Question

我希望编辑UserManager类添加一些方法，例如ChangeEmailAsync（克隆ChangePasswordAsync）我是C# and .NET的新手，因为我以前在java工作，我是阅读微软网站的启动并练习一些表格。

我看到一行代码：

IdentityResult result = await UserManager.ChangePasswordAsync(User.Identity.GetUserId(), model.OldPassword, model.NewPassword);

我希望看到UserManager中的代码复制ChangePassword并创建ChangeEmail，并了解创建某些方法的过程（更改其他字段等）

我使用 F12 导航到UserManager，我看到它的界面（或看起来像java界面）

I can implement this? And I can see the code of the methods.

非常感谢你的帮助，对不起我的英语

您无法直接向此类添加新方法，因为它来自另一个程序集。我可以看到你为什么称它为接口，但从另一个程序集导航到一个类实际上只显示了类的构造函数，属性和公共方法的不同签名。你无法改变这些。

要更改用户的属性，您应该在UserManager上使用UpdateAsync(TUser user)方法，也许这样（在您的控制器中）：

    [HttpPost]
    public async Task<ActionResult> ChangeEmail(string newEmail)
    {
        var user = await UserManager.FindByNameAsync(User.Identity.Name);
        user.Email = newEmail;
        UserManager.UpdateAsync(user);
        return View();
    }
