이것은 일반적으로 내부 스택 트레이스 이어진다 iDispatch은 내 프로그램의 이름입니다.
이제 여러 가지 방법을 사용하여 여러 테이블에 삽입 할지라도이 문제는 모든 메서드에서 임의로 발생합니다. 레코드가 삽입 된의

문제는, 100의, 때로는 1000 년대 이후 발생 : 일반적으로 삽입하는 방법은 다음과 같이 보인다.
테이블에 삽입하는 것이 괜찮은 것 (Navicat Lite 사용)과 오류가 잘 보이는 것 (즉, 디버거에서 모든 데이터가 올바른지 확인할 수 있습니다.).
나는 Windows 용 윈도우 (ADO.NET SQLite는 2.0 데이터 공급자), 모노에서 실행되는 동일한 코드를 가지고 있고, 모노는 MonoTouch (버전 2.4.2에 ... 맥북 프로에서 실행, 출시 ID : 20402005, Git revision : b7eeb779e1134c204f22d9fd5b6ebec4d758f60d, 빌드 날짜 : 2011-04-22 22 : 48 : 43 + 0000) 이 오류가 표시 되나요?도움이 될 것입니다.
은 BTW : 솔루션을 온라인으로 검색 한 후, 나는 다음과 같은 '지속 저널'명령을 추가하지만, 아무런 효과도 없었다 :

감사합니다!
foreach 루프에 도달하기 전에 명령 개체의 Parameters 컬렉션에 매개 변수를 추가 한 다음 루프 내의 매개 변수 값을 할당 할 수 있습니다. 예 : 'command.Parameters.Add ("@ ID", SqlDbType.Int); '루프 외부; 그리고 루프 안에서 :'command.Parameters [ "@ ID"]. 값 = 고객 ID;'http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparametercollection.addwithvalue.aspx – Tim
foreach 절에서 새로 추가하기 전에 매개 변수를 지워야합니다.나는 당신이 매개 변수의 수의 한계를 쳤다고 생각한다 –
