Hello,
Is there a (relatively simple) way to know whether the compiler has inlined my method? (Actually I want to make sure that it did...)
|
|

|

No, and you will have no guarantee that a function will be inlined. Actually, it's not job of the C# compiler, but rather the JIT that does the inlining at runtime, if it decides to do so. But you have no control over it and can not rely on a function being inlined.

Well, there is one sure fire way, but that involves getting hired by Microsoft in a position on the CLR team and writing code to do this.

The first thing I'd do with this new job would be to introduce some kind of forceinline directive

That would be nice.

Well, thanks a lot. But since, I'm very concerned about performance, I'd appreciate more of your expertise. There are some methods that I'm writing just for modularity reasons. Each is just a single line of code. For example:
class X {
public int Value { get { return getExternalValue(); } }
private int getExternalValue() {
}
}I am thinking that the JIT should be intelligent enough to actually inline both methods. But is this assumption true? Or should I inline the method myself?
Many thanks to all helpful guys here in CP!
I really appreciate your help. ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Nobody (apart from the Microsoft CLR team) knows exactly under which circumstances the JIT optimizes code. While the JIT probably is intelligent enough to see that the function can be inlined, it still might decide not to do so based on other parameters.
So in your case, if you're really concerned about performance you probably should inline it yourself - it'll always be a compromise between modularity/readability and performance.
This article[^] and this blog entry[^] talk a bit about the JIT method inlining, you may want to take a look at them.

You are micro-optimising. In any normal situation it will not make any real difference if the method is inlined or not.
If you really need that litte extra performance, you should probably not only inline this method, but the method that you are calling also...
Despite everything, the person most likely to be fooling you next is yourself.

You're right. I'm just trying to write micro-optimized code that is maintainable to some level. I'm introducing a wrapper layer for some external functions, but performance is at premium, so I'm trying to optimize it as much as possible, without exposing the external interfaces to other layers.
Many thanks to all helpful guys here in CP!
I really appreciate your help.

If you really need to optimise the code so much that you need the methods to be inlined, you are way beyond maintainable code. If you are still thinking of maintainable code, you should not bother with the tiny performance difference that inlining methods means.
Despite everything, the person most likely to be fooling you next is yourself.

Hello everyone,
I am reading WSDL and SOAP spec and my purpose is to learn Spec/protocol details, for example, the component model of WSDL/SOAP and meaning/relationship between sections of messages/XML.
Now I am learning from Spec, but find it so boring to learn and not very readable.
http://www.w3.org/TR/wsdl20/
http://www.w3.org/TR/2007/REC-soap12-part0-20070427/
My question is whether there is more readable documents or turorials? Or learning web sites?
thanks in advance,
George

i don't think that was the correct way to implement because it does not asks for password.

Hello,
I noticed today that the System.Runtime.InteropServices.Marshal class has overloads of the Copy method in the form: Copy(IntPtr source, int[] destination, int startIndex, int length);, but there are no overloads for unsigned data (e.g. uint). I wonder why?
Thanks in advance.
|
|
|
|
|
Perhaps because uint type is not CLS[^]-compliant.
|
|
|
|
|
Thanks. But I'm wondering, since I'm creating a class library with methods that take uint, does this mean the library will not be usable except in C#?
