Hi,

C#

 class SampleData
    {
        public string Id { get; set; }
        public string Name { get; set; }
        public List<string> Tests { get; set; }

    }

private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            DataTable dt = new DataTable();
            //Fill DataTable
            List<sampledata> data = new List<sampledata>();
            foreach (DataRow dr in dt.Rows)
            {
                if (data.Where(sd => sd.Id == dr["Id"].ToString()).ToList().Count == 0)
                {
                    SampleData sampleData = new SampleData();
                    sampleData.Id = dr["Id"].ToString();
                    sampleData.Name = dr["Name"].ToString();
                    sampleData.Tests = new List<string>();
                    sampleData.Tests.Add(dr["Test"].ToString());
                    
                }
                else
                {
                    SampleData s = data.Single(sd => sd.Id == dr["Id"].ToString());
                    s.Tests.Add(dr["Test"].ToString());
                }
            }
        }
</string></sampledata></sampledata></string>
