How to change property accessors on runtime

Question

I'm looking for a way to change / add accessors to properties of a given class on runtime. sample code bellow, runs on .ctor of the class, what I want to reach is to add the 'TheSetMethod' to 'set' accessor of each 'field' so by changing the field on runtime. FYI: There's an implementation constraint behind this that makes me do this in this way istead of using standard "get;set;" ancestors, so I can not have 'get;set;' in design time.

    public string field1;

    .ctor()
    {
        Type typeWebConfig = this.GetType();
        MemberInfo[] Fields = typeWebConfig.GetMembers(BindingFlags.Public |
                              BindingFlags.Instance );
        foreach(MemberInfo member in Fields) 
            if(member.MemberType == MemberTypes.Field)
            {
                FieldInfo field = (FieldInfo)member;
                //add a delegate method to field's 'SET'
            }
     }

     void TheSetMethod(string propName)
     {
     }

any help will be appreciated. Cheers

Answer 1

You could implement a custom DynamicObject type to handle the accessors manually. This will only work in .NET 4+ though.

Answer 2

Why not just add the code to the setters to start with and then use a variable to determine if the code should execute or not? This sounds like a poor design in my opinion as making the setter's "Dynamic" also seems like it will not be able to be tested very well.
