public delegate void FileEventHandler(string file);
public event FileEventHandler fileEvent;
public void getAllFiles(string path)
{
foreach (string item in Directory.GetDirectories(path))
{
try
{
getAllFiles(item);
}
catch (Exception)
{ }
}
foreach (string str in Directory.GetFiles(path, "*.pcap"))
{
// process my file and if this file format OK raised event to UI and add the file to my listbox
FileChecker fileChecker = new FileChecker();
string result = fileChecker.checkFIle(str);
if (result != null)
fileEvent(result);
}
}
private void btnAddDirInput_Click(object sender, EventArgs e)
{
ThreadStart ts = delegate { getAllFiles(pathToSearch); };
Thread thread = new Thread(ts);
thread.IsBackground = true;
thread.Start();
}
我想等到线程完成它的工作然后更新我的 UI
最佳答案
您可以使用任务并行库(而不是显式任务)以及异步语言功能来非常轻松地完成此任务:
private async void btnAddDirInput_Click(object sender, EventArgs e)
{
await Task.Run(() => getAllFiles(pathToSearch));
lable1.Text = "all done!";
}
关于c# - 等到我的线程结束,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/18513205/
