說明：

button1_Click：學會g.DrawString的一般使用格式 

button2_Click：學會FontStyle列舉值

Regular普通文字。

Bold 加粗文字。

Italic 傾斜文字。

Underline帶下劃線的文字。

Strikeout中間有直線通過的文字。

Font f6 = new Font("Times New Roman", 12, FontStyle.Underline | FontStyle.Bold | FontStyle.Italic | FontStyle.Strikeout);

要求瞭解按位“或”運算子（“|”）

button4_Click：字串大小計算

MeasureString：測量用指定的 Font 物件繪製並用指定的 StringFormat 物件格式化的指定字串

button5_Click：文字對齊方式

StringFormat sf = new StringFormat();

sf.Alignment = StringAlignment.Center;

sf.LineAlignment = StringAlignment.Center;

Near指定文字靠近佈局對齊。在左到右佈局中，近端位置是左。在右到左佈局中，近端位置是右。

Center指定文字在佈局矩形中居中對齊。

Far 指定文字遠離佈局矩形的原點位置對齊。在左到右佈局中，遠端位置是右。在右到左佈局中，遠端位置是左。

button6_Click：做文字豎直效果

button7_Click：表格效果

button8_Click：網格效果

button9_Click：查詢系統已經安裝的字型
