如何打开XML文件,重新绘制控件

1、加载XML文件

XElement root = XElement.Load(openFile.FileName);

 

2、针对每个XElement，反序列化

IEnumerable<XElement> itemsXML =root.Elements("DesignerItems").Elements("DesignerItem"); foreach (XElement itemXML in itemsXML) { DesignerItem item = DeserializeDesignerItem(itemXML, id, 0, 0); this.Children.Add(item); SetConnectorDecoratorTemplate(item); } private static DesignerItem DeserializeDesignerItem(XElement itemXML, Guid id, double OffsetX, double OffsetY) { DesignerItem item = new DesignerItem(id); item.Width = Double.Parse(itemXML.Element("Width").Value, CultureInfo.InvariantCulture); item.Height = Double.Parse(itemXML.Element("Height").Value, CultureInfo.InvariantCulture); item.ParentID = new Guid(itemXML.Element("ParentID").Value); item.IsGroup = Boolean.Parse(itemXML.Element("IsGroup").Value); Canvas.SetLeft(item, Double.Parse(itemXML.Element("Left").Value, CultureInfo.InvariantCulture) + OffsetX); Canvas.SetTop(item, Double.Parse(itemXML.Element("Top").Value, CultureInfo.InvariantCulture) + OffsetY); Canvas.SetZIndex(item, Int32.Parse(itemXML.Element("zIndex").Value)); Object content = XamlReader.Load(XmlReader.Create(new StringReader(itemXML.Element("Content").Value))); item.Content = content; return item; }

 

3、在Canvas中添加这些控件

 this.Children.Add(connection);
