I'm sorry for not being precise enough - this must be performed server-side. I updated the question now.

Outstanding solution! Thanks a lot.

Because as I noticed WebBrowser is changing page (its elements) while being inside loop, so I wanted to lock the whole webBrowser1 control, but it doesn't work. My other idea is to use webBrowser1.Stop() just before getting into loop so the elements remain unchanged but I can't figure out way to "resume" it later.

It seems that WebBrowser is changing content while inside for loop. Please see my last answer to Matt T Heffron.

When using foreach it crashes like every 2 minutes on "in elc" (foreach header)
When using for (int i = 0; i < elc.Count - 1; ++i) It crashes less often (every 30 minutes), but still on line:
HtmlElement element = elc[i];

The reason for different frequency of crashing is due to range it exceeds. The usual exception says:
- "Value of '102' is not valid for 'index'. 'index' should be between 0 and 101."
- Value of '103' is not valid for 'index'. 'index' should be between 0 and 101.

Foreach loop throws an exception for both these cases, whilst "for (int i = 0; i < elc.Count - 1; ++i)" for only one of them (exceeded by 2 elements).

I tried both versions with Invoke and with Invoke removed.
HtmlElementCollection.GetEnumerator() method fails to work for the same reason - ArgumentOutOfRange

Using the lock statement doesn't change anything. It seems that website content gets changed during iteration of loop but the lock keyword doesn't work. I already tried: "lock (elc)", "lock (webBrowser1)", "lock (myObject)" and so on...

I'm trying to get rid of this exception for a week and no way to perform it. Maybe you could help with TeamViewer or any other way?

I'll be clear - this solution doesn't work. It makes it happen less often but doesn't solve the problem.

Sorry, I don't understand what you mean and how to fix it. And yes, I don't want the whole loop invoked (I don't know if it works anyway + thread doesn't make sense). I thought about cloning all the HtmlElementCollection but that's almost as difficult as finding how to fix that bug :/

I edited the code in question as shown.
Line:
element = elc[i];
throws sometimes (not always) exception ArgumentOutOfRange.

I will try it out and let you know, however I don't see why this should work since as I said, exception was: "value is 103 and it should be between 0 and 101" so .Count - 1 will make maxValue = 102 which is still beyond the range of <0;101>

EnGiNe.Pl 6-Apr-16 17:36pm View

What context should I show? That's almost all the code I have.

EnGiNe.Pl 6-Apr-16 15:49pm View

I thought I got it... but now I'm not sure at all - You said, get indexed property on UI thread, that's what I did - but it didn't resolve the problem at all. I don't get why the hell the value can't be evaluated at the time the debugger throws an exception?! What other code should I post?

EnGiNe.Pl 6-Apr-16 12:39pm View

for (int i = 0; i < elc.Count; i++)
{
HtmlElement element = null;
element = elc[i];

In the debugger: value is 103 and it should be between 0 and 101, the value of elc.Count can't be evaluated even if I followed your advice and put that invoke inside the code.

I have tried it:
this.Invoke((MethodInvoker)delegate
{
element = elc[i];
});

but still the same exception... ArgumentOutOfRange

I actually host the website already, and anyone over the internet can see the website using IP. The problem is how to make some data transmission between the website and the client (some type of chat).
