求救高手指点...在F10下可以写出结果,,在F5下就不出来结果了啊...

一个单击时间.
private void button2_Click(object sender, EventArgs e)
{
Thread.Sleep(100);
Transmit();
}
上面调用此方法
public void Transmit()
{
Byte[] Send = new Byte[1];
Send[0] = 0xAA;
serialPort1.Write(Send, 0, 1);
Byte[] SendBy = new Byte[24];
byte Sum = 0;
SendBy[0] = 0x01;
SendBy[3] = 0x07;
for (int i = 0; i < 24; i++)
{
Sum = (byte)(SendBy[i] + Sum);
}
SendBy[23] = Sum;
this.serialPort1.Write(SendBy, 0, 24);
}
private void timer1_Tick(object sender, EventArgs e)
{
label2.Text = System.DateTime.Now.ToString("HH:mm:ss");
byte[] goor = new byte[serialPort1.BytesToRead];
serialPort1.Read(goor, 0, serialPort1.BytesToRead);
string boog = BitConverter.ToString(goor).Trim();
boog = boog.Replace("-", "");
Latestdata(boog);
}
public void Latestdata(string boog)
{
try
{
if (boog.Length > 4)
{
if (boog.Substring(0, 2) == "55")
{
string poor = boog.Substring(4, boog.Length - 4);
if (poor.Substring(18, 2) != "00")
{
poor = poor.Substring(14, 6).ToString();
textBox2.Text = poor;
}
else
{
poor = Convert.ToInt32(poor.Substring(14, 6), 16).ToString;
textBox2.Text = poor;
}
}
else if (boog.Substring(0, 2) == "FE")
{
string poor = boog.Substring(2, boog.Length - 2);
if (poor.Substring(18, 2) != "00")
{
poor = poor.Substring(14, 6).ToString();
textBox2.Text = poor;
}
else
{

textBox2.Text = poor;
}
}
}
}

timer1_Tick是不是根本没有运行到单击事件里...

[gaara777]

怎么没人知道???

[兔子-顾问]

Thread.Sleep(100);这句话
修改为：




Thread.Sleep(1000);
这样试试，或是
int tick = Environment.TickCount;
while(Environment.TickCount-tick<1000) Application.DoEvents();

好头大看得

[回忆是抓不到的月光]

对端口不熟，不过你可以看看是不是每次timer事件里面接收的数据都被刷新了，如果是这么的话，那么你就要考虑下读取机制了

[gaara777]

改过，，但是还是不行啊...是不是漏了什么???

[gaara777]

还是不行啊,,,

//=======================
timer1.Interval = 1000;
timer1.enable=false;
//=======================
Thread.Sleep(100);

[cactus123456]

想了想timer中的
//===================
while(serialPort1.BytesToRead==0)
{
Thread.Sleep(100);
}
//===================
应该去掉

[gaara777]

嘿嘿，,又是你啊，,怎么称呼...谢谢你啊,,,高手...感觉还是不行啊....

[cactus123456]

private void timer1_Tick(object sender, EventArgs e)
{
//F5运行前这一行放个断点
label2.Text = System.DateTime.Now.ToString("HH:mm:ss");

你F5运行，button2 按后，会断到断点处，然后再F10运行看看

[gaara777]

不行啊，,高手...那里放一个断点的话就会没有响应啊。...

[gaara777]

可以了啊，,自己搞好了啊。.要多睡下才可以啊..Thread.Sleep(5000);
