我的代码有什么问题？我无法在浏览器中查看它。我搜索了google，但是没有找到答案。已经两天了，我正在寻找解决方案。有人能帮忙吗？谢谢。

public partial class WebForm1 : System.Web.UI.Page
{
    string connectionString = "server=" + 
           ConfigurationManager.AppSettings["Server"] + ";uid=" + 
           ConfigurationManager.AppSettings["User ID"] + ";pwd=" + 
           ConfigurationManager.AppSettings["Password"] + ";database=" + 
           ConfigurationManager.AppSettings["Database Name"] + 
           ";Command Timeout=28800;";    

    protected void Page_Load(object sender, EventArgs e)
    {
        EmpReport crystalReport = new EmpReport();
        dsEmp ds = GetData();
        crystalReport.SetDataSource(ds);
        this.CrystalReportViewer1.ReportSource = crystalReport;
        this.CrystalReportViewer1.RefreshReport();
    }

    private dsEmp GetData()
    {
        string query = "SELECT * FROM emp_table";
        MySqlConnection con = new MySqlConnection(connectionString);
        MySqlCommand cmd = new MySqlCommand(query);
        MySqlDataAdapter da = new MySqlDataAdapter();
        cmd.Connection = con;
        da.SelectCommand = cmd;
        dsEmp ds = new dsEmp();
        da.Fill(ds, "DataTable1");
        return ds;
    }
}
