我试图执行这个测试方法，但它抛出了一个异常。当我逐步执行代码以尝试隔离异常时，它导致我：

public override MembershipUserCollection FindUsersByName(string usernameToMatch, int pageIndex, int pageSize, out int totalRecords)

如下所示的测试方法。此处抛出异常并显示以下消息

"Item has already been added. Key in dictionary: 'john'  Key being added: 'john'".

我不知道从这里去哪里。有人可以指出我正确的方向吗？另外我的测试方法还在工作中，所以如果你看到任何错误，除非错误直接导致异常被抛出，请忽略它们。

您不能在 MembershipUserCollection 中存储多个同名用户。它按用户名编制索引，因此可以防止您为每个名称添加多个 MembershipUser。

问题出在 GetUserFromModel() 方法中。它使用搜索名称作为用户的名称，因为它正在查找 2 个名称中包含“john”的用户，它正在创建 2 个用户名为“john”的用户。它可能应该使用他们的原始用户名，而不是用于搜索的部分用户名。

如果您的任何成员资格提供程序对象是静态的或共享引用，并且您在多个测试中添加“john”用户，那么您有一个竞争条件，因为测试是并行/多线程执行的。要解决此问题，您必须配置一个测试设置/拆卸，以清除每个测试的数据结构，并按顺序执行它们，或者将这些对象包装在一个自定义对象中，该对象已编程到您可以模拟的接口。
