I'm not sure what part you are stuck with so I shall explain all the parts I think I can see.

It looks like you are looking for the indexer syntax on arrays.

The code you may want is:

if (NewArray.Length == 3 && NewArray[1].ToLower() == "dddd")

Note the square brackets [] indexing into the array. Regular C# arrays exposes an int indexer. Once indexed, the dot-notation will give you access to the type inside the array, here I assume that the array is a string[], hence we can do NewArray[1].<string members here>.

Note also that array indexing in C# is zero-based, so 0 is the first element of the array and NewArray.Length - 1 is the last element. Your [1] may not be correct unless of course you intend on accessing the second array item.

As a side note, using ToLower is not the only way to get case-insensitive comparisons, you can also do the following:

string.Compare(NewArray[1], "dddd", true) == 0

The string.Compare documentation shows the ignoreCase argument. I'm not in any way trying to say my suggestion is best practice.

You're looking for ToLower() method?

if (newArray.Length == 3 && newArray[1].ToLower() == "dddd") ...
