arguments

Hi People,

I've got a method in c# that needs to return a very large array (or any other large data structure for that matter).

Is there a performance gain in using a ref or out parameter instead of the standard return value?

I.e. is there any performance or other gain in using
void function(sometype input, ref largearray)
over
largearray function(sometype input) ?

Thanks in advance!

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
