Re: [DOTNET] What is the correct way to test for Is Nothing in C#?

Your inclination is correct, and you have nothing to worry about wrt objects overriding == and tests for null references. "!= null" and "== null" are syntactic sugar. No methods are invoked on any object for these particular tests, as you are just testing whether the address stored in the xyz v

Re: [DOTNET] Slow serialization

Some additional information. I'm using a binary formatter not a soap/xml formatter so array optimization should be possible. Thinking this I tried to use a single dim array like "short [] x = new short[512*512]" and that gives very good results. Something about 4,5 ms per array, but

Re: [DOTNET] Slow serialization

Hmm - do you mean that serializing this [Serializable] class MyImage { public short[,] x= new short[512,512]; } results in serializing 256K shorts piece by piece? No array optimizations here? Looking at the SerializationInfo I can't find explicit

Re: [DOTNET] Slow serialization

I am impressed that it is marshaling it in 250ms. You have up to 1/4 million shorts. I might make it faster if I wrote the SerializationInfo prepended with the length of each of these dimensions and only marshal what's required. But that is just the first idea off the top of my head. Thanks,

[DOTNET] Slow serialization

Hi all, I have a class that mainly contains a short[512,512] array and I'd like that class to be value marshalled via .net remoting. Unfortunately the serialization of such an element takes about 250ms on my box - that's quite long isn't it?! Is there any way to tune the performance? I tried to

Re: [DOTNET] What is the correct way to test for Is Nothing in C#?

First of all, you can't overload the != directly, only == (you get != from the == operation). Second, I would say: if (xyz != null) Or if (!(xys == null)) Both are equivalent since you can only overload the == operator (of course the second one is just plain ugly I wouldn't really use it exce
