用ReportViewer动态加载rdlc文件时出了只读错误,请问是怎么回事?

[妈妈baby坊]

string sqlcon = @"server=.\ALONG;database=RdlcTest;uid=sa;";
        string sql = "select * from Table_Test";
        System.Data.DataSet ds = new System.Data.DataSet();
        using (System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(sqlcon))
        {
            con.Open();
            System.Data.SqlClient.SqlDataAdapter da = new System.Data.SqlClient.SqlDataAdapter(sql, con);
           ;
            da.Fill(ds);

        }
        this.rpvConsumptionGraph.LocalReport.ReportPath = Server.MapPath("RdlcPieCharts.rdlc");//这个位置报的只读错误,请各位帮帮忙,看一下,谢谢
    
        this.rpvConsumptionGraph.LocalReport.DataSources.Clear();
        
        ReportDataSource rd = new ReportDataSource("DataSet1", ds.Tables[0]);
        this.rpvConsumptionGraph.LocalReport.DataSources.Add(rd);
        this.rpvConsumptionGraph.LocalReport.Refresh();

private void frmPrint_Load(object sender, EventArgs e)
        {
            //显示报表内容
            //int MemberId = Program.Num_id;
            int MemberId = 1;
            da = new MySqlDataAdapter("select a.MemberId as MemberId,MemberName,Score,Type from member as a left join memscore as b on a.memberid = b.memberid where a.memberid =" + MemberId + "", conn);
            da.Fill(Mydata, "MyReportDataTable");

            crystalReport11.Load(Application.StartupPath + "CrystalReport1.rpt");
            crystalReport11.SetDataSource(Mydata);
             crystalReportViewer1.ReportSource = crystalReport11;
            crystalReportViewer1.ShowPrintButton = false;

        }
