public static DependencyProperty Register(string name, Type propertyType, Type ownerType);

参数1:注册的从属属性的名子,该值赋给Name属性

参数2:属属性的数据类型,该值赋给PropertyType属性

参数3:再将将从属性性注册到的类,该值赋给OwnerType属性

重载2

public static DependencyProperty Register(string name, Type propertyType, Type ownerType, PropertyMetadata defaultMetadata);

参数1:注册的从属属性的名子,该值赋给Name属性

参数2:属属性的数据类型,该值赋给PropertyType属性

参数3:再将将从属性性注册到的类,该值赋给OwnerType属性

参数4:从属性性的默认值,该值赋给DefaultMetadata属性

public Activity1: SequenceActivity

{

  //从属属性A

public static DependencyProperty BProperty = DependencyProperty.Register("B", typeof(string), typeof(Activity1));

public string B

{

get{ return ((string)(base.GetValue(Activity1.BProperty)));}

set{ base.SetValue(Activity1.BProperty, value); }

}

//从属属性B

public static DependencyProperty AProperty = DependencyProperty.Register("A", typeof(string), typeof(Activity1),new PropertyMetadata("love"));

public string A

{

get{return ((string)(base.GetValue(Activity1.AProperty)));}

set{base.SetValue(Activity1.AProperty, value);}

}

}

说明:

对应的属性名，与注册的从属属性名，可以不一样，但最好一样

静态的从属属性与注册的从属属性名的格式必须是: [名Property] 与 [名] 的格式，如:

BProperty = DependencyProperty.Register("B",

AProperty = DependencyProperty.Register("A"

类.从属属性.DefaultMetadata

得到从属性性的默认值

类.从属属性.Name

得到从属属性的名子

类.从属属性.OwnerType

得到该从属属性所属的类

类.从属属性.PropertyType

得到从属属性的数据类型

System.Console.WriteLine(Activity1.AProperty.DefaultMetadata.DefaultValue);

System.Console.WriteLine(Activity1.AProperty.IsAttached);

System.Console.WriteLine(Activity1.AProperty.IsEvent);

System.Console.WriteLine(Activity1.AProperty.Name);

System.Console.WriteLine(Activity1.AProperty.OwnerType);

System.Console.WriteLine(Activity1.AProperty.PropertyType);

System.Console.WriteLine(Activity1.AProperty.ValidatorType);

 public static DependencyProperty FromName(string propertyName, Type ownerType);

返回值:从属属性对象

参数1:从属属性的名称，即Name的字符串

参数2:要操作的包含从属属性的类

例

            DependencyProperty p = DependencyProperty.FromName("A", typeof(Activity1));

            System.Console.WriteLine(p.DefaultMetadata.DefaultValue);

            System.Console.WriteLine(p.IsAttached);

            System.Console.WriteLine(p.IsEvent);

            System.Console.WriteLine(p.Name);

            System.Console.WriteLine(p.OwnerType);

            System.Console.WriteLine(p.PropertyType);

            System.Console.WriteLine(p.ValidatorType);

 public static IList<DependencyProperty> FromType(Type ownerType);

返回值:从属属性集合

参数1:要操作的包含从属属性的类

            System.Collections.Generic.IList<DependencyProperty> pls;

            pls = DependencyProperty.FromType(typeof(Activity1));

            foreach (DependencyProperty temp in pls)

            {

                System.Console.WriteLine(temp.Name);

            }

    public class w : System.Workflow.ComponentModel.DependencyObject

    {

       private static DependencyProperty pProperty;

    }

            DependencyProperty p = DependencyProperty.Register("p", typeof(string), typeof(w));

            w obj = new w();

            obj.SetValue(p, "123");

            object v = obj.GetValue(p);

            System.Console.WriteLine(v);

public void SetValue(DependencyProperty dependencyProperty, object value);

实例.SetValue(类.从属属性,值)

public object GetValue(DependencyProperty dependencyProperty);

值 = 实例.SetValue(类.从属属性)

private Activity1 activity11;

activity11 = new Activity1();

activity11.SetValue(Activity1.AProperty, "值");

object v = activity11.GetValue(Activity1.AProperty);

Name:要绑定Activity对象实例的Name

Path:要绑定的Activity对象属性

从属属性所在Activity对象.SetBinding(Activity对象类.从属属性,ActivityBind对象)

从属属性所在Activity对象.RemoveProperty(Activity对象类.从属属性)

System.Workflow.ComponentModel.ActivityBind activitybind1 = new System.Workflow.ComponentModel.ActivityBind();

activitybind1.Name = "Workflow3"; //要绑定Activity对象实例的Name

activitybind1.Path = "S"; //要绑定的Activity对象属性

//进行绑定

this.activity11.SetBinding(Activity1.AProperty,activitybind1);

//移除绑定

//this.activity11.RemoveProperty(Activity1.AProperty);

<ns0:Activity1

x:Name="activity11"

A="{ActivityBind Workflow3,Path=S}"

B="wxwinter"

C="{x:Null}" />

绑定使用

 从属属性 = "{ActivityBind  要绑定Activity对象实例的Name,Path=要绑定的Activity对象属性 }"

不绑定，直接赋值

从属属性="值"

或

从属属性="{x:Null}"

也可以使用如下方式绑定

 <ns0:Activity1x:Name="activity11" B="wxwinter"C="{x:Null}" >

    <ns0:Activity1.A>

      <ActivityBindName="Workflow3"Path="S" />

    </ns0:Activity1.A>

 </ns0:Activity1
