1、现在只能显示头一个图片，我想让这个图片轮流循环显示。2、cj_counts字段默认值是5，当每次keys.Enter选中的那条记录的时候，这个值-1。当值=0的时候图片就不参加图片轮换不显示了。请问应该怎么写呢?100分求大侠帮忙。
if (e.KeyCode == Keys.Enter)
{
timer1.Enabled = false;
label1.Visible = true;
label1.Text = "恭喜您！抽中了：" + cj_names;
} private void timer1_Tick(object sender, EventArgs e)
{
string sql_str = "select * from cj_main";
SqlConnection conn = new SqlConnection(conn_str);
SqlCommand command = new SqlCommand(sql_str, conn);
conn.Open();
SqlDataReader rs = command.ExecuteReader();
if (rs.Read())
{
cj_names = rs["cj_names"].ToString();
cj_pic_path=rs["cj_pic_path"].ToString();
this.pictureBox1.Image=Image.FromFile(cj_pic_path);
}
if (e.KeyCode == Keys.Enter)
{
timer1.Enabled = false;
label1.Visible = true;
label1.Text = "恭喜您！抽中了：" + cj_names;
} private void timer1_Tick(object sender, EventArgs e)
{
string sql_str = "select * from cj_main";
SqlConnection conn = new SqlConnection(conn_str);
SqlCommand command = new SqlCommand(sql_str, conn);
conn.Open();
SqlDataReader rs = command.ExecuteReader();
if (rs.Read())
{
cj_names = rs["cj_names"].ToString();
cj_pic_path=rs["cj_pic_path"].ToString();
this.pictureBox1.Image=Image.FromFile(cj_pic_path);
}
