protected void Button4_Click(object sender, EventArgs e)
{
Thread thread = new Thread(new ThreadStart(dowork));
thread.Start();
}
public void dowork()
{
//Label1.Text = "开始线程";
int st1;
UInt32 Snr=0;
StringBuilder Data1 = new StringBuilder(10);
Data1.Length = 10;
while(true)
{
st1 = Cdll.rf_srd_eeprom(icdev1, 0, 1, Data1);
if (st1 != 0)
{
Lab1.Text = "故障或为初始化";
}
else
{
Lab1.Text = Data1.ToString();
st1 = Cdll.rf_reset(icdev1, 60);
st1 = Cdll.rf_card(icdev1, 1, ref Snr);
if (st1 != 0)
{
Lab3.Text = "寻卡失败";
}
else
{
Lab2.Text = "寻卡成功";
}
}
System.Threading.Thread.Sleep(2000);
}
结果运行时Lab1的内容可以正常显示，尔Lab2和Lab3却无法显示，请问是什么原因
