Problem getting the selected OBJECT object from the drop down list

Question

I have a problem with selecting the selected object from my list.

I associate a collection of users with a drop down list:

 ddlContractors.DataSource = service.GetAllUsers();
                ddlContractors.DataTextField = "Name";
                ddlContractors.DataValueField = "Id";
                ddlContractors.DataBind();

He works. But when I try to get the selected object:

var user = (User)ddlContractors.SelectedItem;

I get:

    (User)ddlContractors.SelectedItem   Cannot convert type 'System.Web.UI.WebControls.ListItem' to 'GWDSite.GWDService.User'

How can I get an object user from a drop down list? I can change the type of the list control if necessary
