C#中的BackgroundWorker控件+Delegate.Invoke （委托同步调用）

简单代码，记录一下。一个BackgroundWorker控件 backgroundWorkerRefresh +listview控件

using System;

using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;

namespace CallCenter
{
public partial class MainFrm : Form
{
public bool isStart = false;
public MainFrm()
{
InitializeComponent();
RefreshDisp();
}
private void RefreshDisp()
{
lv.Items.Clear();

for (int i = 0; i < 8; i++)
{
ListViewItem lvitem = new ListViewItem();
lvitem.SubItems[0].Text = i.ToString();
lvitem.SubItems.Add("项目编号" + i.ToString());
lvitem.SubItems.Add("项目名称" + i.ToString());
lvitem.SubItems.Add("项目负责人" + i.ToString());
lvitem.SubItems.Add("项目年度-" + i.ToString());
lvitem.SubItems.Add(DateTime.Now.ToString() + " -" + i.ToString());
lvitem.SubItems.Add(" #" + i.ToString());
lv.Items.Add(lvitem);
}

}
private void RefreshDispCH(int ch)
{

for (int i = 0; i < 7; i++)
{

}

}

public delegate void D_RefreshDisp();
public delegate void D_RefreshDispCH(int ch);

} while (isStart);

}

private void Startbutton_Click(object sender, EventArgs e)
{
