ComboBoxEdit' 不包含 'Items' 的定义

Question

我正在尝试 link ComboboxEdit with Database values.But 在编写代码时我的 VS 找不到元素 Item :

magazin.Items.Add(s);

它给了我这个错误：

ComboBoxEdit' does not contain a definition for 'Items' and no 'Items' extension method that accepts a first argument of type 'ComboBoxEdit' was found(is a directive using an assembly reference missing?

这是我的代码：

static string conString = ConfigurationManager.ConnectionStrings["cnxString"].ConnectionString;

public void fillCombo()
{
    ArticleDAL a = new ArticleDAL();

    string query = "select * from tbl_magazin;";
    SqlConnection cnx = new SqlConnection(conString);
    SqlCommand c = new SqlCommand(query, cnx);
    SqlDataReader r;
    try
    {
        cnx.Open();
        r = c.ExecuteReader();
        while (r.Read())
        {
            string s = r["libelle"].ToString();
            magazin.Items.Add(s);
        }
    }
    catch (Exception e)
    {}
    finally
    { }
}

正如评论中所建议的解决方案是使用：

comboBoxEdit.properties.items.add()

而不是

comboBoxEdit.Items.Add(s);

ComboBoxEdit' 不包含 'Items' 的定义
