Answer 1

string[] tmp = new string[]{"0"，"1"，"2"，"3"，.... ,"A","B"...};
                System.Random rd = new Random();
                string result = "";
                for(int i=0;i<4;i++)
                {
                    int aaa = rd.Next(36);
                    result += tmp[aaa];
                }

Answer 2

string[] s = new string[36]{"0","1","2","3","4"
   ,"5","6","7","8","9",

   ,"H","I","J","K","L"
   ,"M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"}; string result = "";
System.Random r = new Random();
for(int i = 0;i < 4; i ++)
{
result += s[r.Next(36)];
}

MessageBox.Show(result);
