Great reply.

This is not just a "useful answer", and it is not just a five, it is unquantifiable.
I would take off my hat if I had one...

I didn't get it either. Perhaps he's in his own little world. Laugh | :laugh:

I agree with your earlier post, that's a great response from Mike Dimmick. I was so impressed I went back and voted!

Sorry. I forgot I changed my sig, and I don't read my own sig when I proofread my messages...
Thanks for the support!

BTW: I'm just asking to give back what we had before, that hardly qualifies as a revolution, does it?

Did the citizens in Boston sit back and allow the English to force them to drink their nasty over priced tea?
NO! they dressed up as native Americans, to which fooled not even the British, and dumped that team into the harbor!

Did the French sit back and let the Queen tell them to eat cake?
NO! They stood up and said they didn't want to be fat and ugly and killed the Queen and King then hired a short, fat, and ugly evil dictator to take over 90% of Western Europe...

Did the Cubans sit back and wait for Castro to die? (well that's debatable at the moment)
NO! they formed a revolution to take down the commies and were slaughtered and captured in huge numbers! They just wished to make Cuba to be the way it was before the commies took over.

Did the protestors in Tiananmen Square sit back and let the guys in tanks tell them what to do?
NO they stood their ground and were abruptly squashed by those giant tanks.

I tell you sir, that our fight against the oppression by our kind, generous, and caring site builders and administrators by disallowing score votes of 2, 3, and 4 on Questions/Answers is also a Revolution.

C# compiler expand our code?

1-May-08 21:18

Thanks Mike!

Great!!!!!!

In GC, if gen2 collection is decided to run, then gen2 collection has to wait for gen1 collection complete, and gen1 has to wait for gen0 collection complete?

Hello everyone,

How could we see the C# compiler expand our code (I mean at source code level, not using ILDasm to see at IL level or using Diassembly at native assembly code level)?

For example, this is how foreach is expanded in C#.

thanks in advance,
George

One way would be to write simple code, then use Reflector[^] to browse the resultant code.

The using statement is the other one that is just some syntactic sugar, it just builds code you could write just as easily, although I think it's a cool thing to use it.

Thanks Christian,

I have just tried, but no expansion for the following code, why?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {

        static void Main(string[] args)
        {
            int[] array = new int[100];
            foreach (int p in array)
            {
                Console.WriteLine (p);
            }
        }
    }
}

George

Dunno, but if that doesn't work, then I guess all you can do is look at the MSIL, or trust what the books tell you it expands to.

Could you do me a favor to see whether reflector works for you?

I would assume you don't see the full expansion because reflector is clever enough to recognise the IL pattern and display the c# that would have formed this. If you switch reflector to IL mode, you will see the raw IL that the C# compiles to. IIRC the C# compiler generates fields and things in IL with < and > signs in their names, which aren't allowed in c#, so there is no risk of a clash.

For example, try using the automatic properties feature of c# 3.0. If you look at it in reflector, you'll see in the IL it's generated a field called something like <myproperty>k_BackingField. Using the '<' signs mean that there's not a risk of the auto generated backing field clashing with any of your fields. But if you switch reflect to C# mode, it'll give you the original automatic property definition. This is reflector recognising the pattern and reversing it back to the original c',

The way to do it is write the C# for a foreach, and also the c# for a for loop, and then compare the IL generated by each.

Thanks Simon,

Do you mean C# will expand at IL level, not source code level?

regards,
George

Simon P Stevens2-May-08 9:37

Simon P Stevens

2-May-08 9:37

Yes, you right the source code, will be compiled to IL, which is expanded out, as IL doesn't have a foreach statement.

what reflector does is convert that IL back to C#, but because reflector is quite clever it recognises the IL that is there performs the same functions as a foreach loop would, so when it converts it back to c#, it includes a foreach loop.

Is there any online resource about IL language Spec or step by step learning resource? I feel IL is of much difference compared with native assembly language. Smile | :)

// Save the stream to disk
System.IO.FileStream newFile = new System.IO.FileStream(Server.MapPath(sSavePath + sFilename), System.IO.FileMode.Create);
newFile.Write(myData, 0, myData.Length);
newFile.Close();
TextWriter tw = new StreamWriter("d://fyp//images//saved images//info.txt");

// write a line of text to the file
tw.WriteLine("txtFName.txt*txtLName*IDTextBox*" + sSavePath + sFilename);

// close the stream
tw.Close();

on the
TextWriter tw = new StreamWriter("d://fyp//images//saved images//info.txt");
how do i specify the directory so that it will save to /images on my project folder? without specifying the exact location?

also on the
tw.WriteLine("txtFName.txt*txtLName*IDTextBox*" + sSavePath + sFilename);
the result on the notepad is that it writes exactly the same text to the notepad... how do i make it so that i'll save whatever I input onto my textboxes?

The same as you do for the stream, server.mappath.

By removing the quotes. txtFName.Text + " " + txtLName.Text + " " + IDTextBox.Text

thanks.. the second one works..
however.. for the first one... is this the correct code?

TextWriter tw = new StreamWriter("Server.MapPath/images/info.txt");

also.. if i write 2 or more image files... it will overwrite the exisiting one... how do i make it so that it will write onto next line in my textfile
