Asp.net Identity UserManager 错误：用户名为空

Question

UserManager CreateAsyncy 报错：UserName 不能为空或 null。

下面是我的代码sn-p：

    var contractor = new Contractor()
                {
                    UserName = contractorModel.UserName,
                    Email = contractorModel.Email,
                    EmailConfirmed = true,
                    SecurityStamp = Guid.NewGuid().ToString()


                };
               var result =  await UserManager.CreateAsync(contractor,"Passw0rd!");

Answer 1

我通过 UserName =contractorModel.Email 修复了它；
