WebBrowser控件缓存问题 [英] WebBrowser control caching issue

问题描述

我使用的是Windows窗体里面WebBrowser控件来显示PDF。

I am using the WebBrowser control inside a Windows Form to display a PDF.

每当PDF再生，但是，WebBrowser控件只显示其本地缓存版本，而不是从服务器更新的版本。

Whenever the PDF is regenerated, however, the WebBrowser control only displays its local cached version and not the updated version from the server.

我使用如下所示的刷新（）方法来尝试并强制控制重新加载PDF，但它不工作：

I am using the Refresh() method shown below to try and force the control to reload the PDF, but it doesn't work:

_webBrowser.Navigate(pdfUrl);

_webBrowser.Refresh(WebBrowserRefreshOption.Completely)

我必须做别的强制刷新重新加载来自服务器的PDF？

Do I have to do anything else to force the refresh to reload the PDF from the server?
