How to compare the byte array and byte array list?

Question

I have a byte array and a byte list, they both contains same numbers. how should I compare them.

code i am using, but not working:

if (portBuffer.Equals(ret_bytes))
         status = 0;

The following image is captured when i was debugging. they basicly contains same bytes. I know they are belonging to different object, but how to cast them? thanks

See how far you get with SequenceEquals

use the extension method SequenceEqual.

using System.Linq;

//...

if (portBuffer.SequenceEqual(ret_bytes))
         status = 0;

Do you mind explain just a little what is linq? what does it do?

Fernando Over a year ago

Think about linq as a component that allows you to query objects collections, xml, databases etc...In practice, the namespace System.Linq adds a lot of extension methods to allow the querying. So, when you add that using clause, you are making the method SequenceEqual available to all collections that implement IEnumerable.

If you want to use linq, try:

var arraysAreEqual = Enumerable.SequenceEqual(portBuffer, ret_bytes);

I am not at my pc so I cannot tell you if any casting is needed.
