Answer 3

关键代码：//测试通过
private void button5_Click(object sender, System.EventArgs e)
{
int iPB = 0;
foreach(System.Windows.Forms.Control c in this.Controls)
{
if(c is PictureBox)
{
iPB++;
}
}
PictureBox[] pbs = new PictureBox[iPB] ;
iPB = 0;
foreach(System.Windows.Forms.Control c in this.Controls)
{
if(c is PictureBox)
{
pbs[iPB] = (PictureBox)c;
iPB++;
}
}
}

Answer 4

for(int i = 0; i < this.Controls.Count; i++)
{
if(this.Controls[i] is PictureBox)
//加入数组
}

Answer 5

不如把数组修改成数组列表,那样方便些.
private void button5_Click(object sender, System.EventArgs e)
{
    ArrayList pics=new ArrayList();
    foreach(System.Windows.Forms.Control c in this.Controls)
    {
if(c is PictureBox)
    pics.Add(c);
    }
}
