在 C# 中添加、提取和移除 Excel 中的圖片 新增圖片範例 若要將影像插入電子表格，請使用 InsertImage 方法。 它支援多種影像類型，例如 JPG/JPEG、BMP、PNG、GIF 和 TIFF。 您需要在工作表中指定圖像的左上角和右下角，以確定其尺寸。 尺寸是透過減去起始列索引和結束列索引以及行索引來計算的。 提取圖像範例 若要從選定的工作表中擷取影像，請造訪 Images 屬性，該屬性提供工作表中所有影像的清單。 透過此列表，您可以執行各種操作，例如匯出、調整大小、檢索位置以及獲取每張圖像的位元組資料。 值得注意的是，影像 ID 遵循奇數模式，以 1、3、5、7 等順序遞增。 移除影像範例 依照擷取影像的範例，您可以使用對應的索引號輕鬆刪除任何插入的影像。 只需將圖像的 ID 號碼傳遞給 RemoveImage 方法，即可將其從工作表中刪除。 探索如何使用IronXL處理 Excel 影像 相關文檔連結 在 Github 上查看 相關教程 相關操作指南 類文檔 下載 IronXL DLL 回報此頁面的問題 A PHP Error was encountered Severity: Notice Message: Undefined index: IronXl.Excel Filename: helpers/counter_helper.php Line Number: 85 Backtrace: File: /var/www/ironpdf.com/application/helpers/counter_helper.php Line: 85 Function: _error_handler File: /var/www/ironpdf.com/application/views/main/sections/ready_to_started_202509.php Line: 12 Function: getTotalDonwloadNumber File: /var/www/ironpdf.com/application/libraries/Render.php Line: 489 Function: view File: /var/www/ironpdf.com/application/controllers/Products/Examples.php Line: 44 Function: render_products_view File: /var/www/ironpdf.com/index.php Line: 292 Function: require_once A PHP Error was encountered Severity: Notice Message: Undefined index: IronXl.Excel Filename: helpers/counter_helper.php Line Number: 85 Backtrace: File: /var/www/ironpdf.com/application/helpers/counter_helper.php Line: 85 Function: _error_handler File: /var/www/ironpdf.com/application/views/main/sections/ready_to_started_202509.php Line: 19 Function: getTotalDonwloadNumber File: /var/www/ironpdf.com/application/libraries/Render.php Line: 489 Function: view File: /var/www/ironpdf.com/application/controllers/Products/Examples.php Line: 44 Function: render_products_view File: /var/www/ironpdf.com/index.php Line: 292 Function: require_once 準備好開始了嗎？ Nuget 下載 1,890,100 | 版本： 2026.3 剛剛發布 開始免費試用 免費 NuGet 下載 總下載量：1,890,100 查看許可證 A PHP Error was encountered Severity: Notice Message: Undefined index: IronXl.Excel Filename: helpers/counter_helper.php Line Number: 85 Backtrace: File: /var/www/ironpdf.com/application/helpers/counter_helper.php Line: 85 Function: _error_handler File: /var/www/ironpdf.com/application/views/main/sections/still_scrolling_202512.php Line: 17 Function: getTotalDonwloadNumber File: /var/www/ironpdf.com/application/views/products/examples/index.php Line: 270 Function: view File: /var/www/ironpdf.com/application/libraries/Render.php Line: 88 Function: view File: /var/www/ironpdf.com/application/libraries/Render.php Line: 552 Function: view File: /var/www/ironpdf.com/application/controllers/Products/Examples.php Line: 44 Function: render_products_view File: /var/www/ironpdf.com/index.php Line: 292 Function: require_once A PHP Error was encountered Severity: Notice Message: Undefined index: IronXl.Excel Filename: helpers/counter_helper.php Line Number: 85 Backtrace: File: /var/www/ironpdf.com/application/helpers/counter_helper.php Line: 85 Function: _error_handler File: /var/www/ironpdf.com/application/views/main/sections/still_scrolling_202512.php Line: 24 Function: getTotalDonwloadNumber File: /var/www/ironpdf.com/application/views/products/examples/index.php Line: 270 Function: view File: /var/www/ironpdf.com/application/libraries/Render.php Line: 88 Function: view File: /var/www/ironpdf.com/application/libraries/Render.php Line: 552 Function: view File: /var/www/ironpdf.com/application/controllers/Products/Examples.php Line: 44 Function: render_products_view File: /var/www/ironpdf.com/index.php Line: 292 Function: require_once 還在捲動嗎？ 想要快速證明？ PM > Install-Package IronXl.Excel 執行範例 觀看您的資料變成試算表。 免費 NuGet 下載 總下載量：1,890,100 查看許可證
