刚刚装好的虚拟机突然不能上网了,报错很诡异,具体报错如下: /etc/init.d/network restart Restarting network (via systemctl): Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe&quo
Least significant byte (LSB) Most significant byte (MSB) Big-endian machines store the most-significant byte at the lowest-numbered address, with the other bytes following in decreasing order of significance. Little-endian machines store multi-byte n

ASP.NET Core的路由是通过一个类型为RouterMiddleware的中间件来实现的.如果我们将最终处理HTTP请求的组件称为HttpHandler,那么RouterMiddleware中间件的意义在于实现请求路径与对应HttpHandler之间的映射关系.对于传递给RouterMiddleware中间件的每一个请求,它会通过分析请求URL的模式并选择并提取对应的HttpHandler来处理该请求.除此之外,请求的URL还会携带相应参数,该中间件在进行路由解析过程中还会根据生成相应的路
EntityFramework 一对一关系映射有很多种,比如主键作为关联,配置比较简单,示例代码: public class Teacher { public int Id { get; set; } public string Name { get; set; } public virtual Student Student { get; set; } } public class Student { public int Id { get; set; } public string Name
