ToolStripStatusLabel控件的Image属性
public virtual Image Image { get;set; }

private void Form1_Load(object sender, EventArgs e)
{
int i = 1;
string str="";
Thread th = new Thread(
() =>
{
while(true)
{
Invoke((MethodInvoker)(() =>
{
toolStripStatusLabel1.Image =
Image.FromFile((++i>9?(i=1):i).ToString()+".bmp");
}));
Thread.Sleep(100);
}
});
th.IsBackground = true;
th.Start();
}
