C#中构造函数重载的用法

public class LanguageConfiguration
{
        public LanguageConfiguration()
        {
            InitClass();
        }
        private void InitClass()
        {
            InitClass("LanguageConfigFile");
        }
        public LanguageConfiguration(string languageXml)
        {
            InitClass(languageXml);
        }

        private void InitClass(string languageXml)
        {

         }
}

用法
LanguageConfiguration lc = new LanguageConfiguration("OperationLanguageConfigFile");
