如何在将XML文件导入SQLServerManagementStudio时为存储过程创建进度条

我被卡住了：这是我的示例代码

namespace WindowsFormsApplicationXml
{
    public partial class Form1 : Form
    {
        string ConString, CmdString;
        int TotalRecords;
        SqlConnection con;
        SqlCommand cmd;
        SqlDataReader reader;
        public Form1()
        {
            InitializeComponent();
            ConString = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
        }
        public class MyWorkerClass
        {
                    public int UserID;
        }
        private void btnSaveXML_Click(object sender, EventArgs e)
        {
            MyWorkerClass obj = new MyWorkerClass();
            if (!backgroundWorker1.IsBusy)
            {
                TotalRecords = GetTotalRecords();
                progressBar1.Maximum = TotalRecords;
                backgroundWorker1.RunWorkerAsync(obj);
            }
        }
        private int GetTotalRecords()
        {
            try
            {

                    cmd = new SqlCommand("SELECT COUNT(UserID) FROM UserMaster", con);
                    con.Open();
                    TotalRecords = int.Parse(cmd.ExecuteScalar().ToString());
                    con.Close();
                }
