你忘了告诉我们_what_错误时抛出。运行时值是什么时候抛出的。 – David 2012-07-10 10:06:25
当我用某个用户名,密码登录时,它在第8行出现throwsx错误。 – NoviceToDotNet 2012-07-10 10:07:37
错误非常明显,“对象引用未设置为对象的实例”。由于它发生在第98行,因此'_userDetails'或'Rows'都是'null'。我的猜测是'_userDetails'是'null'。在这种情况下,您的'Data.GetSQLQueryResults()'方法被破坏,因为返回'null'是一个坏主意。无论哪种方式,这不是你的问题所在。您需要修复该功能(可能还有很多其他代码)来报告遇到的问题,以便确定哪些问题。 – David 2012-07-10 10:10:07
