我的代码似乎有什么问题?我无法在浏览器中查看它。我搜索了谷歌,但找不到答案。已经2天了,我正在寻找解决方案。谁能帮忙谢谢。

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;
    }
}

通过将C:// inetpub / wwwroot / aspnet_client / system_web中找到的4_0_30319文件夹放入项目的根文件夹中,我可以显示Crystal报表。还要确保在项目文件(Web.config)中配置正确。
