private void button1_Click(object sender, EventArgs e)
{
string strA;
int iLA = 0;
int iCount = 0;
strA = "X33A2E445G";
string strB;
iLA = strA.Length;
for (int i = 1; i < iLA; i++)
{
strB = strA.Substring(i, 1);
if (strB.CompareTo("G") <= 0 && strB.CompareTo("A") >= 0)
{
i = i + 1;
iCount = iCount + 1;
}
}
MessageBox.Show(Convert.ToChar(64 + iCount).ToString());
}
答案: C
