Question

C#使用Timer控件使一张图片向下移动,求代码.谢谢各位大大,

是图片自动向下移动哦,

Answer 1

private int startX = 550;
private bool isAdd = false;
public Form1()
{
InitializeComponent();
}

private void picShow_Paint(object sender, PaintEventArgs e)
{
if (isAdd) {
startX += 20;
if (startX > picShow.Width) {
isAdd = false;
}
} else {
if (startX < 0) {
isAdd = true;
}
startX -= 20;
}
e.Graphics.DrawImage(imageList1.Images[0], new Point(startX, 0));
}

private void timer1_Tick(object sender, EventArgs e)
{
picShow.Refresh();
}

private void Form1_Load(object sender, EventArgs e)
{
timer1.Interval = 10;
timer1.Enabled = true;
}

这是以前写的，你把X和Y改一下不就行了？

Answer 2

在Timer控件的Tick事件中写上
int i = pictureBox1.Location.Y + 10;
pictureBox1.Location = new Point(pictureBox1.Location.X, i);
注意要设置Timer控件的Enabled属性为true
