如何从后台线程正确更新数据绑定datagridview

public delegate void UpdateDataGridViewDelegate(DataTable dataTable);

public void UpdateDataGridView(DataTable dataTable)
{
    if (this.dataGridView1.InvokeRequired)
    {
        UpdateDataGridViewDelegate updateDataGridViewDelegate = new UpdateDataGridViewDelegate(UpdateDataGridView);
        this.Invoke(updateDataGridViewDelegate, dataTable);
    }
    else
    {
        this.dataGridView1.DataSource = dataTable;
    }
}

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    // 获取数据
    DataTable dataTable = GetData();

    // 更新datagridview
    UpdateDataGridViewDelegate updateDataGridViewDelegate = new UpdateDataGridViewDelegate(UpdateDataGridView);
    this.Invoke(updateDataGridViewDelegate, dataTable);
}

private void Form1_Load(object sender, EventArgs e)
{
    BindingSource bindingSource = new BindingSource();
    bindingSource.DataSource = typeof(DataTable);
    this.dataGridView1.DataSource = bindingSource;
}

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    // 获取数据
    DataTable dataTable = GetData();

    // 更新BindingSource对象的DataSource属性
    this.bindingSource1.DataSource = dataTable;
}
