Unity は PPT をロードして表示します

予防：

1. コードは Aspose.Slides System.Drawing I18N シリーズの dll を使用する必要があり、プロジェクト設定は net4.0 です。

2. Unity バージョンの要件があり、System.Drawing.dll は現在の Unity バージョンから取得する必要があります。

3. エクスポート後に正常にロードされない場合があります。Unity の新しいバージョン (2018 など) のインストール ディレクトリ Editor\Data\MonoBleedingEdge\lib\mono\unityjit で I18N.dll および I18N.West.dll ファイルを見つけて、パッケージ化された XX_Data/Managedフォルダーにコピーして貼り付けます
