Webbrowser.DocumentStream or Webbrowser.DocumentText not working?
I can't figure out why this simple lines of code simply doesn't work:
// Bulding tree
var 开发者_开发问答declaration = new XDeclaration("1.0", "UTF-8", "yes");
var root = new XElement("root");
// Adding elements to document
var doc = new XDocument(declaration, root);
// Salve the stream
var stream = new MemoryStream();
doc.Save(stream);
// Update WebBrowser control
webBrowser1.DocumentStream = stream;
You're saving to the stream, leaving the "cursor" positioned at the end... and then giving it to the browser, which I suspect is reading from the current location. Try adding:
stream.Position = 0;
just before the last line.
EDIT: Okay, you say it's not working... here's a short but complete program which works for me. Try this and see if it works for you - and if it does, see if you can work out the difference between your code and this:
using System;
using System.Drawing;
using System.IO;
using System.Text;
using System.Windows.Forms;
class Test
{
[STAThread]
static void Main()
{
Form form = new Form();
WebBrowser browser = new WebBrowser();
browser.Dock = DockStyle.Fill;
form.Controls.Add(browser);
form.Load += delegate { SetDocumentStream(browser); };
Application.Run(form);
}
static void SetDocumentStream(WebBrowser browser)
{
string text = "<html><head><title>Stuff</title></head>" +
"<body><h1>Hello</h1></body></html>";
byte[] bytes = Encoding.UTF8.GetBytes(text);
MemoryStream ms = new MemoryStream();
ms.Write(bytes, 0, bytes.Length);
ms.Position = 0;
browser.DocumentStream = ms;
}
}
This is old, but....i was battling this for a while today and it didn't work until i isolated this line of code affecting the web browser control and commented it out:
AllowNavigation = false;
...so evidently this needs to be true. you can have everything else right and this will prevent it from working.
加载中,请稍侯......
