如何从用户控件访问默认设置?

当我使用这个代码

时
namespace SearchControl{
public partial class SearchControl : UserControl   
{
     string ConncStr = Properties.Settings["myConnectionString"].toString();
}}

not working 

Properties.Settings["myConnectionString"].toString()

我想访问属性。设置("myConnectionString")

如何从用户控件访问默认设置

var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var secGroup = config.SectionGroups["userSettings"]; // or applicationSettings
if (secGroup != null)
{
    var clientSettings = (ClientSettingsSection)secGroup.Sections[0];
    var settingElementCollection = clientSettings.Settings;
    var setting = settingElementCollection.Get(Name);
    var value = setting.Value.ValueXml.InnerText;
}

string conStr = Properties.Settings.Default.myConnectionString;

大多数语句以;而不是}结尾

namespace SearchControl;
public partial class SearchControl : UserControl   
{
 string ConncStr = Properties.Settings.Default.myConnectionString;
}
