Question

I am trying to figure out if I have an XmlNodeList object, and Count is greater or equal to 1, will its “Item” object ever be null?

If so, how can I check if it is null before calling its “HasChildNode” property?

if (XmlNodeList.Item(0).HasChildNodes)

Thanks,

No item will never be null in the example you give – usually you would access the items differently though – either by index directly (if you need the index):

XmlNodeList nodes= ...
for (int itr = 0; itr < nodes.Count; itr++)
{
   //do something with nodes[i]
}

or with foreach:

XmlNodeList nodes= ..
foreach (XmlNode node in nodes)
{
   //do something with node
}
