在webBrowser中添加HTML文件

Question

I'm a newbie with this. Here is my problem:

I want to call a HTML file located in my PC clicking a button like this (I'm using c#).

private void Button1_click(object sender, RoutedEventArgs e) 
{
 navegador.Navigate("C:/Users/aMan/Desktop/HelloWorld.html");
}

In which navegador is the name of the webBrowser control .

I was reading some notes that you answered before, even following the steps I can't get my webBrowser loads that file. So pretty please, with sugar on top, help me out.

Answer 1

I believe, correct me if I am wrong but you need the directory to be double slashed in order for it to work.

Uri HTMLPath = new Uri("C://Users//aMan//Desktop//HelloWorld.html");
navegador.Navigate(HTMLPath);

How about that?

Answer 2

Just add an @ before the string like so.

navegador.Navigate(@"C:/Users/aMan/Desktop/HelloWorld.html");

Your basic command is correct. It is just the either the @ or // slashes are required in strings so that .NET does not treat single slashes (/) as escape characters.

Also, (and this is just a bonus), the WebBrowser control does not function well with modern browsers and is not the most optimal way to retrieve Web content for a page.

Vb.net:

        Dim theFileHtml As String = System.IO.File.ReadAllText("c:\test1.txt")
        WebBrowser1.Navigate("")
        Do Until WebBrowser1.ReadyState = WebBrowserReadyState.Complete
            Application.DoEvents()
            System.Threading.Thread.Sleep(1)
        Loop
        WebBrowser1.Document.Body.InnerHtml = theFileHtml 'Also You Can Use WebBrowser1.DocumentText

C#:

string theFileHtml = System.IO.File.ReadAllText("c:\\test1.txt");
    WebBrowser1.Navigate("");
    while (WebBrowser1.ReadyState != WebBrowserReadyState.Complete) {
        Application.DoEvents();
        System.Threading.Thread.Sleep(1);
    }
        //Also You Can Use WebBrowser1.DocumentText
    WebBrowser1.Document.Body.InnerHtml = theFileHtml;
