我想计算两个日期之间的差异,一个是从dateTimePicker1中挑选出来的,另一个是2014年2月20日,并将其存储在一个字符串中以添加到我的数组中,并能够以另一种形式显示

        public string dateString;
        public string differenceAsString;


        public Patient()
        {
            patientidString = "";
            firstNameString = "";
            lastNameString = "";
            dateString = "";
        }

    //Array
    Patient[] patientInfo = new Patient[10];




    private void button1_Click(object sender, EventArgs e)
    {
        TimeSpan difference = getDateDifference(new DateTime(2014, 2, …
