无法在LINQ中将类型'string'隐式转换为'System.Data.Linq.Binary

Question

I've hashed the password and then I'll insert it to the database but the problem here is that each time I try to do this query this occurs

Cannot implicitly convert type 'string' to 'System.Data.Linq.Binary'

in my table in the database accnt_pass is Binary(50), here's my code

//Instantiate a new Hasher Object
var hasher = new Hasher();

hasher.SaltSize = 16;

//Encrypts The password
var encryptedPassword = hasher.Encrypt(txtPass.Text);

Account newUser = new Account();

newUser.accnt_User = txtUser.Text;
newUser.accnt_Position = txtPosition.Text;
newUser.accnt_Pass = encryptedPassword; 

and I am using Encrypto for hashing,

Answer 1

You need to convert the string encryptedPassword to a byte array if your sql column is of binary type. So instead of the line

newUser.accnt_Pass = encryptedPassword;

put

System.Text.UTF8Encoding encoding=new System.Text.UTF8Encoding();
newUser.accnt_Pass = new System.Data.Linq.Binary(encoding.GetBytes(encryptedPassword));
