Question

我无法在项目中安装任何软件包。我需要安装ITextSharp软件包。

Answer 1

我做了很多研究，发现了一些对您有用的链接：

iTextSharp: Any support for dotnet core (netstandard1.6)?

所以iTextSharp不支持.NET Standard 的问题。如果仍要在项目中使用iTextSharp，则需要使用Xamarin Port。您可以下载iTextSharp的源代码，然后将其复制粘贴到Visual Studio中的新Xamarin类库项目中。

我发现以前有人这样做过，例如：Xam.iTextSharpLGPL。但是问题在于，这是基于iText的古老版本（2009年7月7日发行），它将永远不会获得更新或错误修复。

iText软件已经发布了iText 7的Xamarin端口，该端口将继续获得更新。 我认为您应该改用iText7。经过我的测试，我可以毫无问题地安装iText7。

希望这会对您有所帮助。

谢谢
