I follow tutorials word for word but I still get build errors...

I keep doing tutorials and typing stuff out word for word but I always get build errors and I keep having to leave it and go onto the next because I can't fix it myself. I've just followed a video tutorial and watched the guy write it all out, so I copied it, and I got errors.

Errors are as follows:

Error 1 The best overloaded method match for 'int.Parse(string)' has some invalid arguments C:\Websites\Begin\Chapter10\SimpleUserControl\Global.asax 39 25 C:\...\SimpleUserControl\

Error 2 Argument '1': cannot convert from 'method group' to 'string' C:\Websites\Begin\Chapter10\SimpleUserControl\Global.asax 39 35 C:\...\SimpleUserControl\



The errors referred to this piece of code:

void Session_End(object sender, EventArgs e)
{
int userCount = int.Parse(Application.Get("userCount").ToString);
userCount--;
Application.Set("userCount", userCount);
}


The best bit is I have the exact same code in the Session_Start and there are no errors, but I can't see any difference. What is wrong with that?


Thanks in advance

What a pile of poo. I just cut it and pasted it back in and now it works - why would it do that? As if it's not hard enough to learn without errors they go and put some in that aren't even proper ones. :duck:

Code:

---

int userCount = int.Parse(Application.Get("userCount").ToString);

---

You're missing the argument parentheses after ToString. Without them, it is a reference to the ToString method. With them, you are calling the ToString method.

Microsoft don't put errors in deliberately, they have enough as it is.

What's annoying is I put them in after I compared it to the line in the Session_Start which was working, but the errors remained when I tried to run. Then cutting and pasting it back worked.

Thanks for your help and quick response.

Sometimes you have to manually build it before running, by pressing F6 (then F5).

Ah ok, thanks, I didn't know about that one :thumb:
