Is it possible to make dynamic structures in C#?

  • 772

I would like to know if it is possible to modify the members of a structure or class from a derived class (add or remove members dynamically)

public class Base 
{ 
    public struct MyStruct
    {
        public Type originalVar;
    }
    MyStruct myStruct;
}

public class Derivada : Base 
{ 
    public ModificaEnum()
   { 
         //algo asi sería genial
         MyStruct.Add(Type, nuevaVar);
         MyStruct.Remove(Type, originalVar);
    }

}
c#

    And what if you use classes that are made for that like the Dictionary? These allow you to add/update/remove any property (indexer in this case) without having to generate code at runtime:

    var data = new Dictionary<String,object>();
data.Add("nombre", "Martin");
data.Add("edad", 16);

int edad = (int)data["edad"];
Console.WriteLine(edad);

    There is also the type dynamicusing the class ExpandoObjectin c#:

    dynamic p = new ExpandoObject();
p.nombre = "Einer";
p.edad = 99;

Console.WriteLine(p.nombre);
Console.WriteLine(p.edad.GetType().Name); // Int32

    Generating properties at runtime is very expensive so you should avoid it. Remember that C# is a typed language and adding runtime type checking functionality to it can cost you.
