How to remove a item based on single property value

Question

I have a List* <plantcollection> _PlantCollection list which contains 5 properties.

C#

class PlantCollection
    {
        private readonly Parser cParser = new Parser();
        public string Name { get; set; }
        public string SafeToFeed { get; set; }
        public string URLOfPlant { get; set; }
        public BitmapImage PlantThumbnail { get; set;}
        public string PlantTrafficColour { get; set; }
}

How would I remove a item from the list based on a condition of a single value?

E.g

If Safe To Feed contains ("Do Not Feed").. remove item. I tried using an the index of the item but it just return as -1.

I tried this but returns an exception - "collection has been modified"

C#

int i = 0;
foreach (PlantCollection plant in cParser._PlantCollection)
{
    if (cParser._PlantCollection[i].SafeToFeed.Contains("green"))
    {
        cParser._PlantCollection.Remove(plant);
        i++;
    }


}

Solution 1

I would do something similar to this

C#

//Find all items that contain "Do Not Feed"
List<plantcollection> DataToRemove = Container.PlantCollection.FindAll(p=> p.SafeToFeed.Contains("Do Not Feed") == true);

if(DataToRemove != null)
{
  foreach(PlantCollection item in DataToRemove)
  {
    Container.PlantCollection.Remove(item);
  }
}

Thank you for the reply. I tried this but VS2010 did not recongize the Container.PlantCollection?

Simon_Whale 12-Aug-13 6:39am

you would replace Container.PLantCollection for cParser._PlantCollection

Oh! Sorry, Thank you!

Ignore this. I made a copy of the list so that it would not directly affect it.

Thank you anyway!

You could do something similar but you would have to loop through the items collection to view each data record
