asp.net - find most occurrences in linq to sql c# -

i have below query gets name , totalpoints follows:

var gradedata = (from data in oangiectxt.prc_shopinstancecustomersdata(convert.toint32(this.shopinstanceid), 10000, false)                          .where(row => row.recievedpoints != "n/a")                         .groupby(row => new { row.name })                         .select(g => new                         {                             totalpoints = g.sum(x => convert.todouble(x.recievedpoints) * (x.weightage.tostring() == "0.00" ? 1 : convert.todouble(x.weightage))),                             name = g.key.name                         })                          select data).tolist(); 

i have data below:

totalpoints        name   5                    10                 b   5                  c   15                 d   5                  e 

if observe above list 5 common.

i have fetch value "gradedata".

can me how that?

thanks in advance...

-- both solutions below working vote both.. thanku

var mostcommon = gradedata.groupby(x => x.totalpoints)     .orderbydescending(g => g.count())     .select(g => g.key)     .first();
