帮我.谢谢.
代码如下.

Hi all, I have a crystal report that displays data from a dataset. When i run the program it does not display any data but the dataset has a number of records. It shows an error ''value does not fall within the expected range''. I do not use any parameters in crystal report.
Help me. Thanks.
The code is follows.

private void Form1_Load(object sender, EventArgs e)
        {
            DataSet ds = new DataSet();
            ds.Tables.Add("Doctors");
            Get_Doctors();
            CrystalReport1 rpt = new CrystalReport1();
            rpt.SetDataSource(ds);
            crystalReportViewer1.ReportSource = rpt;
        }
        private void Get_Doctors()
        {
            da = new SqlDataAdapter("SELECT D_Name,D_Address_L1 from doctors", Dbcon);
            da.Fill(ds, "Doctors");
        }

推荐答案

rpt.SetDataSource(ds.Tables[0]);
OR
rpt.SetDataSource(ds.Tables["Doctors"]);
