  9. 在 ASP.NET Core MVC 中為 140 多種文件格式創建文檔查看器

    在線文檔查看器在數字文檔的使用越來越多之後變得流行起來，尤其是在內容管理系統中。這種流行背後的原因是您無需購買或安裝專用軟件程序即可查看各種文檔格式。考慮到文檔查看器的重要性，我想寫一篇關於如何在 ASP.NET MVC 中創建通用文檔查看器的文章。 我們將創建一個面向 [.NET Core](https://en.wikipedia. org/wiki/.NETCore) 框架。對於後端的文檔呈現，我們將使用 GroupDocs.Viewer for .NET API - 一個強大的文檔查看器 API，支持 140 多種文檔類型，包括 Pdf 、Word、Excel、PowerPoint, Visio、CAD、Outlook 和許多其他流行格式。 為什麼選擇 .NET 核心？ .NET Core 是 Microsoft 對 .NET 生態系統的重要補充。它使得開發跨平台應用程序成為可能，而無需開發人員進行任何額外的工作。這就是我選擇 .NET Core 作為目標框架的原因。 在 ASP.NET Core 中創建文檔查看器的步驟 打開 Visual Studio 並開始一個新項目。 從項目類型中選擇 .NET Core，從模板中選擇 ASP.NET Core Web Application。 選擇 Web Application (Model-View-Controller) 並單擊 Ok 按鈕。 從 NuGet 安裝 GroupDocs.Viewer。 打開 Views/Home/Index.cshtml 文件並將其內容替換為以下內容： @{ ViewData["Title"] = "Home Page"; }
