C#BackgroundWorker、DataSet和DataGridView多线程更新

请提前注意，这是我第一次使用多线程，也是我第一次尝试使用第二个线程填充/编辑

数据集

，然后将该

数据集

显示到专用于

DataGridView

控件的Windows窗体中。我读过关于线程安全代码的各种文章，我相信我的理解是正确的

在调试期间，

数据集

被传递到

BackgroundWorker

，并使用

e.Result

从线程中拉出。然后它被分配回整个程序中使用的变量

当查看

数据集

对象的内存时，当它到达

frmGridView

时，它拥有加载到该对象中的所有数据，但控件从未更新

以下是我的代码片段。任何关于更好的代码组织/结构的建议、建议和想法都会非常有用。同样，这是我第一次使用

BackgroundWorker

谢谢

方法片段：

   private DataSet ProcessListXml(DataSet _dsData, BackgroundWorker _bwThread)

   ..

   _dsData.Tables["MainList"].BeginLoadData();

   ..

   DataRow row = _dsData.Tables["MainList"].NewRow();

   ..

   _dsData.Tables["MainList"].Rows.Add(row);

   .. 
       _bwThread.ReportProgress((currLine / totalLines) * 100); 
   } //reader.Read()

   ..

   _dsData.Tables["MainList"].EndLoadData();
   _dsData.Tables["MainList"].AcceptChanges();
   return _dsData;

public partial class frmDataView : Form
{

    DataSet dsGameList;

    public frmDataView(DataSet _in)
    {
        dsGameList = _in;
        InitializeComponent();
        dataGridView.DataSource = dsGameList.Tables["GameList"];
    }

    public void RefreshView()
    {
        dataGridView.Refresh();
    }

private void bwThread_DoWork(object sender, DoWorkEventArgs e)
{
    BackgroundWorker worker = sender as BackgroundWorker;
    e.Result = ProcessMameListXml(dsData, worker);
}

private void bwThread_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    dvProgressBar.UpdateProgressBar(e.ProgressPercentage);
}

private void bwThread_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    dsData = (DataSet)e.Result;
    dvProgressBar.Close();
    UpdateUIElements();
    dvWindow.RefreshView();
}

DataGridView窗口窗体：

   private DataSet ProcessListXml(DataSet _dsData, BackgroundWorker _bwThread)

   ..

   _dsData.Tables["MainList"].BeginLoadData();

   ..

   DataRow row = _dsData.Tables["MainList"].NewRow();

   ..

   _dsData.Tables["MainList"].Rows.Add(row);

   .. 
       _bwThread.ReportProgress((currLine / totalLines) * 100); 
   } //reader.Read()

   ..

   _dsData.Tables["MainList"].EndLoadData();
   _dsData.Tables["MainList"].AcceptChanges();
   return _dsData;

public partial class frmDataView : Form
{

    DataSet dsGameList;

    public frmDataView(DataSet _in)
    {
        dsGameList = _in;
        InitializeComponent();
        dataGridView.DataSource = dsGameList.Tables["GameList"];
    }

    public void RefreshView()
    {
        dataGridView.Refresh();
    }

private void bwThread_DoWork(object sender, DoWorkEventArgs e)
{
    BackgroundWorker worker = sender as BackgroundWorker;
    e.Result = ProcessMameListXml(dsData, worker);
}

private void bwThread_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    dvProgressBar.UpdateProgressBar(e.ProgressPercentage);
}

private void bwThread_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    dsData = (DataSet)e.Result;
    dvProgressBar.Close();
    UpdateUIElements();
    dvWindow.RefreshView();
}

BackgroundWorker代码片段：

   private DataSet ProcessListXml(DataSet _dsData, BackgroundWorker _bwThread)

   ..

   _dsData.Tables["MainList"].BeginLoadData();

   ..

   DataRow row = _dsData.Tables["MainList"].NewRow();

   ..

   _dsData.Tables["MainList"].Rows.Add(row);

   .. 
       _bwThread.ReportProgress((currLine / totalLines) * 100); 
   } //reader.Read()

   ..

   _dsData.Tables["MainList"].EndLoadData();
   _dsData.Tables["MainList"].AcceptChanges();
   return _dsData;
