Saving classes (not objects) in an array

Questions & Answers

bool InContext(Class array, Item item)
{
for(int i = 0;i<array.length;i++)
{
if(item is array*)*
{
return true;
}
}
return false;
}
Is there anyway to store a bunch of classes so that I can tell if one of my items is inheriting from it?
I want this function for checking if an item is within context (for context sensitive menus) to be fairly dynamic; so writing it in manually isn’t really an option.

Assuming that you have items hierarchy like this

class Item
{
}

class ItemChild1 : Item
{
};

class ItemChild2 : Item
{
};

class ItemChild3 : Item
{
}

you can use the next code to check if an item is of one of the expected types:

//  Array of expected classes 
Type[] classes = { typeof(ItemChild1), typeof(ItemChild2), typeof(ItemChild3) };

...

//  Check the type matching
bool InContext(Type[] array, Item item)
{
    if ( item == null )
        return false;

    for (int i = 0; i < array.Length; i++)
    {
        if (item.GetType() == array*)*

{
return true;
}
}
return false;
}
// LINQ version
public static bool InContextLINQ(Type[] array, Item item)
{
return ( item != null ) && array.Any(t => item.GetType() == t);
}
Types array elements should not be necessarily inherited from the hypothetical Item parent class - just use some common type to pass the item object to the function (System.Object should be enough).
