Immutable views of mutable types

Question

I have a project where I need to construct a fair amount of configuration data before I can execute a process. During the configuration stage, it\'s very convenient to have

Answer 1

How about:

struct Readonly
{
    private T _value;
    private bool _hasValue;

    public T Value
    {
        get
        {
            if (!_hasValue)
                throw new InvalidOperationException();
            return _value;
        }
        set
        {
            if (_hasValue)
                throw new InvalidOperationException();
            _value = value;
        }
    }
}


[DataContract]
public sealed class Configuration
{
    private Readonly _version;

    [DataMember]
    public string Version
    {
        get { return _version.Value; }
        set { _version.Value = value; }
    }
}

I called it Readonly but I'm not sure that's the best name for it though.
