12行: 最好不要在非UI的類別宣告UI會使用到的東西
16行: 盡量不要在同一行宣告兩個變數(即使那兩個變數被使用的性質很相近)
gcd在這邊是一個方法,所以名稱最好用全大寫的GCD,配上一個動詞會更好,如: GetGCD

第二題Form1.cs, 51行開始：
txtMessage.AppendText(MyDate.year + "/" + MyDate.month + "/" + MyDate.day + "是星期日 \n");
這些輸出字串的部分，可以在switch前就先設定前面不需要藉由switch判斷的字串。
Ex:
string message;
message = MyDate.year.ToString() + "/" + MyDate.month.ToString() + "/" + MyDate.day.ToString();
switch(MyDate.WeekDay())
{
case1:
message += "是星期一"
break;
...
}
