Answer 1

무슨 일이 있었는지 알아 디버거를 사용합니다. 당신의 createuser가 방법이 줄 앞에

if(password == null) 
    throw new Exception("Password is null here, I get it, now I'll try to find where is wrong!"); 

:

ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, password, true); 

그리고 다시 실행, 아무것도 있는지 그 방법을 모르는 경우, 다음이 줄을 추가

일어난다.

Answer 2

짐작할 수는 있겠지만 password 변수가 아니라는 사실은 내기를 전달하지 않거나 null 값을 전달하려는 passwordAnswer을 인코딩하려고하기 때문입니다.이 기능을 사용하고 있지 않을 것입니다. 이것은 MS가 더 이상 사용하지 않는 암호를 복구하기에 시대에 뒤 떨어지고 위험한 방법입니다.

이 줄 CreateUser에 :

sqlCommand.Parameters.Add("@passwordAnswer", SqlDbType.NVarChar, 255).Value = EncodePassword(passwordAnswer); \\THIS LINE IS PROBABLY THE PROBLEM 

대신을 시도,하지만 당신은 확실히이 기능을 사용하지 않을 경우에만 :

sqlCommand.Parameters.Add("@passwordAnswer", SqlDbType.NVarChar, 255).Value = passwordAnswer; 

당신은 디버깅에 쉽게이를 확인 할 수 있어야한다.
