I have a structur in a class level like this

public struct sunData

{

public int location;

public string url_address;

public string mac_address;

}

..........................

Inside one of the methods in the class I use a LiatArray like this

ArrayList SunsCollection = new ArrayList();

and I assin the following 3 values inside a loop and it works fine.

sunData sundata;

sundata.location = (int)SunsdataRow["LOCATION"];

sundata.url_address = SunsdataRow["IP_ADDRESS"].ToString();

sundata.mac_address = SunsdataRow["MAC_ADDRESS"].ToString();

// add to the ListArray collection

SunsCollection.Add(sundata);

Problem is that I can't print the data from the listarray into a
consol or a logger like this

Console.WriteLine(SunsCollection[0].url_address );

I get a the following error

Error 80 'object' does not contain a definition for 'location'

Can someone help me please?

You would need to cast the object you get from the ArrayList to the
type you need. For example:

string address = ((SunData)sunsCollection[0]).UrlAddress;

Or use a List<SunData>.
For example:
using System.Collections.Generic;

List<SunData> sunsList = new List<SunData>();

// add some SunData objects to the list...

string address = sunsList[0].UrlAddress;
