我很抱歉问这个问题,但我不知道发生异常的地方.这是堆栈跟踪：

One or more errors occurred.

我认为抛出的异常是这样的：

Object reference not set to an instance of an object.
       at MyCompany.Dispositivos.Plugins.TICAnKorr.VisorTICAnKorrMini.MensajeEstado()

什么是真正的例外？

如果这不是提出这个问题的正确位置,请告诉我并删除它.

我不是问对象引用没有设置为对象实例的含义是什么.我知道,我问这是否是使得任务抛出System.Threading.Tasks.Task的异常. ThrowIfExceptional.
