That looks great Nigel thanks.
And the null-coalescing operator checks both null and empty?

Subject: RE: Check null or empty on it field
Rather than pull the title out to a seperate string variable and then check on
it, I would use something like:
string iTitle = (string)(spListItem[Title] ?? No Title);
string iDesc = (string)(spListItem[Description] ?? No description);
I believe casting the field value to string is more efficient then using a
ToString function, and using the null-coalescing operator is more efficient
then a seperate if statement (though I am prepared to be shouted down over
this :)
Also, I think it is a lot neater in the code, and the same form can be used for
different datatypes:
DateTime someDate = (DateTime)(item[Date Field Name] ?? DateTime.MinValue);
Cheers,
Nigel

Subject: Check null or empty on it field
Hi all,
I'm trying to put some checks in place to avoid exceptions when a field has no
value. I had tried null but it didn't seem to be enough. I'm now trying the
following but continue to get an exception when a field in any item is empty.
Is there a more robust way to do this? Check length as well, or instead??
// Check the value for each string and supply a defualt if none exists
if (string.IsNullOrEmpty(iTitle))
{
iTitle = No Title;
}
if (string.IsNullOrEmpty(iDesc))
{
iDesc = No description;
}
Kind regards,
Paul Noone
