ASP.NET Repeater Control & Array Index

I have a working repeater control filled by an array. I have added a delete button, but am unsure how to reference the array index in the Command Argument to pass to the delete command.

<asp:Repeater ID="gvRC" runat="server">
  ...
 <ItemTemplate>
      <li><%#Container.DataItem %>&nbsp;<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/images/icon_delete.gif" CommandName="deleteStation"  CommandArgument=" "  /></li>
 ...
</asp:Repeater>

The repeater is filled with a simple array by:
gvRC.DataSource = aryRC
gvRC.DataBind()

The index of the item is already included in the RepeaterCommandEventArgs argument of the ItemCommand event.

My code behind example is included below.  e.Item.ItemIndex contains the index of the item clicked.
 private List<string> DataSource
    {
        get
        {
            if (ViewState["DATASOURCE"] == null)
                this.DataSource = new List<string>(new string[] { "Hello", "World", "Good Bye", "Sanity" });
            return (List<string>)ViewState["DATASOURCE"];
        }
        set
        {
            ViewState["DATASOURCE"] = value;
        }
    }
 
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            this.Repeater1.DataSource = DataSource;
            this.Repeater1.DataBind();
        }
    }
 
    protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        if (e.CommandName.Equals("deleteStation"))
        {
            this.DataSource.RemoveAt(e.Item.ItemIndex);
            this.Repeater1.DataSource = DataSource;
            this.Repeater1.DataBind();
        }
    }

Perfect, Thank You. I figured it must be something simple like that.
