[英]Ignoring unmapped members after ConvertUsing
this is my code : 这是我的代码:
public class UserProfile:Profile
{
public UserProfile()
{
CreateMap<UserViewModel, ApplicationUsers>().ConvertUsing<UserEncryptor>();
}
}
public class UserEncryptor : ITypeConverter<UserViewModel, ApplicationUsers>
{
private readonly IConfigurationRoot _configuration;
public UserEncryptor(IConfigurationRoot configuration)
{
_configuration = configuration;
}
public ApplicationUsers Convert(UserViewModel source, ApplicationUsers destination, ResolutionContext context)
{
if (context==null||source == null) return null;
var aes = new Common.EncryptionAes(_configuration[key: "Keys:AesKey"]);
return new ApplicationUsers
{
UserName = aes.EncryptAes(source.Username),
Email = aes.EncryptAes(source.Email),
PhoneNumber = aes.EncryptAes(source.MobileNumber),
User = new User
{
FirstName = aes.EncryptAes(source.FirstName),
LastName = aes.EncryptAes(source.LastName),
Gender = aes.EncryptAes(source.Gender.ToString()),
ProfileImage = aes.EncryptAes(source.ProfileImage.FileName)
}
};
}
}
Note that ApplicationUsers is inherited from IdentityUser Class. 请注意,ApplicationUsers继承自IdentityUser类。
When I tested this mapping,I got this error : 当我测试此映射时,出现此错误:
System.NullReferenceException: Object reference not set to an instance of an object.
System.NullReferenceException:对象引用未设置为对象的实例。
I know this error is for that some members are not ignored. 我知道此错误是因为某些成员未被忽略。 Something like this
像这样
CreateMap<UserViewModel ,ApplicationUsers >()
.ConvertUsing(converter=> new ApplicationUsers(){
Email = converter.Email,
....
});
will help me because by default ignore rest of the members but the problem is that if I want to use this kind of code, I cant encrypt my members because I don't access to DI configuration for profile.Because profile is parameter less. 会帮助我,因为默认情况下会忽略其余成员,但是问题是,如果我想使用这种代码,由于无法访问profile的DI配置,因此无法加密成员。因为profile的参数较少。
I need something similar to upper code that can implement in ITypeConverter functions. 我需要类似于可以在ITypeConverter函数中实现的上层代码的内容。
Anyone has any solution ? 任何人有什么解决方案吗?

that I asked my self,I got my answer : 我问自己,我得到了答案:
In my test I must define the profile like this : 在我的测试中,我必须像这样定义配置文件:
services.AddAutoMapper(typeof(UserProfile));
