업데이트 할 때 오류가 발생했습니다. 오류 :이 오류를 해결하는 방법을 알아낼 수없는 하나 개 이상의 필수 매개 변수

Question

주어진 값 없음 :

Exception Details: System.Data.OleDb.OleDbException: No value given for one or 
more required parameters. 

나는 사용자의 정보를 업데이트 할 때마다 나는이 오류가 발생합니다. 나는 코드에서 빠진 것이 무엇인지 알아 내려고 해법을 찾고 있었다. 나는 이와 비슷한 질문을 발견했으나 어떤 것이 제거되어야하는지 잘 모르기 때문에 종류가 다릅니다.

Answer 1

UpdateCommand에서 매개 변수의 순서가 UpdateParameters에서와 동일해야합니다

여기에 코드입니다. 또한 [Student_MobilePhoneCountryCode]이 UpdateParameter 목록에서 누락되어 있는지 확인하십시오.
