说明：
button1_Click：学会g.DrawString的一般使用格式
button2_Click：学会FontStyle枚举值
Regular 普通文本。
Bold 加粗文本。
Italic 倾斜文本。
Underline 带下划线的文本。
Strikeout 中间有直线通过的文本。
Font f6 = new Font("Times New Roman", 12, FontStyle.Underline | FontStyle.Bold | FontStyle.Italic | FontStyle.Strikeout);
要求了解按位“或”运算符（“|”）
button4_Click：字符串大小计算
MeasureString：测量用指定的 Font 对象绘制并用指定的 StringFormat 对象格式化的指定字符串
button5_Click：文字对齐方式
StringFormat sf = new StringFormat();
sf.Alignment = StringAlignment.Center;
sf.LineAlignment = StringAlignment.Center;
Near 指定文本靠近布局对齐。在左到右布局中，近端位置是左。在右到左布局中，近端位置是右。
Center 指定文本在布局矩形中居中对齐。
Far 指定文本远离布局矩形的原点位置对齐。在左到右布局中，远端位置是右。在右到左布局中，远端位置是左。
button6_Click：做文字竖直效果
button7_Click：表格效果
button8_Click：网格效果
button9_Click：查询系统已经安装的字体
Button10_Click：查询系统已经安装的字体的另一种写法
本人也在学习GDI+，写得比较简单，让高手见笑了。欢迎高手给我指点
