在 WPF HTML 数据绑定时间异常未知名称。（HRESULT 异常：0x80020006（DISP_E_UNKNOWNNAME））

Question

我正在将 WPF 与 .Net 结合使用。在应用程序中，我在网页上携带 HTML 内容，然后生成了数据绑定时间异常。而在调试时没有产生任何异常。这是我的代码 -

public ReopemForm(string policyno)
    {
        InitializeComponent();
        InitailSetup();                      
        pghReopenForm.lblPageHeader.Content = "Agency Add Edit";
        pghReopenForm.lblPageHeader.Visibility = Visibility.Visible;
        pghReopenForm.imgPanel.Visibility = Visibility.Hidden;
        PolicyNo = policyno;
       
    }

private void InitailSetup()
    {
        this.Height = System.Windows.SystemParameters.PrimaryScreenHeight - 130;
        mainGrid.MaxHeight = Height - 50;
        pghReopenForm.Close_Click += btnClose_Click;
        pghReopenForm.Minimize_Clik += btnMinimize_Click;
        pghReopenForm.PageTitle = "Policy Add";
        string curDir = Directory.GetCurrentDirectory();
        string countryPath = AILClasses.AILGlobal.CurrentUser.CountryId;
        string ProvincePath = AILClasses.AILGlobal.CurrentUser.ProvinceId;
        string htmlPath = String.Format("file:///{0}/Forms/{1}/{2}/ReopenForm.html", curDir, countryPath, ProvincePath);
        var str = new Uri(htmlPath);
        myWebBrowser.Navigate(str);
        myWebBrowser.Width = frmCustomerAddEdit.Width - 10;
        myWebBrowser.LoadCompleted += MyWebBrowser_LoadCompleted;
        
       
    }

private void MyWebBrowser_LoadCompleted(object sender, System.Windows.Navigation.NavigationEventArgs e)
    {
        try
        {
            //string functionUsername = string.Format(@"document.getElementById('txtappNumber').value = "+ PolicyNo + ";");
            // var xyz = myWebBrowser.InvokeScript("eval", new string[] { functionUsername });
            string[] txtappnum = { "txtappNumber", PolicyNo };               
            this.myWebBrowser.InvokeScript("SetKeyValue", txtappnum);
            string[] lblAppnum = { "lblappNumber", PolicyNo };                
            this.myWebBrowser.InvokeScript("SetKeyValuehtml", lblAppnum);
            string[] dateargs = { "txtdate", DateTime.Now.ToShortDateString() };
            this.myWebBrowser.InvokeScript("SetKeyValue", dateargs);                
            string[] datelbl = { "lbldate", DateTime.Now.ToShortDateString() };
            this.myWebBrowser.InvokeScript("SetKeyValuehtml", datelbl);                
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message.ToString());
        }
    }

请帮我解决这个问题。谢谢
