在那之后我没有收到任何错误

是否有更多关于错误的细节？更多关于消息？堆栈跟踪？内部异常？Detalles de la Exception:Microsoft.CSharp.RuntimeBinder.RuntimeBinderException:No se puede realizar enlace en tiempo de ejección en una referencea null你能把它翻译成英文吗？堆栈溢出是英文的h网站，很难用另一种语言帮助您。Microsoft.CSharp.RuntimeBinder.RuntimeBinderException:无法在空引用中执行时建立连接，哪一行会引发错误？
