报表 Report1.rdlc 是在另外一个项目里设计的，把它复制到本项目里，可以预览表格，但是点击页面设置按钮就出现“System.ExecutionEngineException”异常错误，请各位帮忙看看是怎么回事？


以下是代码：

private void button3_Click(object sender, EventArgs e)
        {

            //获取数据表
                     
            OleDbConnection db = getConn(); //getConn():得到连接对象

            db.Open();

            string sql = "select * from RKDATABASE order by 编号 desc"; //选中所有，降序排列，最新的记录在上面


            OleDbDataAdapter da = new OleDbDataAdapter(sql, db); //创建适配对象

            dt = new DataTable(); //新建表对象

            da.Fill(dt);          //用适配对象填充表对象


            db.Close();

            //实例化一个ReportViewer
            Microsoft.Reporting.WinForms.ReportViewer  ReportViewer1 = new Microsoft.Reporting.WinForms.ReportViewer();
          
          
            Form fm = new Form();     
            fm.Width = 700;
            fm.Height = 650;

            fm.StartPosition = FormStartPosition.CenterScreen;   //居中显示

            fm.Text = "打印预览";

            fm.Controls.Add( ReportViewer1);  //放在窗口里面
           
            try
            {
                //获取报表文件并付给reportViewer控件
                 ReportViewer1.LocalReport.ReportPath = System.Environment.CurrentDirectory + "\\Report1.rdlc";

               
                 ReportViewer1.Width = this.Width ;
                 ReportViewer1.Height = this.Height;

                  ReportViewer1.Parent = fm;
               
              
                //指定数据集

                 ReportViewer1.LocalReport.DataSources.Clear();
             
                ReportDataSource rpt = new ReportDataSource("myds", dt);

                 ReportViewer1.LocalReport.DataSources.Add(rpt);
              
                 ReportViewer1.ZoomMode = ZoomMode.Percent;


                //显示报表
                 ReportViewer1.Show();
                 ReportViewer1.RefreshReport();
                 ReportViewer1.BringToFront();   //最前端显示

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
                return;
            }

            fm.ShowDialog();


        }
