.NET Yansıma: Dinamik Özellikler alınamıyor Dinamik özellikler

Question

Yansıma yardımıyla bir sınıfa dinamik özellik ekliyorum. Ancak yeni/dinamik özellikler bulamıyor.

Süreci: Ben burada bütün manipülasyon özelliklerini güncellenmesini vermedi ama çalışmıyor ICustomTypeDescriptor Arayüzü uygulayarak bir DynamicClass oluşturulan ve fonksiyon GetPropertiesI uygulayan var ..

Benim DynamicClass kodu burada :

Answer 1

bir nesnenin çalışma özellikleri almak için

public class DynamicClass : ICustomTypeDescriptor 
{ 
    // Collection to code add dynamic properties 
    /* 
    KeyedCollection<string, DynamicProperty> _properties; 
    public KeyedCollection<string, DynamicProperty> Properties 
    { 
     get;// { return _properties; } 
     set;// { _properties = value; } 
    } 
    */ 
    public void AddProperty(DynamicProperty _property) 
    { 
     PropertyInfo[] instanceProps = this.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance); 

    // Fill property collection with founded properties 
    PropertyDescriptorCollection propsCollection = 
     new PropertyDescriptorCollection(instanceProps.Cast<PropertyDescriptor>().ToArray()); 

    propsCollection.Add(new DynamicPropertyDescriptor(
     _property.ComponentType, 
     _property.PropertyName, 
     _property.PropertyType, 
     _property.Component, 
     _property.Value

    // Fill property collection with founded properties 
    PropertyDescriptorCollection propsCollection = 
     new PropertyDescriptorCollection(instanceProps.Cast<PropertyDescriptor>().ToArray()); 

    foreach (var p in _properties) 
    { 
     propsCollection.Add(new DynamicPropertyDescriptor(
      p.ComponentType,

      p.PropertyType, 
      p.Component, 
      p.Value
