Using list of strings or array of strings

Hi,

I'm migrating from VB6 to VB.NET, in hence my questions below:

I have to write a function that returns array of strings.

How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.

Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?

Thanks in advance

The point of a List is to provide array-like behaviour with the addition of the ability to dynamically grow and shrink. If you need the ability to grow and shrink but you also must have an array then you can use a List and then call its ToArray method when you're done. A List is empty by default so if you create a new List and call ToArray you will get an array with no elements.

Thanks.

Can I use the 'split' function with list? I have to get a string and split it out to dynamic array.

And how do I check if list is empty?

Split returns an array. If you want to split a string and then mess with the results you can use the array to initialise the List. Either pass the array to the constructor when you create the List or else call AddRange and pass the array.

Have you read the documentation for the List class? The answer to that should be pretty obvious if you look at its members.
