求一sql的linq语句

SQL code

SELECT (SELECT COUNT(*) FROM TableName WHERE CODE=a.CODE)AS [COUNT],*FROM TableName as aWHERE [ID] = '30BCA6A3-0B18-4224-9248-14E2CD3F20B6'

C# code

var query=from a in db.TableName          where a.ID=="30BCA6A3-0B18-4224-9248-14E2CD3F20B6"          select new         {             Count=db.TableName.Where(b=>b.CODE==a.CODE).Count(),            a        };
