Questions about NullReferenceException in Linq queries

Hello Werner,

I'm afraid this problem can not be fixed easily, so there's little chance
that it will be fixed in the nearest bugfix releases. You can "watch" the
following issue in our tracker: http://youtrack.jetbrains.net/issue/RSRP-188273
to get notified when it's fixed. Thank you!

Hi,

Using 5.1 I know that there is a bug when dealing with null values in
Linq expressions. For example:

var properties = new[] {"1", null, "3"};
foreach (var value in properties.Where(value => value !=
null).Select(value => value.Trim()))
{
Debug.Write(value);
}
Here I get an error in the "Select" that says value may be nu -
obviously it isn't. So to my question: Will there be a near fix of
this or will it have to wait until the next major release? We have
thousands of Linq queries and this bug is producing thousands of
errors. Of course, the "NullreferenceException" check is something we
don't want to disable.

Or is there a solution - Linq-wise - in the above "Select" that would
make ReSharper validate correct?

Understood, thanks Andrey. I will keep an eye out for the fix.

I have to ask :)

Isn't there a way to get R# to ignore these null reference errors in linq? We are having thousands of errors/warnings due to this, but we don't want to ignore *all* null reference errors/warnings. Any "hack" to get R# to ignore them in Linq?
