Estoy tratando de obtener los valores de los objetos dentro de una lista que es parte de un objeto principal.

Tengo el objeto principal que contiene varias propiedades que pueden ser colecciones.

En este momento estoy tratando de averiguar cómo acceder a una lista genérica que está contenida en el objeto.

///<summary>
///Code for the inner class
///</summary>
public class TheClass
{
    public TheClass();

    string TheValue { get; set; }
} //Note this class is used for serialization so it won't compile as-is

///<summary>
///Code for the main class
///</summary>
public class MainClass
{
    public MainClass();

    public List<TheClass> TheList { get; set; }
    public string SomeOtherProperty { get; set; }
    public Class SomeOtherClass { get; set }
}


public List<MainClass> CompareTheValue(List<object> MyObjects, string ValueToCompare)
{ 
    //I have the object deserialised as a list
    var ObjectsToReturn = new List<MainClass>();
    foreach(var mObject in MyObjects)
    {

        //Gets the properties
        PropertyInfo piTheList = mObject.GetType().GetProperty("TheList");

        object oTheList = piTheList.GetValue(MyObject, null);


        //Now that I have the list object I extract the inner class 
        //and get the value of the property I want
        PropertyInfo piTheValue = oTheList.PropertyType
                                          .GetGenericArguments()[0]
                                          .GetProperty("TheValue");

        //get the TheValue out of the TheList and compare it for equality with
        //ValueToCompare
        //if it matches then add to a list to be returned

        //Eventually I will write a Linq query to go through the list to do the comparison.
        ObjectsToReturn.Add(objectsToReturn);

    }
return ObjectsToReturn;
}

He intentado usar unSetValue() con MyObject en esto, pero falla con (parafraseado):

el objeto no es de tipo

private bool isCollection(PropertyInfo p)
{
    try
    {
        var t = p.PropertyType.GetGenericTypeDefinition();
        return typeof(Collection<>).IsAssignableFrom(t) ||
               typeof(Collection).IsAssignableFrom(t);
    }
    catch
    {
        return false;
    }
    }
}
