フォルダ内にあるすべての設定ファイル（サブフォルダを含む）からConnectionstringを読み取るアプリを開発したかったのです。私はこのための勝利フォームアプリを開発しました。

 private void btnConnString_Click(object sender, EventArgs e)
 {
     var files = Directory.GetFiles(
         this.txtPath.Text.Trim(), 
         "*.config", 
         SearchOption.AllDirectories);
     foreach (string filepath in files)
     {
         string fileName;
         fileName = Path.GetFileName(filepath);
     } 
 }

次に、接続文字列を読み取る必要があります。どのようにできるのか？

このアプローチを試す必要があります。

ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
configMap.ExeConfigFilename = fileName;
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);
string connString =  config.ConnectionStrings.ConnectionStrings["ConnectionName"];

ホープ・ヘルプズ！
