参考下
之前弄过的稍微改了下，你看看是不是这样。
整个Form就加了个Button控件，改名“获取验证”。
public partial class Form1 : Form{
System.Timers.Timer reGetTimer = new System.Timers.Timer()
public static int Times = 1
public Form1()
{
InitializeComponent()
reGetTimer.Elapsed += ReGetTimer_Elapsed
reGetTimer.Interval = 1000
reGetTimer.Enabled = false
}
private void ReGetTimer_Elapsed(object sender, ElapsedEventArgs e)
{
if (Times <= 10)
{
this.Invoke(new EventHandler(delegate { 获取验证.Text = Times.ToString()}))
Times++
}
else
{
reGetTimer.Enabled = false
Times = 1
this.Invoke(new EventHandler(delegate { 获取验证.Text = "重新获取" }))
}
}
private void 获取验证_Click(object sender, EventArgs e)
{
reGetTimer.Enabled = true
}
}
