问题描述
我程序里要用到几种自定义的对象，一共是9个对象。每一个对象有不同的属性（我把它定义成结构体了）。其中对象1的属性是结构体LEDWindowsAttribute对象2、对象3的属性是结构体TextWindowsAttribute对象4、对象5、对象6、对象7、对象8、对象9的属性是结构体TimeWindowsAttribute对象1是父节点（只有一个）对象2------对象8是子节点。我通过程序上的按钮操作动态的增加或删除子节点（用TreeView显示父节点和子节点，子节点里有重复对象比如有3个对象2，且子节点数量可能很多）。我怎么才能将节点关系及对象属性序列化并存储成XML格式的文件，怎么反序列化XML文件解析还原得到TreeView上的树状结构和各个节点的属性。希望大神能给出代码或思路。TreeView上的表现形式如下所示对象1的NodeText值|----对象2的NodeText值|----对象3的NodeText值|----对象4的NodeText值|----对象5的NodeText值|----对象2的NodeText值|----对象6的NodeText值|----对象3的NodeText值。。。。。。以下是我定义的几个对象属性//////单行文字和多行文字对象窗口的属性///publicstructTextWindowsAttribute{[XmlAttribute("NodeName")]publicstringNodeName;//节点名字[XmlElement("NodeText")]publicstringNodeText;//节点文本[XmlElement("NodeIndex")]publicintNodeIndex;//节点序号[XmlElement("X")]publicintX;//X坐标[XmlElement("Y")]publicintY;//Y坐标[XmlElement("Width")]publicintWidth;//宽度[XmlElement("Height")]publicintHeight;//高度[XmlElement("Text")]publicstringText;//文字[XmlElement("FontName")]publicstringFontName;//字体[XmlElement("FontSize")]publicfloatFontSize;//字号[XmlElement("FontBold")]publicboolFontBold;//是否粗体[XmlElement("FontItalic")]publicboolFontItalic;//是否斜体[XmlElement("FontUnderline")]publicboolFontUnderline;//是否有下划线[XmlElement("FontColor")]publicintFontColor;//文字颜色}//////时间对象窗口的属性///publicstructTimeWindowsAttribute{[XmlAttribute("NodeName")]publicstringNodeName;//节点名字[XmlElement("NodeText")]publicstringNodeText;//节点文本[XmlElement("NodeIndex")]publicintNodeIndex;//节点序号[XmlElement("X")]publicintX;//X坐标[XmlElement("Y")]publicintY;//Y坐标[XmlElement("Width")]publicintWidth;//宽度[XmlElement("Height")]publicintHeight;//高度[XmlElement("FontName")]publicstringFontName;//字体[XmlElement("FontSize")]publicfloatFontSize;//字号[XmlElement("FontBold")]publicboolFontBold;//是否粗体[XmlElement("FontItalic")]publicboolFontItalic;//是否斜体[XmlElement("FontUnderline")]publicboolFontUnderline;//是否有下划线[XmlElement("FontColor")]publicintFontColor;//文字颜色}//////LED显示屏对象窗口的属性///publicstructLEDWindowsAttribute{[XmlAttribute("NodeName")]publicstringNodeName;//节点名字[XmlElement("NodeText")]publicstringNodeText;//节点文本[XmlElement("NodeIndex")]publicintNodeIndex;//节点序号[XmlElement("X")]publicintX;//X坐标[XmlElement("Y")]publicintY;//Y坐标[XmlElement("Width")]publicintWidth;//宽度[XmlElement("Height")]publicintHeight;//高度}

解决方案四：
调用方法，box是一个textbox至于如何加载到treeview就靠你自己了varroot=NodeFactory.Create<LedNode>("LED","LED",0);for(inti=0;i<8;i++){vars=string.Format("Text{0}",i+1);varchild=NodeFactory.Create<TextNode>(s,s,i,s,root);if(i%3==0){child.Font.Color=System.Drawing.Color.Red;child.Font.Style=System.Drawing.FontStyle.Bold|System.Drawing.FontStyle.Underline;}root.Children.Add(NodeFactory.Create<TextNode>(s,s,i,s,root));}for(inti=0;i<3;i++){vars=string.Format("Time{0}",i+1);varchild=NodeFactory.Create<TimeNode>(s,s,i,root);if(i==2){child.Font.Color=System.Drawing.Color.Blue;child.Font.Style=System.Drawing.FontStyle.Bold|System.Drawing.FontStyle.Italic;}root.Children.Add(child);}varxml=root.Serialize();box.AppendText(xml);varnode=NodeFactory.Create<LedNode>(xml);foreach(varchildinnode.Children){box.AppendText(string.Format("{0}:{1}rn",child.GetType(),child.Name));}
