c# - C# OutOfMemoryException on array

Question

I'm quite new into C# and right now I'm totally stuck into this function. Any help would be appreciated.

I'm getting an OutOfMemoryException on mess.Add(firstname); I'm pretty sure it's because of an array fault but I can't seem to make it work.

Who can guide me in the right way?

This is my code so far:

 public List<string> SelectEmployee(string pkrelation)
        {
        SDKRecordset inboundSet = IQSDK.CreateRecordset("R_CONTACT", "", "FK_RELATION = " + pkrelation, "");
        inboundSet.MoveFirst();
        string person = inboundSet.Fields["FK_PERSON"].Value.ToString();
        messages.Add(person);

        inboundSet.MoveNext();
        SDKRecordset inboundSet2 = IQSDK.CreateRecordset("R_PERSON", "", "PK_R_PERSON = " + person, "");


        if (inboundSet2 != null && inboundSet2.RecordCount > 0)
        {
            inboundSet2.MoveFirst();              

            do
            {
                string firstname = inboundSet2.Fields["FIRSTNAME"].Value.ToString();
                mess.Add(firstname);

                inboundSet.MoveNext();
            }
            while (!inboundSet2.EOF);
            return mess;


        }

        messages.Add("Error, didn't work.");
        return messages;// null;

You have a typo. You accidentally have inboundSet.MoveNext() so naturally your inboundSet2.EOF is never set to false because you never actually iterate through it. This causes an infinite loop eventually hitting the OutOfMemoryException.

do
{
    string firstname = inboundSet2.Fields["FIRSTNAME"].Value.ToString();
    mess.Add(firstname);

    inboundSet.MoveNext(); // This needs to be inboundSet2!
}
while(!inboundSet2.EOF) //EOF never becomes true causing an infinite loop
