我如何获得用户名，我使用ASP.. NET Core MVC和Identity

只需注入一个IHttpContextAccessor到你的类中(作为一个构造函数依赖)，然后你可以从上下文中的User对象中获得名称:

private IHttpContextAccessor context;
public SomeRepo(IHttpContextAccessor context)
{
    this.context = context;
}
//in your method
var userName = this.context.HttpContext.User.Identity.Name;

由于您正在使用身份框架，如果您需要当前用户除了其名称之外的其他数据，您可以注入UserManager<ApplicationUser>并使用GetUserAsync(HttpContext.User)

等任何方法检索整个ApplicationUser对象。
