C#实现在PDF文档中应用多种不同字体_C#

引入dll

本次程序中引入的是Spire.Pdf.dll，引入方法如下：

【方法1】通过NuGet安装。

可以在Visual Studio中打开“解决方案资源管理器”，鼠标右键点击“引用”，“管理NuGet包”，然后搜索“Free Spire.PDF”，点击“安装”。

也可以将以下内容复制到PM控制台安装：

Install-Package FreeSpire.PDF -Version 7.8.9

【方法2】手动安装。

可通过手动下载Free Spire.PDF for .NET包，然后解压，找到BIN文件夹下的Spire.Pdf.dll。在Visual Studio中打开“解决方案资源管理器”，鼠标右键点击“引用”，“添加引用”，将本地路径BIN文件夹下的dll文件添加引用至程序。
