How do we access nested classes after loading the assembly ?

[rajshresta]

How do we access the nested class dynamically in .NET ? Basically I am using third party code (psn.disc assembly) to run few tasks and the requirement is to dynamically load the assembly at run-time.
Here is the code snippet:

namespace psn.disc
{
     public class discexec
     {
    public int name;
    public discsettings settings;
 
    public int Name
    {
                   get { return this.name; }         
      set { this.name = value; }
           }
 
    public discsettings Settings
    {
                   get { return this.settings; }         
      set { this.settings = value; }
           }    
 
     }
 
 
     public class discsettings
     {
           public int mode;
           public disccolor color;
 
           public disccolor Color
           {
                       get { return this.color; }         
           }
 
    public int Mode
    {
                  get { return this.mode; }         
      set { this.mode = value; }
           }
 
     }
 
 
     public class disccolor
     {
    List<string> colorval;
        public List<string> Add(string)
        {
            this.colorval.Add(string)
        }
     }
 
}
 
namespace digit.exec
{
   public class execclass
   {
 
    public void Execute()
        {
                AssemblyName asmbname = new Assemblyname();
        asmbname.Name = "psn.disc";
        asmbname.Culture = "";
        asmbname.Version = new Version(1,0,0,0);
        Assembly.Load(asmbname);
 
        Type classtype1 = asmbname.GetType("psn.disc.discsettings");
        Type classtype2 = asmbname.GetType("psn.disc.discexec");
 
        object obj1 = Activator.CreateInstance(classtype1);
        object obj2 = Activator.CreateInstance(classtype2);
 
        PropertyInfo name = classType2.GetProperty("Name");
        PropertyInfo exec = classType2.GetProperty("Settings");
 
        PropertyInfo mode = classType1.GetProperty("mode");
 
        mode.SetValue(obj1, 1, null);
 
        PropertyInfo settings = classType1.GetProperty("Color");
 
        }
     }
 
}

//How do I access the Add method within the disccolor
// class using settings property retrieved above so that I can update the list in the disccolor class ?

Include the psn.disc namespace in your new application.
This namespace has the disccolor class in it. Once you've included the namespace you will be able to access the disccolor and use it as you see fit. This will work because your disccolor is marked as Public. If it had been a Private class you would not be able to access it.

The problem is psn.disc assembly may or may not be present on the system. Hence I am loading the assembly at run-time and can not include the namespace in my application.
Thanks for your response.

Why can't you include it in your application?

[rajshresta]

I cannot include it in the application due to the following reasons:
If I add the third party assembly (psn.disc) reference in my application, then this assembly has to be in the GAC at run-time or I should package this assembly along with my application and load it to GAC. The first option is ruled of as this third party assembly may or may not be present in the GAC. The second option is ruled out too, as this assembly is dependent on many other assemblies and I cannot package everything.

As a result I am checking (is not implemented in the code) if the assembly is present and then loading it at run-time.
