C# 无法加载文件或程序集

我有一个域对象的集合。它被称为company.xpo.domain（它是由最初命名该项目的承包商命名的，他们与我们在一起的时间更长——我们拥有该软件）。我将名称空间全局重命名为xpo.domain，并将设计器中的默认名称空间更改为xpo.domain

我还在VisualStudio中找到了“公司”的整个解决方案，但什么也没找到

我的问题是这样的：

在程序集中有一个用户对象，它有一个静态方法“Login”，该方法接受用户名和密码，检查数据库中的名称/密码，如果没有找到任何内容，则返回null

在该静态方法中，它为company.xpo.domain程序集抛出FileNotFoundException。这让我感到困惑，因为抛出异常的代码存在于它要查找的程序集中（但它要查找的是以前的程序集名称）

编辑 这是堆栈跟踪。为了安全起见，我刚刚对软件名和程序集名进行了重命名

调用堆栈（如果有帮助的话）就在这里。似乎devexpress.data.utils抛出了错误，但我无法控制该类（如果该程序集确实存在问题）

注意：我也用DevExpress创建了一个案例，以防万一。我完全被难住了。

我肯定需要查看堆栈跟踪和/或代码才能真正确定，但在我看来，程序集中可能存在某种循环引用，其中一个引用了旧程序集。但这完全只是一种暗中操作。

如果可以，如果适用，我会检查与您可能拥有的任何类型数据集相关的代码；我在重命名类型化数据集类中的名称空间时遇到问题。我不得不进去，不得不手动进行“搜索和替换”

再说一次，这对你来说可能并不重要
