大家好,

Message: Object reference not set to an instance of an object.
Exception Type: System.NullReferenceException

我的流程总是报这个错误,我想获取更准确的错误提示
想用下面的方法尝试:

in that case you could place a Rethrow in the Catch and find out what the error is or also output exception.Source+" - "+exception.Message

我不知道该如何操作,能给我个例子吗?
