如何阻止NCalc写入控制台？

Question

我正在使用NCalc在控制台应用程序中进行数学评估。 它不断向控制台注入大量信息（特别是在执行Evaluate（）函数时）。 我找不到文档来阻止这种情况。 例如：

MyApp.exe Information: 0 : Expression added to cache: 18.855520754*45.5445916666667/100
MyApp.exe Information: 0 : Information: 0 : Expression retrieved from cache: 16*10
MyApp.exe Information: 0 : Expression added to cache: 18.855520754*45.5445916666667/100
MyApp.exe Information: 0 : Expression added to cache: 18.855520754*45.5445916666667/100
MyApp.exe Information: 0 : Expression added to cache: 45.5445916666667/6
MyApp.exe Information: 0 : Expression added to cache: 45.5445916666667/6

在哪里定义NCalc的输出详细程度？ 谢谢

这是我的App.config的样子（我删除了appSettings部分。此外，您在此处看到的日志记录部分适用于Quartz.NET）：

要在控制台中隐藏所有调试消息，请使用：

Expression.CacheEnabled = false;
