泛型list綁定dropdownlist控件

定義類Ks 中讀寫屬性

private int _kid;
    public int kid
    {
        get { return _kid; }
        set { _kid = value; }
    }

    private string _kname;
    public string kname
    {
        get { return _kname; }
        set { _kname = value; }
    }

    private string _kperson;
    public string kperson
    {
        get { return _kperson; }
        set { _kperson = value; }
    }

定義獲取整個表的函數

public List<Ks> SelectList(int id)
    {
        string strSql = "select * from 科室表 ";
        if (id > 0)
        {
            strSql += " where 編號=" + id;
        }
        DataTable objDataTable = StaticValue.SelectTable(strSql);
        //new SQLHelper().ExecuteSql(strSql, out objDataTable);
        List<Ks> lstKs = new List<Ks>();
        foreach (DataRow row in objDataTable.Rows)
        {
            Ks objKs = new Ks();
            objKs.kid = int.Parse(row["編號"].ToString());
            objKs.kname = row["科室名稱"].ToString();
            objKs.kperson = row["科室負責人"].ToString();
            lstKs.Add(objKs);
        }
        return lstKs;
    }

初始化加載事件中使用（在web中）

protected void Page_Load(object sender, EventArgs e)
    {
        List<Ks> lstKs = new Ks().SelectList(0);
        this.szks.DataSource = lstKs;
        this.szks.DataValueField = "kid";
        this.szks.DataTextField = "kname";
        this.szks.DataBind();
    }

初始化加載事件中使用（在c# WindowsForm中）
private void LoadKs()
    { 

       List<Ks> lstKs = new Ks().SelectList(0);
       this.szks.DataSource = lstKs;
       this.szks.ValueMember = "kid";
       this.szks.DataTextField = "kname";

       this.cboLevel.SelectedIndex = 0;
