如果(listBox1.Items.Count> = 7)
{
字符串路径= @"C:\ data.txt";
StreamWriter sw =新的StreamWriter(path);

Thread.Sleep(200);
for(int i = 0; i< listBox1.Items.Count; i ++)
{
sw.WriteLine(m_strTagUID);
listBox1.Items.RemoveAt(0);
}
sw.Close();
sw.Dispose();

}

{
string path = @"C:\data.txt";
StreamWriter sw = new StreamWriter(path);

Thread.Sleep(200);

{
sw.WriteLine(m_strTagUID);
listBox1.Items.RemoveAt(0);
}
sw.Close();
sw.Dispose();

}

推荐答案

我发现您的问题不清楚，但是如果您想每2秒执行一次操作，则需要使用计时器，那么您编写的代码只会停止执行该代码持续2秒钟.
对于更具可读性的代码，请使用此

I found your question not clear but if you want to execute something every 2 seconds you need to use a timer , the code you wrote just stop executing the code for 2 seconds.
and for more readable code use this

using (StreamWriter sw = new StreamWriter(path))
{
}
//here the the stream will close and dispose automatically 

希望我能帮上忙

hope that i could help
