快速实现进度条

private void ShowProgress()
{
if (Worker._vProgress == null)
{
Worker._vProgress = new Progress();
Worker._vProgress.TotalCount = Worker.VLstDataTable.Count;
}

Worker._vProgress.OnProgressChanged += e => {
this.Invoke((MethodInvoker)delegate()
{
if (progressBar1.Value == 100) return;
progressBar1.Value = (int)(e.PostCount * 100 / e.TotalCount);
System.Diagnostics.Trace.WriteLine(string.Format("Progress:{0}",e.PostCount));
progressBar1.Refresh();
});
return e;
};
