How to return a DataSet to a View

Question

I am sending a standard Sql select statement to my Sql box via the SqlDataAdapter, then populating a DataSet object.

I can access the rows in the resulting DataSet,

If you're stuck with using DAO, I would suggest not using a DataSet and instead use a strongly typed class with the speed of SqlDataReader.GetValues() method. It's more work, but it has to be done somewhere if you want strongly typed classes which I would highly recommend.

public class Person
{
  public Person(Object[] values]
  {
    this.FirstName = (string)values[0];
    this.LastName = (string)values[1];
    this.Birthday = (DateTime)values[2];
    this.HasFavoriteColor = (bool)values[3];
  }

  public string FirstName { get; private set; }
  public string LastName { get; private set; }
  public DateTime Birthday { get; private set; }
  public bool HasFavoriteColor { get; private set; }
}

public static void DbRegressionExec()
{
    List viewModel = new List();

    // SELECT TABLE CONTENTS FROM SQL !!
    RegressDB_TableList regresDB = new RegressDB_TableList();
    string sqlStr = "select
        FirstName
        ,LastName
        ,Birthday
        ,HasFavoriteColor
      from [RegressionResults].[dbo].[Diff_MasterList] 
      order by TableName";

    // POPULATE VIEWMODEL OBJECT
    sqlConn.Open();

    try
    {
      using (SqlCommand com = new SqlCommand(sqlStr, sqlConn))
      {
        using (SqlDbReader reader = com.ExecuteReader())
        {
          while(reader.Read())
          {
            viewModel.Add(new Person(com.GetValues()));
          }
        }
      }
    }
    catch (Exception e)
    {
        throw;
    }
    finally
    {
        sqlConn.Close();
    }

    return this.View(viewModel);
}
