Thanks for all the different methods!
I’ve had no luck with the non-coalescing or ternary operators. Checking for
null value simply doesn’t seem to cut it.
Finally cracked it with Salaman’s example.
string iTitle = "Untitled";
if (listItem["Title"] != null &&
SPEncode.HtmlEncode(listItem["Title"].ToString()) != string.Empty &&
!string.IsNullOrEmpty(listItem["Title"].ToString()))
{
iTitle = listItem["Title"].ToString();
}
Is it just me that goes through all this pain trying to achieve the most basic
needs?

This is the way I go:
country = (item["Country"] ?? "No Country").ToString();
All in one line, neat and easy!

It should work,
if (item["Country"] != null )
{
country = item["Country"].ToString();
}
You can also check this way,
if (item["Country"] != null && SPEncode.HtmlEncode(item["Country"].ToString())
!= string.Empty && !string.IsNullOrEmpty(item["Country"].ToString()))
{
country = item["Country"].ToString();
}

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

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
