.Net WebBrowser.DocumentText没有改变！ [英] .Net WebBrowser.DocumentText Isn't Changing!
问题描述
在我的vb.net程序中，我使用web浏览器向用户显示HTML预览。我以前打过一台服务器来抓取HTML，然后返回一个异步线程，并引发一个事件，用我返回的HTML字符串填充WebBrowser.DocumentText。
In my vb.net program, I am using a webbrowser to show the user an HTML preview. I was previously hitting a server to grab the HTML, then returning on an asynchronous thread and raising an event to populate the WebBrowser.DocumentText with the HTML string I was returning.
现在，我设置它来获取客户端上的所有信息，而无需打开服务器，我正在尝试提交相同的事件。我注意到代码已经过去了，它的HTML字符串是正确的，但是当我尝试做的时候
Now I set it up to grab all of the information on the client, without ever having to hit the server, and I'm trying to raise the same event. I watch the code go through, and it has the HTML string correct and everything, but when I try to do
browser.DocumentText = _emailHTML
DocumentText的内容保留为< HTML>< / HTML>>
the contents of DocumentText remain as "<HTML></HTML>"
我只是想知道为什么没有设置DocumentText。任何人有任何建议吗？
I was just wondering why the DocumentText was not being set. Anyone have any suggestions?
推荐答案
请尝试以下操作：
Try the following:
browser.Navigate("about:blank");
HtmlDocument doc = browser.Document;
doc.Write(String.Empty);
browser.DocumentText = _emailHTML;
我发现 WebBrowser 控件通常需要初始化为 about：blank ，无论如何。在导航到不同类型的内容（如text / xml到text / html）之间需要完成相同的工作，因为渲染器是不同的（mshtml for text / html，其他文本/ xml文件）。
I've found that the WebBrowser control usually needs to be initialized to about:blank anyway. The same needs to be done between navigates to different types of content (like text/xml to text/html) because the renderer is different (mshtml for text/html, something else for text/xml).
