Answer 1

I think you looking something like this. Hope it's working for you.

From dynamic list to DataTable:

   List<dynamic> dlist=new List<dynamic> 
   var json = JsonConvert.SerializeObject(dlist);
   DataTable dataTable = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));

Also to get JsonString from DataTable:

string JSONresult = JsonConvert.SerializeObject(dataTable);

The following is the method through which you can convert any list object to datatable..

 public DataTable ConvertToDataTable<T>(IList<T> data)
    {
        PropertyDescriptorCollection properties =
           TypeDescriptor.GetProperties(typeof(T));
        DataTable table = new DataTable();
        foreach (PropertyDescriptor prop in properties)
            table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);
        foreach (T item in data)
        {
            DataRow row = table.NewRow();
            foreach (PropertyDescriptor prop in properties)
                row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
            table.Rows.Add(row);
        }
        return table;

    }

Answer 3

 public DataTable ToDataTable<T>(dynamic items)
    {

        DataTable dtDataTable = new DataTable();
        if (items.Count == 0) return dtDataTable;

        ((IEnumerable)items[0]).Cast<dynamic>().Select(p => p.Name).ToList().ForEach(col => { dtDataTable.Columns.Add(col); });

        ((IEnumerable)items).Cast<dynamic>().ToList().
            ForEach(data =>
            {
                DataRow dr = dtDataTable.NewRow();
                ((IEnumerable)data).Cast<dynamic>().ToList().ForEach(Col => { dr[Col.Name] = Col.Value; });
                dtDataTable.Rows.Add(dr);
            });
        return dtDataTable;
    }
