public virtual ICollection PurchasedItems { get; set; } How to properly assign my getPur() method to Transaction.PurchasedItems I need a resultset which is a combination of Transaction and PurchasedItems. I'm looking for the result same like in image. I tried implementing ICollection interface. I wanted to implement a CopyTo method, it fills the array with some objects, but after stepping out of the method the array is still empty (just like if there's a ref keyword missing, but I've never seen implementation of this method with a ref keyword, so I suppose it shouldn't be necessary to use it here?). ICollection: Copy the contents to an array to iterate it 11.26.6. Collections interoperability: cast Array to IList, IList to ICollection, ICollection to IEnumerable, non-generic to generic
If I know that all elements in a ICollection instance are of type, string, is there a handy utility function to convert this Collection to a array string[]? Thanks, Ricky.
ICollection has "Add" method (see in screenshot 2). So, there is not any index as a parameter to insert or remove element at a particular index. The ArrayList implements the ICollection interface that supports iteration of the collection types. So, use the foreach and the for loop to iterate an ArrayList. The Count property of an ArrayList returns the total number of elements in an ArrayList.

Also, the ICollection interface doesn't have an Add method -- you'll need something that implements IList or IList for that. 0x00000000 (00000) 48454144 202f4869 746d616e 50726f2e HEAD /HitmanPro.
