无法加载文件或程序集“ xxx.Data”，因为其他进程正在使用该文件，所以该进程无法访问该文件

本文介绍了无法加载文件或程序集“ xxx.Data”，因为其他进程正在使用该文件，所以该进程无法访问该文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

从今天开始，我在一个已经工作了几个月并且一直工作的项目中遇到了这个错误。

I have this error since today in a project which I have worked for months and has always worked.

我尝试清洁解决方案并进行重建，并且构建过程完美。 我尝试重新启动VS和PC，但没有任何效果。

I tried cleaning the solution and rebuild, and building works perfect. I tried restarting VS and the PC and nothing works.

所以问题不在代码中

无法加载文件或程序集 xxx.Data或其依赖项之一。该进程无法访问该文件，因为该文件正在被另一个进程使用。 （来自HRESULT的异常：0x80070020）

Could not load file or assembly 'xxx.Data' or one of its dependencies. The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)

说明：在执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪，以获取有关错误及其在代码中起源的更多信息。

程序集加载跟踪：以下信息有助于确定为什么程序集' xxx.Data'无法加载。

推荐答案

如消息所示，该文件正在使用中。这不是Visual Studio或.NET，而是操作系统。

As the message says, the file is in use. This isn't a Visual Studio or .NET thing, it is an operating system thing.

另一个程序正在使用该文件，该文件可以是病毒扫描程序，另一个应用程序

Another program is using the file, that can be a virus scanner, another application that is running, or even Visual Studio (sometimes the debugger keeps a file locked).

当您尝试删除或重命名时，Windows会告诉您是由哪个程序负责锁定的程序文件。我建议这样做，以查看哪个程序锁定了您的文件。

Windows tells you what program is responsible for the lock when you try to delete or rename the file. I would recommend to do that to see what program is locking your file.
