保存TextBox中的文字为Path功能

今天再设计一个我自己程序的Icon时使用了Path+textbox做了图形，我不想导出为PNG，因为颜色比较单一，我又想通过代码控制颜色，所以我想完整的保存为Path。所以做了这个软件，支持设置不同的字体和字号，然后点击获取Path，就导出了path。然后粘贴到想用的地方即可。

using System;
using System.Globalization;
using System.Windows;
using System.Windows.Media;

namespace TextTransformationPath
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent(); 
        }

        [Obsolete]
        public string CreateText(string text)
        {
            System.Windows.FontStyle fontStyle = FontStyles.Normal;
            FontWeight fontWeight = FontWeights.Medium; 
            var pixelsPerDip = VisualTreeHelper.GetDpi(this).PixelsPerDip; 
            FormattedText formattedText = new FormattedText(
                text,
                CultureInfo.GetCultureInfo("en-us"),
                FlowDirection.LeftToRight,
                new Typeface(
                    new FontFamily(cbo_fontFamily.SelectedItem.ToString()),
                    fontStyle,
                    fontWeight,
                    FontStretches.Normal),
                Convert.ToInt32(FontSizeTextBox.Text),
                System.Windows.Media.Brushes.Black,  
               pixelsPerDip
                ); 
            // Build the geometry object that represents the text.
            var _textGeometry = formattedText.BuildGeometry(new System.Windows.Point(0, 0));

            // Build the geometry object that represents the text highlight.
            var res = PathGeometry.CreateFromGeometry(_textGeometry).ToString();
            return res;
        }

        private void GetTextTransformPath_Click(object sender, RoutedEventArgs e)
        {
            ResultPathTextBox.Text= CreateText(SourceText.Text);
        }
    }
}
