ASP.NET网站没有办法删除/删除注册用户,因此在我的测试项目(WatiN with NUnit)中,我试图通过调用Membership.DeleteUser()来删除测试用户帐户.然后我意识到我不能使用它,因为我无法在我的NUnit项目(在visual studio中)中使用web.config配置成员资格提供程序.
如何在不使用ASP.NET的情况下配置成员资格提供程序?

[---]Git中的注释是否只能% tool=opendiff %在我的使用中使用一次.gitconfig?
我在C#中开发一个软件,它通过Wrapper使用C++ .dll文件中的静态函数.
问题是这些函数中的一些是缓慢且不稳定的,所以为了解决这个问题,我创建了一个执行它们的Thread.但是,当我从主线程中止该线程时,程序不允许我再次使用这些函数,即使我每次调用函数时都定义了一个新的线程实例.
有什么办法可以解决这个问题吗?
提前致谢.
