IronPDF 和 EvoPdf 是兩個用於創建、編輯和管理 PDF 文件的知名 .NET 庫。 每個都有獨特的優勢和功能,專為在 .NET 平台上工作的開發者量身打造。 本文將深入比較這兩個庫,重點介紹它們的功能、兼容性、許可證、支持等。
希望在閱讀本文後,您能夠識別最適合您 PDF 需求的函式庫,並且如果您想要探索更多 PDF 函式庫選項,能夠進行自己的比較。
IronPDF 是一個 .NET PDF 函式庫,可讓開發人員以程式方式創建、編輯和操作 PDF 文件。 以其易於使用、廣泛兼容.NET版本以及能夠將HTML、ASPX和圖像文件轉換為PDF的能力而著稱,同時保持對原始內容的高度忠實度。 IronPDF 的廣泛文件記錄、強大的客戶支持及豐富的功能集,使其成為尋求將 PDF 功能整合到 .NET 應用程序中的開發者的首選。
EvoPdf 是另一個 .NET 函式庫,專為 HTML 到 PDF 轉換及其他 PDF 操作任務而設計。 它提供對 HTML 標籤、CSS、JavaScript 及其他現代網頁技術的高級支援,從而能夠從網頁內容生成高品質的 PDF 文件。 EvoPdf 因其渲染能力和對網頁標準的廣泛支持而受到讚賞,這使得它成為專注於網頁轉PDF轉換的開發人員的寶貴工具。
IronPDF 提供廣泛的跨平台兼容性,使其成為適用於各種環境的多功能工具:
.NET 版本:
完全用 C# 編寫並支援 VB.NET 和 F#
.NET Core (8, 7, 6, 5, 和 3.1+)
作業系統和處理器:支援多種不同的作業系統和處理器,包括 Windows、Mac、Linux、x64、x86、ARM
如需有關 IronPDF 相容性的更多詳細資訊,請造訪IronPDF 相容性。
.NET 版本:
.NET Core(8、7、6 和 5)
IronPDF 和 EvoPdf 都提供強大的 PDF 操作功能,但開發人員應該考慮一些明顯的差異:
整合:無縫整合 ASP.NET和MVC應用程式。
如需完整的 IronPDF 功能列表,請造訪 IronPDF 功能。
以下是 IronPDF 和 EvoPdf 之間頂級功能的詳細比較,並附有具體的程式碼範例來展示它們的使用方法。

EvoPdf:對圖像和文字標記的支援有限,使用與其浮水印功能相同的工具。
IronPDF 提供詳細且靈活的方法來向 PDF 添加文字和圖像標籤,其蓋章工具易於使用,實現所需的代碼也很少。 EvoPdf 在將文字加蓋到您的 PDF 頁面之前需要進行更多設定。
DOCX 轉 PDF C#
IronPDF:
using IronPdf;
// Instantiate Renderer
DocxToPdfRenderer renderer = new DocxToPdfRenderer();
// Render from DOCX file
PdfDocument pdf = renderer.RenderDocxAsPdf("Modern-chronological-resume.docx");
// Save the PDF
pdf.SaveAs("pdfFromDocx.pdf");
using IronPdf;
// Instantiate Renderer
DocxToPdfRenderer renderer = new DocxToPdfRenderer();
// Render from DOCX file
PdfDocument pdf = renderer.RenderDocxAsPdf("Modern-chronological-resume.docx");
// Save the PDF
pdf.SaveAs("pdfFromDocx.pdf");
Imports IronPdf
' Instantiate Renderer
Private renderer As New DocxToPdfRenderer()
' Render from DOCX file
Private pdf As PdfDocument = renderer.RenderDocxAsPdf("Modern-chronological-resume.docx")
' Save the PDF
pdf.SaveAs("pdfFromDocx.pdf")
EvoPdf:您需要使用 Evo Work to PDF 轉換器庫來將 DOCX 文件轉換為 PDF 格式。
IronPDF 提供直觀的 API 進行 DOCX 到 PDF 的轉換,使處理不同文件類型更為容易。使用 EvoPdf 時,您需要確保已安裝 Evo Word to PDF 工具才能執行此任務。
