class c_apostropheProcess      
    {
        string apostropheProcess ;

        public c_apostropheProcess(string apostrophe)
        {
            apostropheProcess = apostrophe;
        }

        public bool apostrophe_Proces()//这提示错误“managementStudents.c_apostropheProcess.apostrophe_Proces()”: 并非所有的代码路径都返回值        managementStudents

        {
            int i;

            for (i = 0; i < apostropheProcess.Length; i++)
            {
                if (apostropheProcess[i]=='a')
                {
                    return true;
                }
            }
        }

我真不知道怎么改了

要是我用这个方法查找单引号该怎么改阿

public bool apostrophe_Proces()
        {
            int i;

            for (i = 0;i<apostropheProcess.Length;i++)
            {
                if (apostropheProcess[i] == '\'')
                {
                    return false;
                }
            }
            return true;
        }

这样改对吗
