Strange compile problem

I am compiling a simple application and am getting these types of errors:

Type 'EventArgs' is not defined.
Type 'Exception' is not defined.
Type 'Int32' is not defined.
Type 'Type' is not defined.
Name 'Convert' is not declared.

It seems as if the compiler is not including the System.dll (which is obviously referenced in the project). I have tried deleting the bin directory and removing the cache, but nothing helps.

Any ideas?

Thanks,

AndrewLooks like one of the System.* is missing, but is very difficult to tell which one
It looks to me like you haven't declared that you are using the System namespace at the top of your file:

using System;

I have the following references showing:
System
System.Data
System.Design
System.Drawing
System.Web
System.Windows.Forms
System.XML
No, that is not required in vb.

strange compile error!

Hey

asp.net 2.0

This line of code:

MembershipUserCollection onlineUsers = Membership.GetAllUsers;

In this script:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class MasterPages_ContentMaster : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
MembershipUserCollection onlineUsers = Membership.GetAllUsers;
}
}
}

Gives this compile error:
Error 2 Cannot convert method group 'GetAllUsers' to non-delegate type
'System.Web.Security.MembershipUserCollection'. Did you intend to invoke the
method? C:\Documents and Settings\Jeff\My Documents\Visual Studio
2005\WebSites\Helloworld\MasterPages\ContentMaster .master.cs 20 52
C:\...\Helloworld\

The code is placed in a master page...

I don't understand what I'm doing wrong here...

Any suggestions?Its a method, you need some parenthesis there.

You're going to laugh (or cry):
MembershipUserCollection onlineUsers = Membership.GetAllUsers();

Having that "()" there is what you need. This drove me nuts for a while, as
VB.Net doesn't need it and I got in the habit of omitting it.

solved, GetAllUsers is a method, not a property...
