Please Change Single to FirstOrDefault or First.Single returns a scalar value.So you can't use it like property

C#

var Query = (from t in context.userDetails where txtUserID.Text == t.UserID && SimpleHash.Encrypt_QueryString(txtPassword.Text ) == t.Password select new { t.Password }).FirstOrDefault();

Hope this helps
