我的应用程序包含我要添加文件的列表框，当我使用添加文件夹执行此操作时，它会检查此文件夹中的所有文件，并通过在每个文件上打开不同的线程然后将这些文件添加到列表框中来完成 - 所以我应该使用锁定以防止 2 个（或更多）文件同时尝试添加文件？
private void btnAddDir_Click_1(object sender, EventArgs e)
{
int totalCount = 0;
int count = 0;
string fileToAdd = string.Empty;
List<string> filesList = new List<string>();
BackgroundWorker backgroundWorker = null;
DialogResult dialog = folderBrowserDialog1.ShowDialog();
if (dialog == DialogResult.OK)
{
btnAddfiles.Enabled = false;
btnAddDir.Enabled = false;
btnPlay.Enabled = false;
Editcap editcap = new Editcap();
foreach (string file in SafeFileEnumerator.EnumerateFiles(folderBrowserDialog1.SelectedPath, "*.*", SearchOption.AllDirectories))
{
if (editcap.isWiresharkFormat(file))
{
filesList.Add(file);
totalCount++;
}
}
backgroundWorker = new BackgroundWorker();
backgroundWorker.WorkerReportsProgress = true;
backgroundWorker.DoWork +=
(s1, e1) =>
{
foreach (string fileName in filesList)
{
if (editcap.isWiresharkFormat(fileName))
{
if (editcap.isLibpcapFormat(fileName))
{
backgroundWorker.ReportProgress(0, fileName);
count++;
}
else if (!editcap.isLibpcapFormat(fileName))
{
fileToAdd = editcap.getNewFileName(fileName);
if (new FileInfo(fileToAdd).Exists)
{
backgroundWorker.ReportProgress(0, fileToAdd);
count++;
}
}
this.Invoke((MethodInvoker)delegate
{
labelStatus.Text = string.Format("Please wait..({0}/{1} files were added)", count.ToString("#,##0"), totalCount.ToString("#,##0"));
if(listBoxFiles.Items.Count != 0)
listBoxFiles.SetSelected(listBoxFiles.Items.Count - 1, true);
});
}
}
};
backgroundWorker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(
(s1, e1) =>
{
});
backgroundWorker.ProgressChanged +=
(s1, arguments) =>
{
listBoxFiles.Items.Add(arguments.UserState);
};
backgroundWorker.RunWorkerAsync();
}
}
