这是继学习Java和VB.NET后，对C#的一次突击学习，以十二星座为项目案例进行训练。

因为不太会用C#相对路径，所以比较粗暴的选了直接路径
核心代码：
private void monthCalendar1_DateChanged(object sender, DateRangeEventArgs e)
{
int month = monthCalendar1.SelectionStart.Month;
int day = monthCalendar1.SelectionStart.Day;
judgeConstellation(month, day);
}
private void judgeConstellation(int month, int day)
{
String[] starArr = {"魔羯座","水瓶座", "双鱼座", "白羊座", "金牛座", "双子座", "巨蟹座", "狮子座", "处女座", "天秤座", "天蝎座", "射手座" };
int[] dayArr = { 22, 20, 19, 21, 21, 21, 22, 23, 23, 23, 23, 22 };
int number = (month + 10) % 12;
int index = month;
if (day < dayArr[index-1])
{
number = (number + 11) % 12;
index = index - 1;
}
if (number == 0)
{
number = 12;
}
label1.Text = starArr[index];
pictureBox2.ImageLocation = "D:\\VisualBasic\\CSharpFrameworkTest\\CSharpFrameworkTest\\images\\" + number + ".png";
}完事儿！奈斯奈斯！
