string myAttribute = String.Empty;
if (configNode.Attributes["someAttribute"] != null)
{
myAttribute = configNode.Attributes["someAttribute"].Value;
}
or to be safer you could use:
if (configNode.Attributes["someAttribute"] != null &&
!String.IsNullOrEmpty(configNode.Attributes["someAttribute"].Value))
{
myAttribute = configNode.Attributes["someAttribute"].Value;
}
