How to create a StyleMap tag with SharpKml?

Question

I'd like to know how to create the following XML using SharpKml:

<StyleMap id="msn_placemark_circle">
    <Pair>
        <key>normal</key>
        <styleUrl>#sn_placemark_circle</styleUrl>
    </Pair>
    <Pair>
        <key>highlight</key>
        <styleUrl>#sh_placemark_circle_highlight</styleUrl>
    </Pair>
</StyleMap>

I've tried several things, but with no success. This is what I have so far:

public static StyleSelector Generate_M_ylw_pushpin3()
{
    var stylemap = new StyleMapCollection();
    stylemap.Id = "s_ylw-pushpin3";
    var normalPair = new Pair();
    normalPair.Id = "normal";
    normalPair.Selector = StyleGenerator.Generate_s_ylw_pushpin_hl3();
    //normalPair.StyleUrl = new Uri(#sh_placemark_circle_highlight); // Exception by .NET

    var highlightPair = new Pair();
    highlightPair.Id = "highlight";
    highlightPair.Selector = StyleGenerator.Generate_s_ylw_pushpin_hl3();
    //highlightPair.StyleUrl = new Uri(#sh_placemark_circle_highlight); // Exception by .NET

    stylemap.Add(normalPair);
    stylemap.Add(highlightPair);

    return stylemap;
}

// This code just works fine
public static StyleSelector Generate_s_ylw_pushpin_hl3()
{
    var style = new Style();
    style.Id = "s_ylw-pushpin_hl3";
    var iconStyle = new IconStyle();
    iconStyle.Color = Color32.Parse("ff00ff00");
    iconStyle.Scale = 1.18182;
    iconStyle.Icon = new IconStyle.IconLink(new Uri("http://some/url"));
    var labelStyle = new LabelStyle();
    labelStyle.Color = Color32.Parse("00ffffff");

    style.Icon = iconStyle;
    style.Label = labelStyle;

    return style;
}

Who knows on how to achieve this?

I've find the answer to my own question:

public static StyleSelector Generate_M_ylw_pushpin3()
{
    var stylemap = new StyleMapCollection();
    stylemap.Id = "s_ylw-pushpin3";
    var normalPair = new Pair();
    normalPair.StyleUrl = new Uri("#sh_placemark_circle", UriKind.Relative); 
    normalPair.State = StyleState.Normal;

    var highlightPair = new Pair();
    highlightPair.StyleUrl = new Uri("#sh_placemark_circle_highlight", UriKind.Relative); 
    highlightPair.State = StyleState.Highlight;

    stylemap.Add(normalPair);
    stylemap.Add(highlightPair);

    return stylemap;
}
