问题
I have in my database a column named Password of type Varbinary(150).
When I want to consult that database in the web api, for example:
var dbCon = ApplicationDbContext.Create(connectionStringUsers.ToString());
var users = dbCon.Users;
var list = users.ToList();
In the last line I have this error:
The 'PasswordHash' property on 'IdentityUser'4' could not be set to a 'System.Byte[]' value. You must set this property to a non-null value of type 'System.String'.
It know that if I change my schema from type Varbinary to Varchar it is going to work. But I cant change the schema. How can I hack this parse?
Thank you
UPDATE 1
Maybe something like this:
modelBuilder.Entity<ApplicationUser>().ToTable("MyUsers", "dbo").Property(p => p.PasswordHash).HasColumnType("varbinary");
But I get this error:
error 2019: Member Mapping specified is not valid. The type 'Edm.String[Nullable=True,DefaultValue=,MaxLength=Max,Unicode=True,FixedLength=False]' of member 'PasswordHash' in type 'OhmioWEBAPI.Models.ApplicationUser' is not compatible with 'SqlServer.varbinary[Nullable=True,DefaultValue=,MaxLength=8000,FixedLength=False]' of member 'Password' in type 'CodeFirstDatabaseSchema.ApplicationUser'.
