Colletion To List

Ert Tre

Hello Forum,

I have a collection class (inherited from System.Collections.CollectionBase). I want to return the contents in a list<>. I do this with the following function:

public List Clone()

{

	List objMyCustomBlockList = new List();

	MyCustomBlock[] objMyCustomBlockArray= new MyCustomBlock[this.List.Count];

	this.List.CopyTo(objMyCustomBlockArray, 0);

	objMyCustomBlockList.AddRange(objMyCustomBlockArray);

	return objMyCustomBlockList;

}

Is there a faster way of doing this (performance)?

Is there a more elegant way of writing this code (less code)?

Thank you.

Looks good tome, except I didn't get the "this" part of the code. Is this an extension method?

HelloManas Mohapatra,
I don't think that answers my questions.
Thank you for the response.

If you want to clone the list of object then you can use like following code:
List<MyCustomBlock> lstStudent = books_1.ConvertAll(x => new MyCustomBlock
{
   Id=x.Id,
   Name=x.Name,
   Description=x.Description
});

// Or

List<MyCustomBlock> books_3 = new List<MyCustomBlock>(books_1);
