Using Generics to return a literal string or from Dictionary

Question

I think I outsmarted myself this time. Feel free to edit the title also I could not think of a good one.

I am reading from a file and then in that file will be a string

Answer 1

So here is the answer I came up with, I am a little worried about boxing and unboxing but it works for now

public class WorkContainer:Dictionary
{
    public T GetKeyValue(string Parameter) 
    {
        if (Parameter.StartsWith("[? "))
        {
            string key = Parameter.Replace("[? ", "").Replace(" ?]", "");

            if (this.ContainsKey(key))
            {
                if (typeof(T) == typeof(string) )
                {
                    // Special Case for String, especially if the object is a class
                    // Take the ToString Method not implicit conversion
                    return (T)Convert.ChangeType(this[key].ToString(), typeof(T));
                }
                else
                {
                    return (T)this[key];
                }
            }
            else
            {
                return default(T);
            }

        }
        else
        {                
            return (T)Convert.ChangeType(Parameter, typeof(T));
        }
    }
}
