尝试在我正在编写的 Outlook 加载项中获取 WebBrowser 的 .Url 属性时出现“访问冲突”运行时错误。需要一些帮助来解决这个问题。研究表明我可能需要设置“FullTrust”权限集,但没有成功。

using System.Windows.Forms;
using System.Security;
using System.Security.Permissions;

namespace MyAddin1
{

public partial class authForm : Form
{

    public string currentUrl;

    public authForm()
    {
        InitializeComponent();
    }


    private void formLoaded(object sender, EventArgs e)
    {
        WebBrowser browser = new WebBrowser();
        browser.Location = new System.Drawing.Point(0, 0);
        browser.Width = 870;
        browser.Height = 510;
        browser.Navigate("https://www.yammer.com/dialog/oauth?client_id=<redacted>&response_type=token");
        browser.Show();

        //runtime error occurs on following line
        currentUrl = browser.Url.ToString();


        browser.Url = new Uri("http://www.yahoo.com");

        browser.Navigated += new WebBrowserNavigatedEventHandler(checkForToken);


        this.Controls.Add(browser);
    }

    private void checkForToken(object sender, EventArgs e)
    {
        MessageBox.Show(currentUrl);
    }




}

}

browser.Url最初为空,更改您的代码如下。

if (browser.Url != null)
{
    currentUrl = browser.Url.ToString();
}
