推荐答案

根据您的要求更改示例代码

Sample code change as per your requirement

bool m_flag = false;
DateTime dt = new DateTime(1983, 5, 1, 8, 30, 52);
        DateTime dt1 = DateTime.Now;
        string strDate = dt.ToString("M/dd/yyyy");
        string strDate1 = dt1.ToString("M/dd/yyyy");
        if (compareDates(Convert.ToDateTime(strDate1), Convert.ToDateTime(strDate)))
        {
            m_flag = true;
            Response.Write("Valid");
        }
        else
        {
            Response.Write("Invalid");
        }

<pre>public bool compareDates(DateTime dtHireDate, DateTime dtDateOfBirth)
    {
        int age = dtHireDate.Year - dtDateOfBirth.Year;
        if (dtHireDate.Month < dtDateOfBirth.Month || (dtHireDate.Month == dtDateOfBirth.Month && dtHireDate.Day < dtDateOfBirth.Day))
            age--;
        if (age >= 18)
        {
            m_flag = true;
        }
        else
        {
            m_flag = false;
        }
        return m_flag;
    }
