asp.net – 如何在web.config中迭代自定义键？

是否可以在asp.net web.config文件中创建自己的自定义键并使用C#进行迭代？你是如何做到的(我在哪里放钥匙？什么格式？)？我有一个Intranet应用程序,它根据客户端的IP地址执行某些操作.我没想在代码隐藏文件中对它们进行硬编码,而是将它们放在web.config中并迭代它.这样我就可以在配置文件中添加或删除而无需重新编译所有内容.

我的密钥将有一个名称,IP地址,也许还有其他信息.

谢谢.

我认为这应该为你做…

这是在你的web.config中…

<configSections>
    <section name="DataBaseKeys" type="System.Configuration.NameValueFileSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
</configSections>
<DataBaseKeys>
    <!--Connection Strings for databases (or IP Addresses or whatever)-->
    <add key="dbCon1" value="Data Source=DbServerPath;Integrated Security=True;database=DbName1"/>
    <add key="dbCon2" value="Data Source=DbServerPath;Integrated Security=True;database=DbName1"/>
    <add key="dbCon3" value="Data Source=DbServerPath;Integrated Security=True;database=DbName1"/>
    <add key="dbCon4" value="Data Source=DbServerPath;Integrated Security=True;database=DbName1"/>
    <add key="dbCon5" value="Data Source=DbServerPath;Integrated Security=True;database=DbName1"/>  
</DataBaseKeys>

这是你的代码……

using System.Configuration;

using System.Collections.Specialized;

protected void Page_Load(object sender, EventArgs e)
{
    LoadDdls();
}

private void LoadDdls()
{
    NameValueCollection nvcDbKeys = GetDbKeys();

    //Loop through the collection       
    for (int i = 0; i < nvcDbKeys.Count; i++)
    {
        // "Keys" is the "key" - Get(int) is the "value"
        this.DropDownList1.Items.Add(new ListItem(nvcDbKeys.Keys[i], nvcDbKeys.Get(i)));
    }
}

private NameValueCollection GetDbKeys()
{
    //Declare a name value collection to store Database Key List from web.config
    NameValueCollection nvcDatabaseKeyList;
    nvcDatabaseKeyList = (NameValueCollection) ConfigurationManager.GetSection("DataBaseKeys");

    return nvcDatabaseKeyList;
}
