This article introduces the knowledge of "how to use C# generic arrays". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

C # generics and arrays in C # 2.0, an one-dimensional array with a lower bound of zero automatically implements IList. This allows you to create generic methods that iterate through arrays and other collection types using the same code. This technique is mainly useful for reading data in a collection. The IList interface cannot be used to add or remove elements from an array; if you try to call an IList method (such as the RemoveAt of an array) in this context, an exception will be thrown. The following code example shows how a single generic method with an IList input parameter iterates through both a list and an array, in this case an array of integers.

C # generics and array codes

Class Program {static void Main () {int [] arr = {0,1,2,3,4}; List list = new List (); for (int x = 5; x < 10; x +) {list.Add (x);} ProcessItems (arr); ProcessItems (list) } static void ProcessItems (IList coll) {foreach (T item in coll) {System.Console.Write (item.ToString () + ");} System.Console.WriteLine ();}}

Note when using C # generics and arrays

Although the ProcessItems method cannot add or remove items, for T [] within ProcessItems, the IsReadOnly property returns False because the array itself does not declare the ReadOnly attribute.
