[解决办法]
int[] x = new int[6];
for (int i = 0; i < 6; i++)
{
Random ran = new Random();
x[i] = ran.Next(35);
}
string[] a = new string[6];
for (int i = 0; i < 6; i++)
{
a[i] = Convert.ToString(x[i]);
switch (x[i])
{
case 10: a[i] = "A"; break;
case 11: a[i] = "B"; break;
case 12: a[i] = "C"; break;
case 13: a[i] = "D"; break;
case 14: a[i] = "E"; break;
case 15: a[i] = "F"; break;
case 16: a[i] = "G"; break;
case 17: a[i] = "H"; break;
case 18: a[i] = "I"; break;
case 19: a[i] = "J"; break;
case 20: a[i] = "K"; break;
case 21: a[i] = "L"; break;
