下拉設置爲System.Data.DataRow，我的代碼出了什麼問題？

Question

System.Data.DataTable dt = new System.Data.DataTable(); 
    CDbAccess db = new CDbAccess(); 
    IDbConnection conn = db.GetConnectionInterface(); 
    conn.Open(); 
    string str = "select eName from bt_modules"; 
    IDbCommand cmd = db.GetCommandInterface(str); 
    IDbDataAdapter da = db.GetDataAdapterInterface(cmd); 
    da.SelectCommand = cmd; 
    DataSet ds = new DataSet(); 
    da.Fill(ds); 
    dt = ds.Tables[0]; 
    DropDownList2.DataSource = dt; 
    DropDownList2.DataBind(); 
    conn.Close(); 

上面的代碼設置下拉項目爲System.Data.DataRow

如何獲得的實際值？

Answer 1

嘗試這樣的：

DropDownList2.DataSource = dt; 
DropDownList1.DataTextField = "eName " '// Column Name 
DropDownList2.DataBind(); 

如果你想使用值字段也使用這樣

DropDownList2.DataSource = dt; 
DropDownList1.DataTextField = "eName " '// Column Name 
DropDownList1.DataValueField = "eid" '// Column Name 
DropDownList2.DataBind(); 

Answer 2

DropDownList2.DataSource = ds;

DropDownList2.DataTextField = "eName";

DropDownList2.DataBind();

conn.close();

你可以參考這個代碼也http://www.aspdotnet-suresh.com/2012/10/showbind-data-to-aspnet-dropdownlist.html
