如何使用c＃代码在treeviewitem中创建图像

Question

我想在treeviewitem中创建一个图像，但我不能。我不知道我的错误在哪里。

#create treeviewitem的图片＃

            TreeViewItem tvt = new TreeViewItem();
            StackPanel stackPanel = new StackPanel();
            Label lblHeaderText = new Label();
            Label kk = new Label();
            Image imgFrontIcon;

            imgFrontIcon = new Image();


            string ImagePath = @"C:\Users\x\Desktop\y\HospitalProject\images\Untitled.png";
            if (ImagePath != null && ImagePath != string.Empty)
            {
                Uri uri = new Uri(ImagePath);
                BitmapImage bitMapSource = new BitmapImage();



                imgFrontIcon.Source = new BitmapImage(new Uri(ImagePath, UriKind.Relative));
            }

            lblHeaderText.Content = "ss";
            kk.Content = "lll";
            stackPanel.Children.Add(imgFrontIcon);
            stackPanel.Children.Add(lblHeaderText);
            stackPanel.Children.Add(kk);

            tvt.Name = "sef";
            tvt.Header = stackPanel;
            mytree.Items.Add(tvt);
