{"Object reference not set to an instance of an object."}

推荐答案

如果没有看到您的代码，我们无法告诉您任何事情。当您尝试访问 null 的对象属性时，通常会出现此错误。



检查这些更多细节与示例

为什么我会收到错误对象引用没有设置为对象的实例？ [ ^ ]

对象引用未设置为对象实例是什么意思？ [ ^ ]



对于FaultException，请查看本文

了解WCF中的异常处理，FaultExceptions和FaultContracts的初学者教程 [ ^ ]

We can't tell you anything without seeing your code. Usually you get this error when you're trying to access the property of object which is null.

Check these for more details with example(s)
Why do I get the error "Object reference not set to an instance of an object"?[^]
What does "Object reference not set to an instance of an object" mean?[^]

And for FaultException, check this article
