（一）使用規則

public IAsyncResult BeginInvoke(Delegate method);
public IAsyncResult BeginInvoke(Delegate method, params object[] args);

①：傳遞一個委托

this.BeginInvoke(new InvokeMethod(InvokeXXX), new object[] { listDgv });

public delegate void InvokeMethod(object x);
public void InvokeXXX(object x)
{
dgvMain.DataSource = x;
}

②：傳遞系統委托 public delegate void Action<T>(T obj)

this.BeginInvoke(new Action

③：傳遞匿名委托

算法定義IAsyncResult asyncResult = this.BeginInvoke(new Action<object>(t => {
    //object temp = t;
    dgvMain.DataSource = t;
    int x = 0;
    MessageBox.Show("導入成功
 
");
}), new object[] { listDgv });

Invoke，BeginInvoke，EndInvoke
