c＃webbrowser编码以本地导航到html

Question

I'm trying to put a local html location address to the web browser in my C# application but always failed. I'm using debug mode now so the html files had already copied into my Debug folder because i put copy always in the copy to output option. Below is my code:

        string appPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);
        string filePath = Path.Combine(appPath, "index.html");
        webBrowser1.Navigate(new System.Uri(@"file://"+ filePath));

There always this error coming out using that way:

An unhandled exception of type 'System.UriFormatException' occurred in System.dll

Any idea what went wrong?

Answer 1

Its a bit unclear but try this out. Hope this may help.

webBrowser1.Navigate(new Uri(@"your File Name"))

Or

webBrowser1.Navigate(new Uri(AppDomain.CurrentDomain.BaseDirectory == "\\File Name")

Edit: May be this causing error,

webBrowser1.Navigate(new System.Uri("@" filePath + "file://"));

Answer 2

You just need to change your code slightly - here is the correct syntax:

string appPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);
string filePath = Path.Combine(appPath, "index.html");
webBrowser1.Navigate(new System.Uri(filePath));

The issue is that CodeBase returns the path in URI format already so you do not need to add the additional the "file://" to the path.
