Question

我有一个控制包含我习惯的依附财产像这样:

 public static readonly DependencyProperty MouseEnterColorProperty =
            DependencyProperty.Register("MouseEnterColor", typeof (Color), typeof (SCADAPolyline), new PropertyMetadata(default(Color)));

        public Color MouseEnterColor
        {
            get { return (Color) GetValue(MouseEnterColorProperty); }
            set { SetValue(MouseEnterColorProperty, value); }
        }

它奇怪的问题。我正用反射来获取我的财产以设定新的价值。但无法获取我的财产。我尝试了所有可能的类型。 Get Fields ()

 FieldInfo fieldInfo = type.GetField(name, BindingFlags.FlattenHierarchy | BindingFlags.Public | BindingFlags.Static);

or 

 fieldInfo = type.GetFields(BindingFlags.Static | BindingFlags.Public)
                                          .Where(p => p.FieldType.Equals(typeof(DependencyProperty)) && p.Name==name).FirstOrDefault();

sounds like my property is missing.I cant access and this problem makes me so angry. How can i solve this problem any ideas? I am using silverlight 5.0

抚养财产不是字段,不是通常意义上的类别定义的一部分。

在幕后,它存储在一系列的依附财产中。

            return properties;
        }
