c# - Splitting a list of objects into multiple separate lists based on a given criteria -

consider following list:

var headers = new list<tableheader>() {     new tableheader("column1", 3),     new tableheader("column2", 2),     new tableheader("column3", 1, alignment.right),     new tableheader("column4", 1),     new tableheader("column5", 1),     new tableheader("column6", 6, alignment.right),     new tableheader("column7", 2, alignment.right), }; 

where second parameter in tableheader constructor width.

i'd split above list n separate lists each of containing total maximum number of w width. example, if w equals 7, need 3 lists containing tableheader objects, follows:

1. column1, column2, column3, column4 (since 3+2+1+1 <= 7).
2. column5, column6
3. column7

any highly appreciated.

this i've implemented. better idea?

public static ienumerable<ienumerable<t>> split<t>(this ienumerable<t> source, double maxwidth) t : tableheader {     while (source.any())     {         int skip = 0;          double totalwidth = 0;         yield return source.takewhile(h =>         {             totalwidth += h.width;             if (totalwidth <= maxwidth)                 skip++;              return totalwidth <= maxwidth;         });          source = source.skip(skip);     } }
