问题
I have an WPF application which uses a <WebBrowser> object to display some content which is in turn wrapped in HTML -- I want to generate that HTML on the fly, but it will hold links to different kinds of static content which will be local files. In a normal web application, I would try to use relative URIs for this -- they will be looked up relative to the URI of the dynamic page.
The problem is if I use WebBrowser.NavigateToStream (or .NavigateToString). In this case what is the "root" URI used for resolving relative links? Can I control it? Is it fixed? Perhaps relative Uris are simply banned in such data streams.
回答1:
Try adding <base href="root_path"> into the <head> section of the generated page. It works with NavigateToString, at least:
this.webBrowser.NavigateToString(
@"<head><base href='file://C:\Users\User\Documents\'></head><body><img src='image.jpg'></body>");
