Answer 1

We can follow these steps to retrieve the value of a collection class:

1)   Verify that the object is a generic type object.

if (myList.GetType().IsGenericType)

 

2)   Retrieve the Count property to determine the elements quantity of the list.   

int n = (int)myList.GetType().GetProperty("Count").GetValue(myList, null);

 

3)   Use a loop to call GetValue() on each element in the generic type object.

 

// Process each element in the list   

for (int i = 0; i < n; i++)

{

    // Get the list element as type object   

    object[] index = { i };

object myObject = myList.GetType().GetProperty("Item").GetValue(myList, index);

}

Answer 2

Introduction and Reference:

The common language runtime loader manages application domains, which are constituent defined boundaries around objects that have the same application scope.  This management includes loading each assembly into the appropriate application domain and controlling the memory layout of the type hierarchy within each assembly.

Assemblies contain modules, modules contain types, and types contain members.  Reflection provides objects that encapsulate assemblies, modules, and types.  You can use reflection to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object.  You can then invoke the type’s methods or access its fields and properties.
