用高效的 LINQ 投影优化数据访问

AutoMapper 通过约定和验证改进了对象映射,从而减少了样板代码并加快了 .NET 开发。

AutoMapper by Lucky Penny Software is a convention-based object-to-object mapping library designed for Microsoft .NET developers. It improves the process of transforming data between objects, particularly when mapping complex domain models to simpler Data Transfer Objects (DTOs), using intelligent conventions and configuration options to minimize manual coding.

By eliminating repetitive boilerplate mapping code, AutoMapper helps developers build cleaner, more maintainable applications. It enforces consistent naming conventions, validates mappings at runtime, and optimizes LINQ projections for efficient data querying. This makes it especially valuable in layered architectures, API development, and enterprise applications where data transformation is frequent and complex. From startups to large organizations, teams use AutoMapper to reduce errors, accelerate development cycles, and focus on delivering business value rather than managing tedious object-mapping logic.

AutoMapper is licensed on an annual subscription basis per development team, with Standard (1–10 developers), Professional (11–50 developers), and Enterprise (unlimited developers) tiers. See our AutoMapper licensing page for full details.

启用从流安全加载 PDF

直接从流加载和渲染 PDF,实现跨云端、容器和数据库驱动 ASP.NET 应用的安全、无文件浏览。

Opening PDFs directly from streams in ASP.NET PDF Viewer components refers to the ability to load and render PDF documents from a .NET Stream object rather than from a physical file stored on the server. This means the PDF content can be retrieved dynamically from sources such as databases, cloud storage, web APIs, or generated in memory at runtime, and then passed directly to the viewer for display. By working with streams, applications can avoid temporary file storage, improve security by reducing file system exposure, and better support modern deployment scenarios such as containerized or cloud-based environments where local storage may be limited or transient.

Several ASP.NET Core PDF viewer components offer open PDFs from stream functionality including:

DevExpress Office File API 添加对 PowerPoint 表格的支持,使应用程序能够在演示文件中读取、写入和修改表格数据。

DevExpress Office File API is a robust library designed to simplify the creation, editing, and processing of popular office document formats, including Word, Excel, PowerPoint, and PDF. It allows developers to integrate advanced document management features into their applications without relying on external software like Microsoft Office. Key features include document generation, data import/export and template customization. The API supports advanced formatting, encryption, and digital signatures, ensuring secure and professional-grade output.

The DevExpress Office File API now includes full support for PowerPoint tables, allowing applications to upload and save presentations that contain tabular data and interact with that data through code. Developers can read existing tables, modify their structure and content, remove tables that are no longer needed, or create entirely new tables from scratch. This addition makes it easier to automate report generation, update presentation data, and integrate PowerPoint files into document processing workflows where tables play a central role.

DevExpress Office File API is licensed per developer and is available as a Perpetual License with a 12 month support and maintenance subscription. See our DevExpress Office File API licensing page for full details.

DevExpress Office File API is available individually or as part of DevExpress Universal.

用仪表清晰可视化数据

带有仪表控件的 .NET WPF UI 套件显示实时测量和运行状态,一目了然。

Gauge controls in .NET WPF UI suites are specialized visual components designed to present quantitative data in an intuitive, instrument-style format, similar to speedometers, thermometers, or dial indicators. They are commonly used in dashboards and monitoring applications to display key performance indicators, thresholds, and real-time metrics with clear visual cues such as ranges, tick marks, color-coded segments, and animated needles or pointers. Built to integrate with WPF’s data binding, templating, and styling capabilities, gauge controls allow developers to connect live data sources, customize appearance through themes and templates, and define ranges or alerts that highlight critical values. This makes them particularly useful in industrial systems, financial dashboards, health monitoring tools, and other applications where quick visual interpretation of numeric data is essential.

Many .NET WPF UI Suites contain gauges including:

  • DevExpress WPF lets you build interactive gauge controls with rich styling, real-time data binding, and dashboard-ready visual indicators and analytics.
  • Actipro WPF Studio allows you to integrate customizable radial and linear gauges featuring advanced theming and smooth animation support capabilities.
  • Nevron Vision for .NET enables developers to design advanced gauge visualizations with rich indicators, scales, and dynamic updates for data-driven dashboards.
  • MindFusion.WPF Pack facilitates interactive gauge components that display key values clearly, supporting animation, theming, and integration with WPF data sources.
  • Infragistics Ultimate UI for WPF lets you create sophisticated gauge visualizations with configurable ranges, responsive rendering, and dashboard presentation capabilities.
