没有注释）：

当前堆栈跟踪的问题：
构造函数
不匹配代码，输出为
.ctor和.cctor参数
请勿指定预选赛
ref，out或in迭代器
无法确定过载
d__3.MoveNext() Iterator(int startAt)+MoveNext()linq
无法确定超负荷
Linq.Enumerable.SelectEnumerableIterator``2.MoveNext()而不是
Linq.Enumerable+SelectEnumerableIterator异步
无法确定过载，也无法确定诸如
async修饰符d__5``1.MoveNext() 而不是
async TaskProgram.MethodAsync(int value) 噪音！
--- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd(Task task) at System.Runtime.CompilerServices.TaskAwaiter.GetResult()Lambdas
主要是jibberish
<>c__DisplayClass2_0.<.ctor>b__0(Object state)建议他们声明的位置，但如果该方法有多个过载，则没有提示。本地功能
大多数是Jibberish
g__LocalFuncParam|10_0(String val, <>c__DisplayClass10_0& ) 通用参数
无法解决，仅指示数字
RunLambda(Func``1 lambda)而不是RunLambda(Funclambda) 价值元组
请勿匹配代码，将输出作为
ValueTuple``2 param而不是(string val, bool) param原始类型
不匹配代码，输出为
Int64，Boolean，String而不是long，bool，string返回类型
完全从方法签名跳过
基准
从存储库根运行基准：
dotnet run -p .test Ben.Demystifier .Benchmarks -c Release -f netcoreapp2.0 All
注意：我们只通过netcoreapp2.0开始，基准将用于所有配置的平台（如net462 。
