推荐答案

添加最终规则，将日志写入黑洞".将其添加为第一条规则.使用enabled属性将其关闭/打开.

Add a final rule that writes the logs to a "blackhole". Add this as the first rule. Turn it off/on with the enabled attribute.

例如要禁用信息"级别，请将其添加为<rules>的第一条规则:

e.g. To disable the "info" level, add this as first rule of <rules>:

<logger levels="Info" name="*" writeTo="blackHole" final="true" enabled="true" />

，黑洞目标为<targets>

<target name="blackHole" xsi:type="Null" />
