DataTable to Dynamic List

format strings

Last day I got a requirement, it need a pivot table. I generated this table in SQL and read it to a datatable. No issues. Then I want convert this datatable to a list. I can’t create a entity because columns are dynamic. I stuck here some time and got a solution .

 

 

public static class HelperExtensions
{
  public static List<dynamic> ToDynamic(this DataTable dt)
  {
    var dynamicDt = new List<dynamic>();
    foreach (DataRow row in dt.Rows)
    {
      dynamic dyn = new ExpandoObject();
      dynamicDt.Add(dyn);
      foreach (DataColumn column in dt.Columns)
      {
         var dic = (IDictionary<string, object>)dyn;
         dic[column.ColumnName] = row[column];
      }
    }
    return dynamicDt;
  }
}
