Dynamic CRM插件中记录日志的方式有多种 通常情况下分为ITracingService记录、单独日志表插入记录、文本记录三种。之前整理过ITracingService记录的方式，但这种记录有限制，只有存在异常时才会在插件跟踪日志中查到，异常报错时排查问题到可以，但插件详细的日志记录查看就不很方便，并且插件跟踪日志中记录到最上层的插件，直接通过插件名查询不方便。 单独日志表的方式，也很简单，自定义一个日志表，在插件中调用封装好的日志插入方法即可，但这个存在一个致命的问题，像是普通的信息记录没问题，若存在异常，插入操作会回滚，所以无法通过这种记录排查异常。 第三种文本记录，需要引用第三方组件，比如Nlog或者Lognet4，我使用的NlogNlog日志记录单例类早就有封装，可以在插件程序集中直接引用过来，最核心的地方就是Nlog的config文件，在插件程序集中不需要单独放置一份NLog.config，只需要在CRM的应用服务的Dynamics 365\CRMWeb\bin文件夹中放置好即可，并且保证CRMWeb里bin中的NLog.dll与插件程序集中引用的版本一致提示：1.通常服务器上CRMWeb路径为：C:\Program Files\Dynamics 365\CRMWeb\bin2.NLog.config中具体指明一下文件存放的路径
