如何在ASP.NET Core中使用C#上傳和下載PDF文件 | IronPDF

This video walks through uploading and downloading PDF files in ASP.NET using C# and IronPDF. It covers accepting an uploaded PDF, working with the file stream, processing the document on the server, and delivering a PDF back to the user as a download. These are the building blocks behind document-management features, and the video shows how to wire the upload and download endpoints together in a .NET application. The same pattern scales from a single form to a full document pipeline.
