C# 注册投掷'；重写成员'；

对于我的学校项目，我使用MVC项目附带的默认Account Controller register函数：

// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model){
    if (ModelState.IsValid){
        var user = new ApplicationUser(){UserName = model.UserName};
        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded){
            await SignInAsync(user, isPersistent: false);
            return RedirectToAction("Index", "Home");
        }
        else{
            AddErrors(result);
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

程序集只有在下注册时才被授予完全信任。如果程序集是私有程序集，则它是部分信任和透明的（）。由于您的程序集是

专用的

程序集，因此Dot Net CLR将忽略

[SecurityCritical]

因此，如果您计划继续保留

私有

程序集并以中等信任运行它，则无法重写或访问

您得到的异常的堆栈跟踪是什么？听起来你的类继承在某个地方有

private

应该是

public

@trailmax添加了stackTrace你有没有尝试创建一个新的项目来测试不同的框架版本？除非您更改了

UserManager.CreateAsync

方法，否则我不明白为什么会发生这种情况，除非您的信任级别有所不同或框架中存在缺陷。我没有更改任何默认函数，我想这是因为我不能改变我在网络空间上的信任级别。试着在你的IIS上设置完全信任：不完全跟随你。你能再解释一下吗？特别是为什么库存组件不会为GAC设置。或者这只是默认情况下未执行的操作？@Kiwi我列出了出现错误的原因，我的解决方案是：1-更改使用的程序集信任级别，或2-考虑其违反中等信任（用于重写）：）
