无法加载文件或程序集

标签： c# .net-3.5 devexpress filenotfoundexception

我有一个域对象的集合。它被称为company.xpo.domain（由最初命名该项目的承包商命名，它们与我们相比更长 - 我们拥有该软件）。我对命名空间进行了全局重命名为xpo.domain，并将设计器中的默认命名空间更改为xpo.domain。

我也在视觉工作室找到了关于“公司”整个解决方案的发现，但没有找到任何结果。

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”，它接受用户名和密码，检查db的名称/密码，如果没有找到则返回null。

在这个静态方法中，它会为company.xpo.domain程序集抛出一个FileNotFoundException。这让我感到困惑，因为抛出异常的代码存在于它正在寻找的程序集中（但它正在查找程序集的先前名称）。

修改 这是堆栈跟踪。为了安全起见，我刚刚对软件名称和程序集名称进行了重命名。

如果有帮助，调用堆栈就在这里。似乎看起来devexpress.data.utils抛出错误，但我无法控制该类（如果它实际上是该程序集的问题）。

注意：我也使用DevExpress创建了一个案例，以防万一。我完全被难过了。

我肯定需要看到堆栈跟踪和/或代码才能确实知道，但听起来我可能会在程序集中有一些循环引用，其中一个引用旧的程序集。但这完全只是在黑暗中刺伤。

答案 1 :(得分：1)

如果可以，如果适用，我会检查与您可能拥有的任何类型化数据集关联的代码;我在Typed DataSet类中重命名命名空间时遇到了问题。我必须进去，不得不手动“搜索和替换”。

同样，这对你来说可能并不适合。

另一种可能性：
您的GAC中是否有可能通过名称引用旧程序集？
