ذخیره آیتم های متریال دیزاین در فایل

من از متریل دیزاین استفاده میکنم , تنظیم کردم که کاربر رنگ مورد نظر رو برای تم انتخاب کنه و بعد اون رنگ رو ست میکنم

منتهامیخوام برای اینکه این تم نرم افزار ذخیره بشه به شکلی که موقع اجرای مجددا برنامه  تم رو از فایل سیو شده بخونه

مسئله اینه نمیدونم چجوری میتونم این نوع رو توی یک فایل بنویسم ؟

private void MyColorPicker1_PreviewMouseMove(object sender, MouseEventArgs e)
{
        string filepath = @"C:\Themses";

        if (e.LeftButton == MouseButtonState.Pressed)
        {
            ITheme theme = _paletteHelper.GetTheme();

            theme.SetPrimaryColor(Color.FromRgb(MyColorPicker1.Color.R, MyColorPicker1.Color.G, MyColorPicker1.Color.B)); //red

            var Test = theme.GetBaseTheme();

            // something here to write all setting inside of ITheme into the text file

		// اینجا اون تم رو محتویاتش رو توی یک فایل بنویسم 
            //

            _paletteHelper.SetTheme(theme);
        }
}
