using System;
using System.Data;

class Program
{
    static void Main()
    {
      // Create two DataTable instances.
      DataTable table1 = new DataTable("patients");
      table1.Columns.Add("name");
      table1.Columns.Add("id");
      table1.Rows.Add("sam", 1);
      table1.Rows.Add("mark", 2);

      DataTable table2 = new DataTable("medications");
      table2.Columns.Add("id");
      table2.Columns.Add("medication");
      table2.Rows.Add(1, "atenolol");
      table2.Rows.Add(2, "amoxicillin");

      // Create a DataSet and put both tables in it.
      DataSet set = new DataSet("office");
      set.Tables.Add(table1);
      set.Tables.Add(table2);

      // Visualize DataSet.
      Console.WriteLine(set.GetXml());
    }
}

if you want to store data whatever added in data table(s) use this code

//it will write xml file
set.WriteXml("filename.xml");

//it will read xml file
ds.ReadXml("filename.xml");

rebind the dataset once you read xml file, so you can load saved data.

I think all the above information is good.  I want to make sure my original question was clear though.  In my project I have added a new item and selected "dataset" and named it DataSet_SysInfo.xsd.  In the dataset design view I created a "DataTable" and named it AssetInfo and added columns to it.  I have then designed my report.rdlc to point to that datatable.  So on my report form, in the report viewer I pointed it to report.rdlc. So how to I add information to the datatable I have alread created in design view?
