XMl Linq question

I am trying to find a first element from an xml file using the
following code
XElement t = xml.Descendants ("Element").Fir st();

This works fine, but when there is no result set ofcourse the first
method call bombs. I can always split the statement into two and check
if there are any elements available before I pick the first element.
Is it possible to do it in a single statement?

something like the following

from e1 in xml.Decendants( "Element")
select top 1;

Thanks.

Use
XElement t = xml.Descendants ("Element").Fir stOrDefault();
that way t will be the first 'Element' descendant or nul if there is none.

In Linq, you can apparently get a meaningful body from and expression's .ToString(); random question - does anybody know if linq also includes a parser? It just seemed it might be a handy way to write a safe but easy implementation (i.e. no codedom) for an IBindingListView.Filter (by compiling to a Predicate<T>). Anybody know if this is possible at all? Marc

I recently stumbled across a pretty interesting LINQ to SQL question and wonder, whether anybody might have an answer. (I'm doing quite some increasing LINQ evangelism down here in Germany.). Assume I want to select rows from a database and check whether a specific column contains keywords from a list of keywords. The following works just fine: List<stringsearchTerms = new List<string>() { "Maria", "Pedro" };

Hi all: after reading different places/sites about linq... I ran into these questions: 1. What framework do we need to run linq ? (does it depend on what version of visual studio we have?) how about vs2008? is it different name space or framework for linq xml or linq sql? ( 2. do we need to have references to what linq's dlls. or namespaces? system core? 3. what name spaces are needed?

I am a bit conservative type and usually give some time for technology to mature before starting to try it. Today my question is Linq. To start using it or not. So here is the voting questions. 1. It speeds up development. Yes or No? 2. It makes programs easier to code and read. Yes or No? 3. Perfomance is the same (or comparable) comparing Linq with MsSql and ADO.NET

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
