让您的应用将 Microsoft Word 文件转换为 PDF，使文档更易于访问，并且用户可以更轻松地跨设备共享。

Word to PDF functionality within a PDF component refers to the ability to convert Microsoft Word documents (.docx) into Portable Document Format (PDF) files directly within your software application. This embedded conversion capability offers developers several advantages. It streamlines the document handling process by eliminating the need for external tools or libraries. It also ensures compatibility, as the conversion occurs entirely within your program. This can be particularly useful for applications where users interact with both Word documents and PDFs.

Several .NET PDF components allow you to convert Word files to PDF including:

  • DevExpress PDF Document API (part of DevExpress Office File API) streamlines Word to PDF conversion within your .NET applications.
  • Telerik UI PDF for WinForms (part of Telerik UI for WinForms) offers a comprehensive library for generating PDFs, including conversion from Word documents.
  • ImageGear for .NET by Accusoft empowers developers with a robust toolkit for image and document processing, including Word to PDF conversion.

通过将 PDF 保存到流来减少内存使用量

4月 2, 2024
让您的 .NET 8 应用拥有将 PDF 文件直接保存到流中的功能，从而提高数据处理速度并减少内存占用。

Saving PDFs to a stream offers increased flexibility and efficiency in the management and transmission of PDF documents. This approach of saving PDF files segments the file's content into an organized and compressed sequence of bytes (the stream), representing the content and structure of the document. This method allows for faster initial loading by prioritizing text content, enables partial downloads for quicker access over slow connections, and reduces memory usage by loading only the currently viewed section. This allows for real-time processing, manipulation, and direct transmission of data without the intermediary step of storing it on a disk. Employing streams is particularly advantageous in scenarios requiring memory efficiency, dynamic content generation, seamless network distribution, or integration within larger systems where direct file handling is cumbersome or inefficient.

Several .NET 8 PDF components allow you to save PDFs to a stream, including:

  • DevExpress PDF Document API (part of DevExpress Office File API) is a cross-platform API library that can be used to manage PDF files and for saving PDFs as a stream in .NET 8 applications.
  • ComponentOne Studio WinForms PDF (part of ComponentOne Studio WinForms) by MESCIUS enables developers to create .NET 8 WinForms applications that can be used to create, manipulate, and export PDF documents which can be saved in a streamed format.
  • Telerik UI PDF for WinForms (part of Telerik UI for WinForms) is a flexible, high-performing WinForms library that supports .NET 8. It enables you to generate and edit PDFs as well as to save them to streams for optimized loading and memory usage.
  • IronPDF for .NET by Iron Software equips developers with a user-friendly C# library to generate, edit, and manage PDFs. It supports .NET 8 and allows you to save PDF files as a stream for efficient document management and web integration.
