检查DependencyProperty已注册

Question

在我再次运行下面的代码之前，如何知道“Status”DependencyProperty是否已注册？

代码：

public readonly DependencyProperty StatusProperty ; 

    public string Status 
    { 
     get { return (string)GetValue(StatusProperty); } 
     set { SetValue(StatusProperty, value); } 
    } 

StatusProperty = DependencyProperty.Register("Status", typeof(string), typeof(CWindow), new PropertyMetadata());

你需要反思，找出那些已经注册的Depenedency属性。

using System.Reflection; 

foreach (FieldInfo fInfo in CWindow.GetType().GetFields()) 
{ 
    if (fInfo.FieldType.Name == "DependencyProperty") 
    { 
     if (fInfo.GetValue(null) == "Status") 
     { 
      Console.WriteLine("Status Property already Registered"); 
     } 
    } 
}
