C # Tips for solving LINQ-to-be () failures

Objective

I used LINQ GroupBy and by-numbers in a data list a few days ago. Sorting in the normal use of the machine, sent to the test after the sort of death, is depressed, always thought to be a procedural problem. So I consulted another colleague. The answer is as follows.

CultureInfo Culture = Cultureinfo.getcultureinfo ("ZH-CN"); List<TeamDto> Teamdtos =teams. GroupBy (x=New{x.testid, x.testname}) . Select (g=Newteamdto () {TestID=G.key.testid, Test=G.key.testname, Teams=g.tolist ()}) . (T=>t.test,stringcomparer.create (Culture,true))                    . ToList ();
