rdlc报表疑云，请赐教！！！

        //取得数据集

        string connstring = "Data Source=127.0.0.1;Initial Catalog=abn_LTGS;User ID=sa;Password=;Persist Security Info=True;MultipleActiveResultSets=False;Packet Size=4096";

        System.Data.SqlClient.SqlConnection conn1 = new System.Data.SqlClient.SqlConnection(connstring);

        System.Data.SqlClient.SqlCommand command1 = new System.Data.SqlClient.SqlCommand("select lane from deviantList", conn1);

        System.Data.SqlClient.SqlDataAdapter ada1 = new System.Data.SqlClient.SqlDataAdapter(command1);

        DataSet c_ds = new DataSet();

        try
        {

            conn1.Open();

            ada1.Fill(c_ds);

        }

        finally
        {

            conn1.Close();

            command1.Dispose();

            conn1.Dispose();

        }
        //为报表浏览器指定报表文件
        this.reportViewer1.LocalReport.ReportPath = @"d:\documents\visual studio 2010\Projects\报表1\报表1\Report1.rdlc";
       this.reportViewer1.LocalReport.DataSources.Clear();
        this.reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("DataSet1", c_ds.Tables[0]));
      this.reportViewer1.RefreshReport();
