asp.net实现XML文件读取数据绑定到DropDownList的方法
本文实例讲述了asp.net实现XML文件读取数据绑定到DropDownList的方法。分享给大家供大家参考，具体如下：
1、绑定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：
privateICollectioncreateDataSource()
{
//createadatatabletostorethedatafortheddl_langaugecontrol
DataTabledt=newDataTable();
//definethecolumnsofthetable
dt.Columns.Add("languageTextField",typeof(string));
dt.Columns.Add("languageValueField",typeof(string));
//readthecontentofthexmlfileintoaDataSet
DataSetlanDS=newDataSet();
stringfilePath=ConfigurationSettings.AppSettings["LanguageXmlFile"];
lanDS.ReadXml(filePath);
if(lanDS.Tables.Count>0)
{
foreach(DataRowcopyRowinlanDS.Tables[0].Rows)
{
dt.ImportRow(copyRow);
}
}
DataViewdv=newDataView(dt);
returndv;
}
3、Web.config
<appSettings> <!--Thefilepathforthelanguagetypexmlfile--> <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>日语</languageTextField> </language> </languageTypes>
