The best way to use a property to reference a Key-Value pair in a dictionary

Question

This is a pretty trivial question, but I'm curious to hear the opinions of people on it.

If I have a dictionary that can be accessed through properties, which of these formats do you prefer for the property?

/// <summary>
/// This class FirstProperty property
/// </summary>
[DefaultValue("myValue")]
public string FirstProperty {
    get {
        return Dictionary["myKey"];
    }
    set {
        Dictionary["myKey"] = value;
    }

This is probably the typical way to do this. It is quite effective, easy to understand, etc. The only drawback is a longer or more complex key, which could seal or change only one instance or something else, which will lead me to this:

/// <summary>
/// This class SecondProperty property
/// </summary>
[DefaultValue("myValue")]
private const string DICT_MYKEY = "myKey"
public string SecondProperty {
    get {
        return Dictionary[DICT_MYKEY];
    }
    set {
        Dictionary[DICT_MYKEY] = value;
    }
