私は新しいプログラマーで、画面上の特定の座標をクリックして画面から画像を検索し、見つけたらクリックするプログラムをc#で作成しようとしています。プログラムは正常に動作していますが、30 ～ 40 分後にクラッシュします。クラッシュするとウィンドウがポップアップします - アプリケーションで未処理の例外が発生しました....

新しいビットマップ、グラフィックスを作成すると、内部 GDI+ 関数呼び出しが発生します。これらの関数はすべてエラーになる可能性があり、エラーは .NET 例外に変換されます (残念ながら、追加のパラメーター名や情報などはありません)。このため、一部のエラーは理解するのが非常に難しい場合があります。

ハンドル リークとメモリ リークが原因で、いくつかの問題が発生する可能性があります (GDI+ の場合)。たとえば、非常に大きなビットマップを多数作成すると、管理されていない領域に多数の連続したブロックが割り当てられます。GC はメモリ プレッシャを認識せず、クリーンアップを試みません。たとえば、100 回の呼び出しの後に十分な大きさの Width と Height を渡すと、メモリ不足に気づき、ArgumentException をスローして幅と高さが大きすぎると不平を言う可能性があります。

まず、ビットマップが必要ない場合は廃棄することを検討してください。グラフィックスも忘れずに処分してください。

問題が解決しない場合は、お知らせください。
