LINQ

equals

I'm actually using a join in linqtosql (via dblinq).

I'm trying to include a regular expression in the join part of the linq query.

from i in collectiona
join j in collectionb on Regex.IsMatch(i.name, j.jokered_name) equals true
(...)

I agree i can push the RegExp check in the where part of the linq query, but i was wondering if it is possible in the join part ? The above code wants an "i equals j" code structure.

One thing i think to perform is overriding Equals() which 'll contains the RegEx.IsMatch() stuff and put a simple i equals j in the join part.

Any suggestions about my problem ?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
