C# winApp จะแก้ตัวเลขยกกำลังแบบใหญ่บ้าง เล็กบ้าง ให้มีขนาดเท่ากันได้ยังไง บ้างครับ
Code (C#)

do

digits.Push(digit);
@this /= 10;
} while (@this != 0);
while (digits.Count > 0)
{
var digit = digits.Pop();
sb.Append(superscripts[digit]);
}
return sb.ToString();

ผมลองไล่ดูตั้งแต่ 0-10 แล้วได้แบบนี้ ครับ
Code (C#)
string ToSuperScript( int number)
{
if (number == 0 ||
number == 1)
return "";
const string SuperscriptDigits =
"\u2070\u00b9\u00b2\u00b3\u2074\u2075\u2076\u2077\u2078\u2079";
string Superscript = "";
if (number < 0)
{
//Adds superscript minus
Superscript = ((char)0x207B).ToString();
number *= -1;
}
Superscript += new string(number.ToString()
.Select(x => SuperscriptDigits[x - '0'])
.ToArray()
);
return Superscript;
}
Code (C#)
private void Form1_Paint(object sender, PaintEventArgs e)
{
int y = 30;
string s = "";
for (int i = 0; i < 10; i++)
{
s = "";
for (int a = 0; a < 11; a++)
{
s +=a + ToSuperScript(i) + ",";
}
e.Graphics.DrawString(s, new Font("Cordia New", 20), new SolidBrush(Color.Black), 50, y + (35 * i));
}
}
