，自定义类的实现

求助，自定义类的实现
之前发了个帖子，但好像没表达清楚
一般操作app.config的connectionString的方法：
ConfigurationManager.ConnectionStrings["myName"].ConnectionString
ConfigurationManager.ConnectionStrings["myName"].Name
ConfigurationManager.ConnectionStrings["myName"].providerName

现在要实现一个自定义类 class CFM 达到与ConfigurationManager同样的效果
CFM.ConnStrs["myName"].ConnStr
CFM.ConnStrs["myName"].Name
CFM.ConnStrs["myName"].Prov

怎么写
[解决办法]
ConnStrs定义为ConnectionStringSettingsCollection 类型

看msdn ConnectionStringSettingsCollection 的说明



static void ShowConnectionStrings()
{
     // Get the application configuration file.
    System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);

    // Get the conectionStrings section.
    ConnectionStringsSection csSection =
        config.ConnectionStrings;

    for (int i = 0; i &lt; 
        ConfigurationManager.ConnectionStrings.Count; i++)
    {
        ConnectionStringSettings cs = 
            csSection.ConnectionStrings[i];

        Console.WriteLine("  Connection String: \"{0}\"",
            cs.ConnectionString);

        Console.WriteLine("#{0}", i);
        Console.WriteLine("  Name: {0}", cs.Name);


        Console.WriteLine("  Provider Name: {0}", 
            cs.ProviderName);

    }

}

鉴于你总是无满意结贴，就不给具体回答了。

定义一个叫ConnStrs的Dictionary<string, ConnectionStringSettings>就可以了。再不懂自己学学基本语法！
[解决办法]
app.config是个xml，你自己自定义的类做到解析xml不就可以了吗
