本文實例講述了asp.net實現XML文件讀取數據綁定到DropDownList的方法。分享給大家供大家參考，具體如下：
1 、綁定DropDownList：
ddl_language.DataSource = createDataSource();ddl_language.DataTextField = "languageTextField";ddl_language.DataValueField = "languageValueField";ddl_language.DataBind();
2、上面用到的createDataSource()方法：
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); } } DataView dv = new DataView(dt); return dv;}3、Web.config
<appSettings> <!--The file path for the language type xml file--> <addkey="LanguageXmlFile"value="d:/Rhombussolution/Rhombus2/Languages.xml"/></appSettings>
4、Languages.xml
<?xmlversion="1.0"encoding="utf-8"?><languageTypes> <language> <languageValueField>en-US</languageValueField> <languageTextField>English</languageTextField> </language> <language> <languageValueField>zh-CN</languageValueField> <languageTextField>中文</languageTextField> </language> <language> <languageValueField>ja-JP</languageValueField> <languageTextField>日語</languageTextField> </language></languageTypes>
希望本文所述對大家asp.net程序設計有所幫助。
