public:
 void Navigate(System::String ^ source, System::String ^ targetFrameName, cli::array <System::Byte> ^ postData, System::String ^ additionalHeaders);

public void Navigate (string source, string targetFrameName, byte[] postData, string additionalHeaders);

member this.Navigate : string * string * byte[] * string -> unit

Public Sub Navigate (source As String, targetFrameName As String, postData As Byte(), additionalHeaders As String)

Parameters

Examples

The following example shows how to navigate to a document and open it in a new browser window by specifying the "about:blank" target.

<StackPanel>  
    <StackPanel Orientation="Horizontal">  
        <TextBox x:Name="addressTextBox" Width="200" />  
        <Button Click="goNavigateButton_Click">Go</Button>  
    </StackPanel>  
    <WebBrowser x:Name="myWebBrowser" />  
</StackPanel>

private void goNavigateButton_Click(object sender, RoutedEventArgs e)  
{  
    // Get URI to navigate to  
    Uri uri = new Uri(this.addressTextBox.Text, UriKind.RelativeOrAbsolute);  

    // Only absolute URIs can be navigated to  
    if (!uri.IsAbsoluteUri)  
    {  
        MessageBox.Show("The Address URI must be absolute. For example, 'http://www.microsoft.com'");  
        return;  
    }  

    // Navigate to the desired URL by calling the .Navigate method  
    this.myWebBrowser.Navigate(uri, "_blank", null, null);  
}

member this.Navigate : Uri -> unit

Public Sub Navigate (source As Uri)

Parameters

source: Uri

The Uri to navigate to.

Exceptions

ObjectDisposedException

The WebBrowser instance is no longer valid.

InvalidOperationException

A reference to the underlying native WebBrowser could not be retrieved.

SecurityException

Navigation from an application that is running in partial trust to a Uri that is not located at the site of origin.

Examples

The following example shows how to use WebBrowser to navigate to a document by using the Navigate(Uri) method.

<StackPanel>  
    <StackPanel Orientation="Horizontal">  
        <TextBox x:Name="addressTextBox" Width="200" />  
        <Button Click="goNavigateButton_Click">Go</Button>  
    </StackPanel>  
    <WebBrowser x:Name="myWebBrowser" />  
</StackPanel>

private void goNavigateButton_Click(object sender, RoutedEventArgs e)  
{  
    // Get URI to navigate to  
    Uri uri = new Uri(this.addressTextBox.Text, UriKind.RelativeOrAbsolute);  

    // Only absolute URIs can be navigated to  
    if (!uri.IsAbsoluteUri)  
    {  
        MessageBox.Show("The Address URI must be absolute. For example, 'http://www.microsoft.com'");  
        return;  
    }  

    // Navigate to the desired URL by calling the .Navigate method  
    this.myWebBrowser.Navigate(uri);  
}

Remarks

Calling Navigate(Uri) has the same effect as setting the Source property. Source is used from markup by developers who want to declaratively specify the initial document that WebBrowser navigates to when WebBrowser is initialized.

Use the Navigate(String) method to navigate to a URL that may include escape characters. Use the Navigate(Uri) method to navigate to a Uri that does not include escape characters.
