c# - Lambda with nested classes -

-

i have posted question while ago got partial answer issue, thought post more explanation hoping more accurate answer. have 2 classes:

public class employee {     public string name { get; set; }     public list<cars> cars { get; set; } }  public class car {     public int carid { get; set; }     public cartypes cartype { get; set; }     public enum cartypes     {         van,         smallcar     } }

i'm trying employees have vans allocated ignoring smallcars using lambda, tried line:

list<employee> employeeswithvans = allemployees.where(emps => emps.car.any(cartype => cartype.cartype == car.cartypes.van)).tolist();

but gets employees if @ least 1 van allocated employee (.any) if try (.all) bring nothing not employees has van.

any idea if can achieved using nested lambda?

thanks.

edit:

employee mark = new employee(); mark.cars.add(new car() { cartype = car.cartypes.van, carid = 12 }); mark.cars.add(new car() { cartype = car.cartypes.van, carid = 13 }); mark.cars.add(new car() { cartype = car.cartypes.smallcar, carid = 14 });  employee lisa = new employee(); lisa.cars.add(new car() { cartype = car.cartypes.van, carid = 15 }); lisa.cars.add(new car() { cartype = car.cartypes.smallcar, carid = 16 }); lisa.cars.add(new car() { cartype = car.cartypes.smallcar, carid = 17 });      list<employee> employeeswithvans should contain:      employee filteredmark contains:     mark.cars.add(new car() { cartype = car.cartypes.van, carid = 12 });     mark.cars.add(new car() { cartype = car.cartypes.van, carid = 13 });      employee filteredlisa contains:     mark.cars.add(new car() { cartype = car.cartypes.van, carid = 15 });

try instead:

list<employee> temp = allemployees.where(emps => emps.cars.any(cartype => cartype.cartype == cars.cartypes.van)).tolist();  list<employee> employeeswithvans = (from item in temp            select new employee{                                       name = item.name,                                       cars = (item.cars.where( car => car.cartype == cars.cartypes.van)).tolist()                                }).tolist();

this tried (in linqpad):

void main() {     list<employee> allemployees = new list<employee>();      list<cars> lcars1 = new list<cars>();     cars car1 = new cars();     car1.cartype = cars.cartypes.van;     lcars1.add(car1);lcars1.add(car1);      cars car2 = new cars();     car2.cartype = cars.cartypes.smallcar;     lcars1.add(car2);      list<cars> lcars2 = new list<cars>();     lcars2.add(car1);lcars2.add(car2);lcars2.add(car2);      allemployees.add(new employee(){ name="emp1", cars = lcars1});     allemployees.add(new employee(){ name="emp2", cars = lcars2});     allemployees.add(new employee(){ name="emp3", cars = lcars1 });     allemployees.add(new employee(){ name="emp4", cars = lcars2});      list<employee> temp = allemployees.where(emps => emps.cars.any(cartype => cartype.cartype == cars.cartypes.van)).tolist();      list<employee> employeeswithvans = (from item in temp             select new employee{                                          name = item.name,                                          cars = (item.cars.where( car => car.cartype == cars.cartypes.van)).tolist()                                 }).tolist();      employeeswithvans.dump(); }

output:

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
