c# - how do I make my DataGridView equal to my List<List<decimal>>? -

i have list of decimal lists, when filled it's grid...

2.0, 3.1, 4.0 3.2, 7.0, 1.4 6.0, 3.1, 8.8 

the code list...

list<list<decimal>> rows = new list<list<decimal>>(); 

is there easy way make me datagridview display data, tried...

datagridview1.datasource = rows; 

but did not work.

the grid outputs this...

one way convert list of lists datatable object , set datasource property. here example of method such conversion:

public datatable createdatatable(list<list<decimal>> data) {     datatable table = new datatable();      if (data.count == 0)         return table;      int fields = data[0].count;      (int = 0; < fields; i++)     {         table.columns.add("column" + (i + 1), typeof (decimal));     }      foreach (var list in data)     {         var row = table.newrow();          (int = 0; < fields; i++)         {             row.setfield(i, list[i]);         }          table.rows.add(row);     }      return table; } 

and can set datasource property this:

datagridview1.datasource = createdatatable(rows);
