本文介绍了如何从XML文件中读取数据绑定到DropDownList。

http://dev.csdn.net/author/hufengwen/f17ed0d5e48b4f418f07ff10a365e9a1.html

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：

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>日语</languageTextField>

</language>

</languageTypes>
