Getting all properties of an object

This might be closer to what you're looking for:

using System;
using System.Reflection;

class Test
{
    static void Main()
    {
       MyClass objA = new MyClass();
       ShowPropertyValue(objA, "Prop1", "Prop3", 42);
       Console.WriteLine();
       ShowPropertyValue(objA, "Prop2", "Prop4", "Goodbye");
       Console.ReadLine();
    }

    static void ShowPropertyValue(object objT, string prop1, string prop2, object newValue)
    {
       Type myType = objT.GetType(); //gets runtime type
       Console.WriteLine("objT is of type {0}", myType);
       BindingFlags bf = BindingFlags.Public | BindingFlags.Instance |
       BindingFlags.GetProperty;
       PropertyInfo prop1Info = myType.GetProperty(prop1, bf);
       if (prop1Info == null)
       {
          Console.WriteLine("There is no public instance property called {0} in the {1} type", prop1, myType);
          return;
       }
       object result = myType.InvokeMember(prop1, bf, null, objT, null);
       Type prop1Type = prop1Info.PropertyType;          
       PropertyInfo prop2Info = prop1Type.GetProperty(prop2, bf);
       if (prop2Info == null)
       {
          Console.WriteLine("There is no public instance property called {0} in the {1} type", prop2, prop1Type);
          return;
       }
       object result2 = prop1Type.InvokeMember(prop2, bf, null, result, null);
       Console.WriteLine("Value of objT.{0}.{1} is {2}", prop1, prop2, result2);
       prop2Info.SetValue(result, newValue, null);
       result2 = prop2Info.GetValue(result, null);
       Console.WriteLine("Value of objT.{0}.{1} is now {2}", prop1, prop2, result2);
    }
}

class MyClass
{

   YourClass yourClass = new YourClass();
   HisClass hisClass = new HisClass();
 
   public YourClass Prop1
   {
      get { return yourClass; }
      set { yourClass = value; }
   }

   public HisClass Prop2
   {
      get { return hisClass; }
      set { hisClass = value; }
   }

}

class YourClass
{
   int myInt = 3; // default value
  
   public int Prop3
   {
      get { return myInt; }
      set { myInt = value; }   
   }
}

class HisClass
{
   string myString = "Hello"; // default value
  
   public string Prop4
   {
      get { return myString; }
      set { myString = value; }
   }
}

That was really good !! But the actual issue is I dont Know about type of the object..ie it could be objA,objB means can be of any class.Lets suppose I have 3 classes A,B,C.

Now, I will know about the type of class only at run time..which i supposed in my original query as of class A.Then writing code like,

int value = (int)prop2Info.GetValue(objA.Prop1, null);......wud not be possible as I cannot dynamically write objA.Prop1 Since during design time I wud be having only object of type Object as

Object objT = new object() and not

  MyClass objA = new MyClass();

Hope I made you understand my problem.

Here's a quick example of how you can do this:

using System;
using System.Reflection;

class Test
{
    static void Main()
    {
       MyClass objA = new MyClass();
       Type myType = objA.GetType();

       PropertyInfo prop1Info = myType.GetProperty("Prop1");
       Type prop1Type = prop1Info.PropertyType;
   
       PropertyInfo prop2Info = prop1Type.GetProperty("Prop2");
       int value = (int)prop2Info.GetValue(objA.Prop1, null);
       Console.WriteLine("Value of Prop2 is {0}", value);
       prop2Info.SetValue(objA.Prop1, 42, null);
       value = (int)prop2Info.GetValue(objA.Prop1, null);
       Console.WriteLine("Value of Prop2 is now {0}", value);
       Console.ReadLine();
    }

}

class MyClass
{

   YourClass yourClass = new YourClass();
 
   public YourClass Prop1
   {
      get { return yourClass; }
      set { yourClass = value; }
   }
}

class YourClass
{
   int myInt = 3; // default value
  
   public int Prop2
   {
      get { return myInt; }
      set { myInt = value; }   
   }
}
