I am trying to iterate an array while using backgroundworker, I am sure it is just my syntax being incorrect, but I am constantly getting the error. Can someone assist me with what to do to rectify this?
namespace Form1
{
public partial class Form1 : Form
{
public BackgroundWorker backgroundWorker1 = new BackgroundWorker();
public OpenFileDialog fd = new OpenFileDialog();
public Form1()
{
InitializeComponent();
backgroundWorker1.WorkerReportsProgress = true;
backgroundWorker1.WorkerSupportsCancellation = true;
backgroundWorker1.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);
backgroundWorker1.ProgressChanged += new ProgressChangedEventHandler(backgroundWorker1_ProgressChanged);
}
private void btn_Two_Click(object sender, EventArgs e)
{
fd.Title = "Select The Text File To Open";
fd.Filter = "Text Files|*.txt";
fd.InitialDirectory = @"C:\";
if (fd.ShowDialog() == DialogResult.OK)
{
TextFiles(sender);
}
}
private void TextFiles(object sender)
{
IEnumerable<String> employeeNames = File.ReadLines(fd.FileName);
foreach (string pgs in employeeNames)
{
employee = pgs;
ProcessTables(employee, sender);
}
}
private void ProcessTables(string employee, object sender)
{
sw.Restart();
timer.Start();
//This line is where the compiler throws the error
backgroundWorker1.RunWorkerAsync();
}
private void backgroundworker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
progressBar1.Value = e.ProgressPercentage;
}
private void backgroundworker1_DoWork(object sender, DoWorkEventArgs e)
{
//Never hits this block so I will omit this code for time sake
}
}
}
ProcessTables
is called in a loop by TextFiles
. So you're trying to restart a running BackgroundWorker
.
How to solve this, depends on what you're actually trying to do (you could prepare a "todo list" for a single BackgroundWorker
, use multiple BackgroundWorker
s, use producer/consumer pattern).
