有没有人曾经有过在SessionModSvcContractClient注销函数抛出异常的一个问题:当我试图LogoutAsync和关闭方法,他们的Epicor 10.1.5 SessionModSvcContractClient注销
Object reference not set to an instance of an object.
:附加信息工作得很好。 任何人可以帮助我弄清楚为什么会发生的事情或3
之间的差别基本上,我试图使用从WCF引导

请包括您的代码,这是一个标准的NullReferenceException,并有多种原因。请参阅:http://stackoverflow.com/questions/4660142/what-is-a-nullreferenceexception-and-how-do-i-fix-it –
我基本上尝试从WCF示例代码 – yahyazini
