1 、绑定DropDownList:

   

以下为引用的内容:
ddl_language.DataSource = createDataSource();
    ddl_language.DataTextField = "languageTextField";
    ddl_language.DataValueField = "languageValueField";
    ddl_language.DataBind();

2、上面用到的createDataSource()方法: 

以下为引用的内容:
 private ICollection createDataSource()
            {
                  //create a data table to store the data for the ddl_langauge control
                  DataTable dt = new DataTable();
 
                  //define the columns of the table
                  dt.Columns.Add("languageTextField",typeof(string));
                  dt.Columns.Add("languageValueField",typeof(string));
 
                  //read the content of the xml file into a DataSet
                  DataSet lanDS = new DataSet();
                  string filePath = ConfigurationSettings.AppSettings["LanguageXmlFile"];
                  lanDS.ReadXml(filePath);
 
                  if(lanDS.Tables.Count > 0)
                  {
                              foreach(DataRow copyRow in lanDS.Tables[0].Rows)
                              {
                                    dt.ImportRow(copyRow);
                            }
                  }
