序列化自定义层次结构集合时出现问题
|
我必须填充一个已为其进行自定义集合的树视图
这是自定义集合的类
public class EntityBase : ObservableCollection<object>
{
private string name;
public string Name
{
get { return name; }
set
{
name = value;
InvokePropertyChange(this, new PropertyChangedEventArgs(\"Name\"));
}
}
public event PropertyChangedEventHandler PropertyChanged;
public void InvokePropertyChange(object sender, PropertyChangedEventArgs e)
{
if (PropertyChanged != null)
{
PropertyChanged(sender, e);
}
}
}
public class ParentX : EntityBase // Should be the root of my XML
{
}
public class Parent : EntityBase
{
private ChildC _childC;
public ChildC ChildC
{
get { return _childC; }
set { _childC = value; }
}
}
public class ChildA : EntityBase
{
}
public class ChildB : EntityBase
{
}
public class ChildC : EntityBase
{
private ObservableCollection<ChildB> children = new ObservableCollection<ChildB>();
public ObservableCollection<ChildB> Children
{
get { return children; }
set { children = value; }
}
}
这是我按层次结构顺序填充数据的方式,以便可以填充异构树...
public class DataBase
{
public ObservableCollection<object> GetData()
{
ChildB childB1 = new ChildB { Name = \"Parent 1 - ChildB 1\" };
ChildB childB2 = new ChildB { Name = \"Parent 1 - ChildB 2\" };
ChildA childA1 = new ChildA { childB1, childB2 }; // ChildA will have ChildB objects as its child
childA1.Name = \"Parent 1 - ChildA 1\";
ChildC childC = new ChildC{Name=\"CHildC\"};
for (int i = 0; i < 5; i++)
{
childC.Children.Add(new ChildB{Name=\"Pappu\" + i}); // childC children Property will have childB Object
}
Parent parent1 = new Parent {childC, childA1}; // Parent class will have ChildC and ChildA as its child
parent1.Name = \"Parent1\";
//Family 2
ParentX parentX=new ParentX{Name=\"Parent\"};
parentX.Add(parent1); //ParentX will have Parent as its child
return new ObservableCollection<object> { parentX };
}
}
这是我正在使用的序列化代码.....
using (FileStream fileStream=new FileStream(@\"D:\\text.xml\",FileMode.Create))
{
XmlSerializer xmlSerializer = new XmlSerializer(typeof(ParentX), new Type[] { typeof(Parent), typeof(ChildA), typeof(ChildC), typeof(ChildB)});
if (data != null) xmlSerializer.Serialize(fileStream, data);
}
我被困在这个.....它不序列化给出了错误....
{\"There was an error generating the XML document.\"}
\"The type HierarchialTreeView.Model.ChildC may not be used in this context.\"
请帮我解决这个问题
填充所需类型的异构树视图很困难,现在发生了这种情况
谢谢Ne的方式...社区非常有帮助:)
编辑:
内部异常:
{\“在此上下文中,不能使用类型HierarchialTreeView.Model.ChildC。\”}
内在异常= null
此后没有更多例外了。。。。
