Convert DataTable to List<T> where Class of List is Dynamic

I am executing a stored procedure from C# code

private void DataToGrid()
{
    DataTable dt = new DataTable();
    string[,] aryPara = new string[,] 
    {{ "@pClassId", "10" } ,
    { "@pMediumId", "11" } ,
    { "@pStreamId", "12" } ,
    { "@pSessionId","13" } ,
    { "@pSectionId", "15" } ,
    { "@pShiftId", "16" } ,
    { "@pDateId", "17" } };

    dt = CallStoredProcedureUsingAdapterFillDataTabel("ssspAtdDailyattendance", aryPara);  
    DatagridView1.DataSource = dt;
}

public DataTable CallStoredProcedureUsingAdapterFillDataTabel(string StoredProcedureName, [Optional] string[,] aryParameters)
{
    SqlConnection con = new SqlConnection();
    con.ConnectionString = "Data Source=AIS-OCTACORE\SQLserver2008r2;Initial Catalog= SchoolSoulDataTest; integrated security=SSPI";
    con.open();
    SqlCommand lSQLCmd = new SqlCommand();
    SqlDataAdapter adp = new SqlDataAdapter();
    DataTable dt = new DataTable();
    lSQLCmd.CommandType = CommandType.StoredProcedure;
    lSQLCmd.CommandText = StoredProcedureName;
    lSQLCmd.CommandTimeout = 300;
    try
    {
        for (int i = 0; i < aryParameters.GetLength(0); i++)
        {
            lSQLCmd.Parameters.Add(new SqlParameter(aryParameters[i, 0], aryParameters[i, 1]));
        }
    }
    catch (Exception ex)
    {

    }
    lSQLCmd.Connection = con;
    adp.SelectCommand = lSQLCmd;
    adp.Fill(dt);
    clsConnectionClose();
    return dt;
}

Where ssspAtdDailyattendance is a Dynamic Stored Procedure in which data returned by the stored procedure has variable number of columns.

Now I want to convert DataTable dt to a List<T> but as dt return variable number of columns thus type of T is not Fixed

So my question is how could I convert dt to List?
