• Font序列化和反序列化


    Font中的Properties都是readonly,并且Font不能被继承,所以序列化和反序列化Font会相对麻烦一点。

    需要写一个FontSerializer类来实现Font序列化和反序列化。先写测试代码:

            [TestMethod()]
            public void FontSerializationTest()
            {
                const string _anyFileName = @"D:/FontSerializerTest.xml";
    
                XmlTextWriter writer = new XmlTextWriter(_anyFileName, null);
                writer.Formatting = Formatting.Indented;
                string name = "Font";
                Font font = new Font("Arial", 9, FontStyle.Bold | FontStyle.Italic | FontStyle.Strikeout | FontStyle.Underline);;
                FontSerializer.WriteXml(writer, name, font);
                writer.Close();
                font.Dispose();
    
                XmlTextReader reader = new XmlTextReader(_anyFileName);
                font = FontSerializer.ReadXml(reader, name);
                reader.Close();
                Assert.AreEqual(font.Name, _anyFont.Name);
                Assert.AreEqual(font.Size, _anyFont.Size);
                Assert.AreEqual(font.Style, _anyFont.Style);
                font.Dispose();
            }
    

    再写实现代码。

    using System.Drawing;
    using System.Globalization;
    using System.Xml;
    
    namespace CommonLib
    {
        public static class FontSerializer
        {
            #region Methods
    
            public static Font ReadXml(XmlReader reader, string name)
            {
                reader.ReadToFollowing(name);
                reader.ReadStartElement();
                string familyName = reader.ReadElementString("Name");
                float size = float.Parse(reader.ReadElementString("Size"), CultureInfo.InvariantCulture);
                bool bold = bool.Parse(reader.ReadElementString("Bold"));
                bool italic = bool.Parse(reader.ReadElementString("Italic"));
                bool strikeout = bool.Parse(reader.ReadElementString("Strikeout"));
                bool underline = bool.Parse(reader.ReadElementString("Underline"));
                reader.ReadEndElement();
    
                FontStyle fontStyle = FontStyle.Regular;
                if (bold) fontStyle |= FontStyle.Bold;
                if (italic) fontStyle |= FontStyle.Italic;
                if (strikeout) fontStyle |= FontStyle.Strikeout;
                if (underline) fontStyle |= FontStyle.Underline;
                Font font = new Font(familyName, size, fontStyle); 
                return font;
            }
    
            public static void WriteXml(XmlWriter writer, string name, Font font)
            {
                writer.WriteStartElement(name);
                writer.WriteElementString("Name", font.Name);
                writer.WriteElementString("Size", font.Size.ToString(CultureInfo.InvariantCulture));
                writer.WriteElementString("Bold", font.Bold.ToString());
                writer.WriteElementString("Italic", font.Italic.ToString());
                writer.WriteElementString("Strikeout", font.Strikeout.ToString());
                writer.WriteElementString("Underline ", font.Underline.ToString());
                writer.WriteEndElement();
            }
    
            #endregion
        }
    }
    

    见人用过Stream和BinaryFormatter序列化和反序列化Font,但不能在XML文件中任意节点序列化Font。以上实现可以解决这个问题。
