使用 IRONPDF

PDF 庫用于 .NET 轉換器

已更新 2023年12月3日

在 C# .NET 庫中製作 PDF 是簡單且高效的，前提是有合適的指南。使用 IronPDF，我們能夠根據我們的應用需求簡單地創建和編輯 PDF 功能。以下是一個關於如何在您的專案中高效使用該軟體並只需點擊一個按鈕即可創建 PDF 的教程範例。!

第一步

1. 安裝 C# PDF 庫 .NET

訪問該庫的兩種主要方法是：

下載並解壓 DLL 檔案
導航 NuGet 並透過Visual Studio安裝套件。

Install-Package IronPdf

如何操作教程

2. 使用 PDF .NET 庫

現在我們有了軟體，我們可以生成PDF文件, 調整設置，添加自訂文字和圖像，和操作PDF文件符合我們的專案需求。

在下面的代碼中，我們使用了 C# 表單示範如何使用 C# .NET 庫創建 PDF。在這裡，我們有一個 TextBox 可以用來輸入自己的文字，然後只需按一下按鈕即可生成 PDF。ChromePdfRenderer 類提供了從不同來源生成 PDF 文件的最簡單辦法，包括 HTML 字串, Web網址，或在另一個渲染器下的doc文件.
