c# - C#中的进度条和backgroundworker

Question

目前，我正在从事一个项目，该项目需要使用Web服务中的大量数据，
服务类将输入日期发送到服务器并获取结果，
由于该过程很耗时，因此需要用户结合进度条和后台工作人员才能向用户显示该过程的百分比。我已经浏览了很多有关此主题的示例代码，但是仍然找不到最佳的方法。请你帮忙，
我的代码如下，

private  MyCollection[] callWebService(string[] Inputs, string method)
{
    List<string> results = new List<string>();
    string fiel dNames = ""; // todo - fix this if nothing left in loop
    int sizeOfArray = 500;
    for (int i = 0; i < Inputs.Length; i = i + sizeOfArray)
    {
        string[] outputRecords;
        int errorCode;
        string errorString;
        string[] thisFiveHundred = createSubArray(Inputs, i, sizeOfArray);


        iq.NameValuePair[] namevaluepairs = new iq.NameValuePair[0];
        fieldNames = iqOfficeWebservice.BatchStan(method, thisFiveHundred, null, "",        out outputRecords, out errorCode, out  errorString);
        results.AddRange(outputRecords);
    }
    results.ToArray();
    IAddress[] formattedResults = convertStringsToInputs(fieldNames, results);
    return formattedResults;
}

    private void cmdButton_Click(object sender, EventArgs e)
    {
        BackgroundWorker worker = new BackgroundWorker();
        worker.WorkerReportsProgress = true;
        worker.DoWork += new DoWorkEventHandler(worker_DoWork);
        worker.ProgressChanged += new ProgressChangedEventHandler(worker_ProgressChanged);
        worker.RunWorkerAsync();
    }

    private void worker_DoWork(object sender, DoWorkEventArgs e)
    {
        BackgroundWorker worker = sender as BackgroundWorker;

        for (int i = 0; i < 101; i++)
        {
            worker.ReportProgress(i);
            System.Threading.Thread.Sleep(1000);
        }
    }

    private void worker_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        lblProgress.Text = ("Progress: " + e.ProgressPercentage.ToString() + "%");
    }
