Silverlight智能表单(3)之XML存储
时间：2011-01-24 来源：无名菜鸟
我最初的想法是存储到xml文件中，OK，说一下我的大体构架，该构架挺失败的（至少我是这样认为），但是我也没有其他更好的想法了，如果哪天想到了，我就努力完成这个智能表单的程序。
1.工具栏中所有的控件全部存储到XML文件中，其中包括各个控件的默认值。（ps：包括该控件的全名（如：System.Windows.Controls.Button）以及AssemblyName（如：System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e），如果有了这两个字段的话就可以反射出该控件了。）
2.生成好的表单存储成XML。包括表单的一些属性，以及各个控件及属性。
问题1：
如果存储成Xml，我想到的最好的办法是序列化。
OK开代码：（所有的控件前面加了一个X）
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XTextBox))]
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XTextBlock))]
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XButton))]
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XPasswordBox))]
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XCheckBox))]
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XRadioButton))]
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XComboBox))]
[System.Xml.Serialization.XmlIncludeAttribute(typeof(XDatePicker))]
public class XFrameworkElement : Bases.ViewModelBase
{
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public double Height
{
get;set;
}
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public double Width
{
get;set;
}
//........意思下，省略。。。
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public string CtrlName { get; set; }
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public string TypeName{ get; set; }
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public string AssemblyName{ get; set; }
}
如果你想忽略某个属性不进行序列化就使用[System.Xml.Serialization.XmlIgnore]，XmlElementAttribute这个类中有很多属性如ElementName，如果不知道看msdn。因为不同的控件属性也不一样，所以就需要定义不同的类，继承方式和类库中的一致（但不一定相同），类头上的那个定制属性中的类都是XFrameworkElement 的子类。
对于ViewModelBase类我贴下代码：
//一看都知道是干什么的，不知道的百度或者谷歌下，你不知道肯定也有人不知道，一定会有人问的，也一定会有人答的。
public class ViewModelBase : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
public void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
问题2：
因为我设想的是要反射出来所有的控件，但是有点问题，因为像TypeName不是控件的属性，需要区分开来。我的办法依旧是反射，定义一个定制属性：
[AttributeUsage(AttributeTargets.Property, Inherited = false, AllowMultiple = false)]
public class FromCtrlAttribute : Attribute{}
就这么简单，什么都没有，它的意思指明该属性和控件中的属性一致。
于是乎：
[FromCtrlAttribute]
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public double Height{get;set;}
[FromCtrlAttribute]
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public double Width{get;set;}
然后我的创建控件的方法就出来了：
protected virtual FrameworkElement CreateControl()
{
return CreateControl(this);
}
protected virtual FrameworkElement CreateControl(XFrameworkElement xControl)
{
Assembly assembly = Assembly.Load(AssemblyName);
Type type = assembly.GetType(TypeName);
if (type != null)
{
//m_Control定义：internal FrameworkElement m_Control;
m_Control = Activator.CreateInstance(type) as FrameworkElement;
PropertyInfo[] ctrlProperties = type.GetProperties(BindingFlags.Public | BindingFlags.GetProperty | BindingFlags.SetProperty);
PropertyInfo[] thisProperties = xControl.GetType().GetProperties();
foreach (var item in thisProperties)
{
if (item.GetCustomAttributes(typeof(FromCtrlAttribute), false).Length > 0)
{
//item.Name
foreach (var property in ctrlProperties)
{
if (property.Name == item.Name)
{
property.SetValue(m_Control, item.GetValue(xControl, null), null);
}
}
}
}
}
return m_Control;
}
于是该类中的控件就被反射出来了。ps：AssemblyName和TypeName的值从哪里来？看第一个标号1，所有的控件包括默认值，我已经定义在xml文件中。
问题3：
先上一个图看一下：
不用多介绍了，红色的为我们的画板，右侧是一个DataForm控件。对于Background，FontWeight等属性，DataForm无法识别，不能够生成下拉框。
继续反射,先贴代码，然后再动嘴皮子。
using System;
using System.Reflection;
using System.Windows;
using System.Windows.Input;
using System.Windows.Media;
namespace DragDrop.Bases
{
public class EnumCommon
{
public static object GetActValue(Type type, string value)
{
object actValue = null;
object[] attributes = type.GetCustomAttributes(false);
foreach (var attr in attributes)
{
if (attr is SourceAttribute)
{
Type sourcetype = (attr as SourceAttribute).SourceType;
PropertyInfo[] properties = sourcetype.GetProperties();
foreach (var property in properties)
{
if (property.Name.Equals(value))
{
actValue = property.GetValue(null, null);
return actValue;
}
}
}
}
return actValue;
}
}
[SourceAttribute(typeof(Colors))]
public enum ColorEnum
{
Black,
Blue,
Brown,
Cyan,
DarkGray,
Gray,
Green,
LightGray,
Magenta,
Orange,
Purple,
Red,
Transparent,
White,
Yellow,
}
[SourceAttribute(typeof(Cursors))]
public enum CursorEnum
{
Arrow,
Eraser,
Hand,
IBeam,
None,
SizeNESW,
SizeNS,
SizeNWSE,
SizeWE,
Stylus,
Wait,
}
[SourceAttribute(typeof(FontWeights))]
public enum FontWeightEnum
{
Black,
Bold,
ExtraBlack,
ExtraBold,
ExtraLight,
Light,
Medium,
Normal,
SemiBold,
Thin,
}
[AttributeUsage(AttributeTargets.Enum, Inherited = false, AllowMultiple = false)]
public class SourceAttribute : Attribute
{
public SourceAttribute(Type sourceType)
{
SourceType = sourceType;
}
public Type SourceType { get; private set; }
}
}
1.以CursorEnum为例，控件中的定义为：
[FromCtrlAttribute]
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public Bases.CursorEnum Cursor{get;set;}
2.SourceAttribute该属性说明CursorEnum枚举中的成员来自于Cursors类。（注意观察Cursors，Colors等类public static Cursor Arrow{ get; }几乎都是这样定义的都有public和static）
3.GetActValue()该方法的使用如：m_Control.Cursor = (Cursor)Bases.EnumCommon.GetActValue(typeof(Bases.CursorEnum), value.ToString());
返回值为object类型，然后你强制转化为你所需要的类型即可。property.GetValue(null, null); 这个用法我也不太清楚，随手一用居然返回值就是我所需要的。
如此一来，一些乱七八糟的东西也能够在DataForm中编辑了，还有一点需要说明的是Cursor现在是一个枚举了，当然也可以序列化了，可谓一箭双雕。
4.看下这个属性
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public string CtrlName;// { get; set; }
我把get和set去掉了，变成了一个字段。主要原因是字段不会在DataForm中进行编辑的（最下面有详细代码）
（就是给你一个表的名称，你要实现添加删除更新，以及各种限制），感觉有点类似，还有原因是现在表单都没有设计好，于是数据库的建立等等没有考虑。
过几天分享那个控件的代码。
