asp.net-mvc - 如何在 .NET Core 中更改 SQL 数据库中的 FirstName 属性？

Question

我已经成功验证了我的应用程序，但我似乎唯一不能做的就是更改我所做的用户属性。

public async Task<IActionResult> OnPostAsync()
{
    var user = await _userManager.GetUserAsync(User); 

    if (user == null)
    {
        return NotFound($"Unable to load user with ID '{_userManager.GetUserId(User)}'.");
    }

    if (!ModelState.IsValid)
    {
        LoadAsync(user);
        return Page(); 
    }

    var phonenumber = await _userManager.GetPhoneNumberAsync(user);
        
    if (Input.PhoneNumber != phonenumber)
    {
        var setPhoneNumber = await _userManager.SetPhoneNumberAsync(user, Input.PhoneNumber);
    }

    user.FirstName = Input.FirstName; 

    return RedirectToPage(); 
}

如果有人知道如何更改 FirstName属性(property)，谢谢。

I have successfully authenticated my app, but the only thing that I can't seem to do is change the user properties that I have made.

您可以尝试调用 UserManager<TUser>.UpdateAsync(TUser) method更新指定的用户，如下所示。

//set FirstName of current user
user.FirstName = Input.FirstName;

//update the specified user
await _userManager.UpdateAsync(user);
