标识用户数据未更新

Question

我的自定义身份用户没有更新，但它也没有给出任何错误。我要粘贴整个控制器代码，因为我认为这很重要。因为我用的是AspNetCore。身份，我不能用asp.net。身份。当我试图在另一个控制器中执行Edit操作时，我使用AspNet。标识并写入如下内容:

ApplicationUser appUser = new ApplicationUser();
appUser = UserManager.FindByEmail(email);

UserManager给出错误https://learn.microsoft.com/en-us/dotnet/csharp/misc/cs0305?f1url=%3FappId%3Droslyn%26k%3Dk(CS0305)

我发现值得一提的是，我手动设置数据库中的FirstName和姓氏，提交按钮后，它已更改为NULL。

Answer 1

我通过调试找到了答案。在评论部分@Adleri问_userManager.FindByEmailAsync(email)返回什么对象，所以我检查了它。它返回ApplicationUser所以我更改了

var currentUser = await _userManager.FindByEmailAsync(model.Email);

ApplicationUser currentUser = new ApplicationUser();
currentUser = await _userManager.FindByEmailAsync(model.Email);

然后我发现currentUser字段是空的，所以我改变了

model.FirstName = currentUser.FirstName;
model.Surname = currentUser.Surname;

currentUser.FirstName = model.FirstName;
currentUser.Surname = model.Surname;

简单地交换位置，它现在工作了。
