Hi,

I am working on a code

C#

int a = 0, b = 1, c = 2, d = 3;

                    if (select1 == "Red")
                        busOneDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[a]);
                    if (select1 == "Yellow")
                        busOneDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[b]);
                    if (select1 == "Green")
                        busOneDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[c]);
                    if (select1 == "Orange")
                        busOneDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[d]);



                    if (select2 == "Red")
                        busTwoDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[a]);
                    if (select2 == "Yellow")
                        busTwoDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[b]);
                    if (select2 == "Green")
                        busTwoDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[c]);
                    if (select2 == "Orange")
                        busTwoDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[d]);

User may select any of the 4 colors red,yellow,green,orange

I need to write a code in a way, if user selcts red and yellow then I need to take remaining two colors and work out on them.

suppose if the user selects Red and Yellow then I need to take
SCANLA.Run.BusDetails[c],SCANLA.Run.BusDetails[d] and work on them

How can I write code to disregard the user selected colors???

Thanks
John

C#

string[] userInput = {"red", "orange"};
string[] colors = {"red", "yellow", "green", "orange"};
for (int i = 0; i < colors.Length; i++)
{
  if (userInput.Contains(colors[i]) == false)
  {
   var busDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[i]);
   // post processing of bus details here (for example, adding busDetails to list of details
  }
}

Solution 2

C#

for (int i = 0; i < 3; i++)
{
  if (msgDetailsOfBus(SCANLA.Run.BusDetails[i] != busOneDetails  & msgDetailsOfBus(SCANLA.Run.BusDetails[i] != busTwoDetails)
  {
   BusDetails busDetails = msgDetailsOfBus(SCANLA.Run.BusDetails[i]);
   .
   .
   .
  }
}

Here's an illustration of the general principle of returning a List of objects not in some other List, using Linq. You'll have to adapt it to your work:

C#

List<Color> clrList = new List<Color>{Color.Red, Color.Yellow, Color.Green, Color.Orange};

private List<Color> selectOtherColors(List<Color> selectedColors)
{
   if(selectedColors.Count != 2) throw new ArgumentException("Must supply two Colors !");

   return clrList.Where((clr, ndx) => ! selectedColors.Contains(colorList[ndx])).ToList();
}

Test:

C#

var useTheseColors = selectOtherColors(new List<Color>{Color.Red, Color.Yellow});

This will return a List<Green,Orange>
