Access DataSet From Seperate Class

I have a dataset that is being filled in one class and I want to access the data from a separate class.  How would I do such?

For example, let's take this snippet below that should better explain what I need to accomplish:

namespace Connection
{
  class ServerConnect
  {
    public static string FillDataSet()
    {
      SqlConnection conn;
      string sql = null;
      string data = null;
      string ConnectionString = "Here is the conection";
      conn = new SqlConnection(ConnectionString);
      conn.Open();
      sql = "Here is SQL Statement";
      SqlDataAdapter dscmd = new SqlDataAdapter(sql, conn);
      DataSet ds = new DataSet();
      dscmd.Fill(ds);
    }
  }
}
//Now from this class I want to access the dataset here --
//Will the same method for writing the data work even though it is in a different class?
namespace WriteData
{
  class WriteItOut()
  {
    for (i = 0; i<= ds.Tables[0].Rows.Count - 1; i++)
    {
      for (j = 0; j<= ds.Tables[0].Columns.Count - 1; j++)
      {
        data = ds.Tables[0].Rows[i].ItemArray[j].ToString();
        //Writing here
      }
    }
  }
}
