怎样遍历页面上的DropDownlist？(急急急急)

[eminem346]

代码是这样的
private void getShip()
{
DataSet ds = CarrieDAL.CarrieQueryAll();
ddlship1.DataSource = ds;
ddlship1.DataTextField = ds.Tables[0].Columns["carriename"].ToString();
ddlship1.DataValueField = ds.Tables[0].Columns["carriename"].ToString();
ddlship1.DataBind();
ddlship2.DataSource = ds;
ddlship2.DataTextField = ds.Tables[0].Columns["carriename"].ToString();
ddlship2.DataValueField = ds.Tables[0].Columns["carriename"].ToString();
ddlship2.DataBind();

}
private void getShipName1(string carriename)
{
DataSet ds = CarrieDAL.getshipname(carriename, null);
ddlshipname1.DataSource = ds;
ddlshipname1.DataTextField = ds.Tables[0].Columns["shipname"].ToString();
ddlshipname1.DataValueField = ds.Tables[0].Columns["shipname"].ToString();
ddlshipname1.DataBind();

ds = CarrieDAL.getvoyages(ddlshipname1.SelectedValue);
ddlvoyages1.DataSource = ds;
ddlvoyages1.DataTextField = ds.Tables[0].Columns["voyages"].ToString();
ddlvoyages1.DataValueField = ds.Tables[0].Columns["voyages"].ToString();
ddlvoyages1.DataBind();

}
private void getShipName2(string carriename)
{
DataSet ds = CarrieDAL.getshipname(carriename, null);
//船名
ddlshipname2.DataSource = ds;
ddlshipname2.DataTextField = ds.Tables[0].Columns["shipname"].ToString();
ddlshipname2.DataValueField = ds.Tables[0].Columns["shipname"].ToString();
ddlshipname2.DataBind();

ds = CarrieDAL.getvoyages(ddlshipname2.SelectedValue);
ddlvoyages2.DataSource = ds;
ddlvoyages2.DataTextField = ds.Tables[0].Columns["voyages"].ToString();
ddlvoyages2.DataValueField = ds.Tables[0].Columns["voyages"].ToString();
ddlvoyages2.DataBind();
}
我的页面上有6个DropDownlist 但有两个两个邦定的数据是一样的 就是应为 DropDownlist的名字不同我邦定了6次
我想遍历一下 只让它邦定3次 请问各位大侠 这个怎么遍历？？

[hnyygy]

你这个本身就要分分开邦定，好像没有什么可以改的。
循环也要一个一个去判断，没有什么意思吧。

[编程有钱人了]

foreach (System.Windows.Forms.Control control in this.Controls) 
      { 
      bool iscontrol=false;
      if (control is System.Windows.Forms.DropDownlist) 
      { 
        System.Windows.Forms.DropDownlist tb = (System.Windows.Forms.DropDownlist)control ; 
          iscontrol=true;
         } 
      } 

[qingleo]

DataSet ds = CarrieDAL.getshipname(carriename, null);
DropDownList ddl=ddlshipname1;
ddl.DataSource = ds;
ddl.DataTextField = ds.Tables[0].Columns["shipname"].ToString();
ddl.DataValueField = ds.Tables[0].Columns["shipname"].ToString();
ddl.DataBind();

ds = CarrieDAL.getvoyages(ddlshipname1.SelectedValue);
ddl=ddlvoyages1;
ddl.DataSource = ds;
ddl.DataTextField = ds.Tables[0].Columns["voyages"].ToString();
ddl.DataValueField = ds.Tables[0].Columns["voyages"].ToString();
ddl.DataBind();

或者说这样，为了复制的方便

又发了一遍？

foreach(Control c in this.form1.Controls)
{
    if(c is DropDownList)
    {
        DropDownList ddl = c as DropDownList;
        if(ddl!=null && ddl.Name == "ddlshipname2")
        {
               //do whatever you want
        }
    }
}
