如何使用 Iron PDF 的 WaitFor 延遲 C# PDF 渲染

In this comprehensive tutorial, we delve into using IronPDF's WaitFor Class to delay PDF rendering in C#. Begin by installing the IronPDF package and setting up your project with the necessary imports and a valid license key. Learn about initializing a render object with Chrome PDF render and configuring immediate page load rendering using default settings. The tutorial further explores setting custom rendering delays, such as a 3,000-millisecond delay after page load, and how to save the generated PDF with the SaveAs method.

We discuss scenarios involving font readiness, utilizing the WaitFor.AllFontsLoaded method to ensure all fonts are loaded before rendering. Additionally, the tutorial demonstrates executing JavaScript within HTML strings to notify IronPDF to proceed with rendering after a delay. You'll learn to wait for specific HTML elements to load using methods like WaitFor.HtmlElementById and WaitFor.HtmlElementByName, crucial for scenarios requiring complete content loading before PDF generation.

Network conditions are also addressed, explaining the NetworkIdle conditions, which dictate rendering based on network activity levels. The tutorial concludes with executing the application to observe the rendering behaviors, showcasing how delay mechanisms and JavaScript interactions impact the final PDF document. By following these steps, you'll effectively leverage IronPDF's WaitFor Class to manage delays and execute JavaScript for precise PDF generation in your .NET applications.
