O aplicativo de console a seguir demonstra como criar um StackTrace simples e iterar por meio de seus quadros para obter informações de depuração e diagnóstico.The following console application demonstrates how to create a simple StackTrace and iterate through its frames to obtain debugging and diagnostic information.

Comentários

StackTraceas informações serão mais informativas com as configurações de compilação de depuração.StackTrace information will be most informative with Debug build configurations. Por padrão, as compilações de depuração incluem símbolos de depuração, enquanto as compilações de versão não.By default, Debug builds include debug symbols, while Release builds do not. Os símbolos de depuração contêm a maior parte do arquivo, o nome do método, o número de linha e as StackFrame informações StackTrace de coluna usadas na construção e nos objetos.The debug symbols contain most of the file, method name, line number, and column information used in constructing StackFrame and StackTrace objects.

StackTracepode não relatar tantas chamadas de método quanto esperado, devido a transformações de código que ocorrem durante a otimização.StackTrace might not report as many method calls as expected, due to code transformations that occur during optimization.
