How to use the Selection.Item with C#?

[Byungchul Kang]

Hello, List.
Newbie question about Selection.Item with C#

I was wondering how i would pick a object from Selection, as below.
Anyone give a tip.

I want to


public bool Execute( Context in_ctxt )
{

Log("Execute called");

        XSIApplication si = GetXSI();
        Selection oSel = si.Selection;

        // Getting a first one of Selection
        X3DObject oneObj = (X3DObject)oSel.get_Item[0]; //Error line
        Log(oneObj.FullName);

        // Iterating a list of Selection
        foreach (X3DObject obj in oSel)
        {
            Log(obj.FullName);
        }
        return true;
}.

Thanks
Kang

p.s : Sorry my bad English.
