推薦：C#定時(shí)器的使用
C#定時(shí)器的使用以下為引用的內(nèi)容： Timer timer1; this.timer1.Interval = 1000; this.timer1.Tick = new System.Ev

1 、綁定DropDownList：

以下為引用的內(nèi)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：

以下為引用的內(nèi)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);
}
}

DataView dv = new DataView(dt);

return dv;
}

3、Web.config

以下為引用的內(nèi)容：
<appSettings>

<addkey="LanguageXmlFile"value="d:/Rhombussolution/Rhombus2/Languages.xml"/>
</appSettings>

4、Languages.xml

以下為引用的內(nèi)容：

<?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>

分享：.NET中加密與解密QueryString的方法
1.加密。Response.Redirect("DetailInfo.aspx?id=" Convert.ToBase64String(System.Text.Encoding.Default.GetBytes("sp10006")).Replace(" ","+"
