本文解析了在应用程序中遇到的'Cannot access a disposed object'错误，重点在于识别其常见原因——在依赖注入后尝试使用已释放的ThirdPartyDbContext。解决方案强调避免同步调用异步接口，同时推荐让依赖注入容器管理DbContext实例。

异常：

Cannot access a disposed object. A common cause of this error is disposing a context that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling Dispose() on the context, or wrapping the context in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances.
Object name: 'ThirdPartyDbContext'.

遇到这种情况一般是异步接口同步调用，查看调用接口处有没有加 await！
