如何给DropDownList动态赋值？

Question

按照搜索出来的结果<%
string[] achDrives=Directory.GetLogicalDrives();int nNumOfDrives=achDrives.Length;for (int i=0;i<nNumOfDrives;i++)
    DropDownList1.SelectedValue = achDrives[i];    
%>生成的页面中DropDownList没有数据，这里应该怎么改？

Answer 1

应该是 DropDownList1.Items.Add吧

Answer 2

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            LoadDicFrameCode();
        }
    }    /// <summary>
    /// 绑定页面结构组成字典
    /// </summary>
    private void LoadDicFrameCode()
    {
        DicPagePartCodeBLL dicPagePartCodeBLL = new DicPagePartCodeBLL();
        ddl_DicPagePartCode.DataSource = dicPagePartCodeBLL.GetAllDicPagePartCodes();
        ddl_DicPagePartCode.DataValueField = "Id";
        ddl_DicPagePartCode.DataTextField = "FPagePartName";
        ddl_DicPagePartCode.DataBind();
    }
