오류가 라인에 이유를 파악하지 못할 붙 잡혔다 :일반 오류는 GDI에서 발생 + ExternalException은
for (int x = 0; x < myList.Count(); x++)
x++은 녹색으로 색칠한다.
나는 백그라운드 워커를 사용하고 있기 때문에 배경 작업자가 없기 전에이 코드를 다른 형식으로 사용했습니다. 이제 다른 양식에서 클릭 버튼 이벤트를 사용하여 show()이 양식을 작성하고 progressBar1을 사용하여 backgroundowrker 작업의 진행 상황을 표시하고 싶습니다.
지금은이 for 루프를 사용해보고 catch 지점으로 가서 오류를 보였습니다. 전체 예외 메시지는 다음과 같습니다
at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)
at System.Drawing.Image.Save(String filename, ImageFormat format)
at mws.Animation_Radar_Preview.backGroundWorker1_DoWork(Object sender, DoWorkEventArgs e) in D:\C-Sharp\Download File\Downloading-File-Project-Version-012\Downloading File\Animation_Radar_Preview.cs:line 163
gifImages isnt null.
이이 양식의 전체 코드입니다 : 나는이 같은 코드는 이전 일을 말한다 특히, 잘못 무슨 일이 일어나고 있는지 전혀 모르겠어요

Save() 호출 후 gifImages.Dispose()를 잊어 버렸습니다. 파일에 대한 잠금을 해제하는 데 필요합니다. –
