gre*_*emo 2 c# browser stream linq-to-xml webbrowser-control
我无法弄清楚为什么这些简单的代码行根本不起作用:
// Bulding tree
var 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;
您将保存到流中,将"光标"保留在末尾...然后将其提供给浏览器,我怀疑它是从当前位置读取的.尝试添加:
stream.Position = 0;
就在最后一行之前.
编辑:好的,你说它不起作用......这是一个简短但完整的程序,对我有用.试试这个,看看它是否适合你 - 如果确实如此,看看你是否能解决你的代码和这个之间的区别:
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;
}
}
