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。
