.NET通过Reflection获取私有财产

Question

I've the following scenario

Assebly A

public abstract class MyBaseEntity        
{   
    //Uncompleted method     
    public void addChild<T>(T child)
    {            

        try
        {                
            Type tInfo = this.GetType();
            PropertyInfo pInfo = tInfo.GetProperties(BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance).Where(p => p.PropertyType == typeof(ISet<T>)).FirstOrDefault();                
            MethodInfo mInfo = tInfo.GetMethod("Add");
            mInfo.Invoke(this, new object[] {child});
        }
        catch (Exception ex)
        {               
            throw ex;
        }
    }

}

Assembly B

 public class MyModel : MyBaseEntity
{
    public virtual int p1 { get; set; }
    public virtual int p2 { get; set; }
    public virtual DateTime p3 { get; set; }
    public virtual bool p4 { get; set; }
    private readonly ISet<MyModelChild> _p5;
    private readonly ISet<MyModelChild2> _p6;
    public virtual string p7 { get; set; }

    public MyModel()
    {
        this._p5 = new HashSet<MyModelChild>();
        this._p6 = new HashSet<MyModelChild2>();
    }

    public virtual IEnumerable<MyModelChild> P5
    {
        get { return _p5; }
    }

    public virtual IEnumerable<MyModelChild2> P6
    {
        get { return _p6; }
    }
}    

In the class MyBaseEntity I try to get the private ISet child and call the method "Add". I call the "addChild" method like

myObject.addChild<MyModelChild>(child);

but the GetProperties method doesn't extract the private property. It can extracts all the public properties but not the private.

Anyone can help me?

Thank you!

你引用的两个私有字段是字段，而不是属性，当然你不会用GetProperties找到它们（你可以使用GetFields ）。
