namespace WindowsFormsApplication31
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        string[] major, course1, course2, course3, course4, course5;
        string gr, xy, msg;
        private bool checkGR()
        {
            bool check = true;
            if (txtAge.Text.Trim() == "" || txtName.Text.Trim() == "")
            {
                check = false;
                MessageBox.Show("姓名和年龄必须填写！");
            }
            return check;      
        }
        private string record
        {
            gr ="";                              //这个地方提示A get or set accessor excpted  后面就一直不能缩进 我也不知道哪里错了 求助啊
            gr += txtName.Text.Trim();
            if (radMale.checked)
             gr += ",男,";
            else
            gr+=",女，";
            gr+=""
        }
    }
}
