在我的应用程序中,我想在后台创建数千个文件,但是当我执行此操作时,它总是冻结我的表单(创建所有文件后,我可以再次使用我的表单)。如何在不挂起的情况下正常运行?
private void button5_Click(object sender, EventArgs e)
{
BackgroundWorker bw = new BackgroundWorker();
bw.WorkerReportsProgress = true;
bw.DoWork += new DoWorkEventHandler(
delegate(object o, DoWorkEventArgs args)
{
BackgroundWorker b = o as BackgroundWorker;
this.Invoke(new MethodInvoker(delegate
{
getValues();//load some text fields into strings
while (counter < counted)
{
text = richTextBox1.Text;
text = text.Replace("number", finalNumber);
//create copies
if (checkBox1.Checked == true)
{
while (createdCopies < copies)
{
createdCopies++;
File.WriteAllText(fileName, text);
overalCounter++;
b.ReportProgress(overalCounter);
}
counter++;
createdCopies = 0;
}
//dont create copies
else
{
File.WriteAllText(fileName, text);
counter++;
overalCounter++;
b.ReportProgress(overalCounter);
}
//info about number of files created
label6.Text = "created " + overalCounter.ToString() + " files";
}
label1.Text = "success";
}));
});
if (bw.IsBusy != true)
{
bw.RunWorkerAsync();
}
bw.ProgressChanged += new ProgressChangedEventHandler(
delegate(object o, ProgressChangedEventArgs args)
{
this.Text = string.Format("{0}% Completed", args.ProgressPercentage);
});
}
