Something like the following should do it for you...

ArrayList namespaces = new ArrayList();
foreach(Type t in System.Reflection.Assembly.GetExecutingAssembly().GetTypes())
{
if(!namespaces.Contains(t.Namespace))
{
namespaces.Add( t.Namespace );
}
}

How to implement tree structure in c# using data structures in C#?

Hi,
I want to build an application that will enable the user to create chart of accounts in nXn(n by n) tree structure. I want to use data structures to do so. The user should be able to not only add new nodes to the tree but also manipulate the data in the tree using references to parent and child nodes(Traversing). Please, help me and provide a solution ASAP.

Thank You.

Basically, i would just use the treeview.

But if not have a struct or class for your node, and within it, have a list of itself:

class Node 
{
    List<node> nodeCollection;
    ...
}

I implemented a simple AVL-tree (that are balanced trees) - the code will only compile in .net 3.5 (because I use some simple LINQ to object statements and a lot of var-declerations) but you should be able to modify it to .net 2.0 without problems (.net 1.1 is not that easy because I use generics for the tree-structures)

I only commented the code in german but I can send you the files if you PM me your adress.

How to clear memory?

I have one programme, which may needs many loops, I found if the loop is too large, then after the running is done, the speed of computer is very slow. Then I want to know is there method to clear the
memory after each loop?

In order to force garbage collection, you would use GC.Collect() but this is an expensive operation. Let the garbage collector work out when it needs to collect from your application. I suspect that your real issue is that you have items that aren't being disposed - thus taking up memory.

Deja View - the feeling that you've seen this post before.

What do you do in the loop ? How much memory do you end up using ? Unless you're creating objects in the loop and not cleaning them up, GC.Collect is going to do precisely zero for you.

Thanks a lot.
related to this quesiton, I have several small questions to trouble you:

1) I use many static variables in my program, does this influence the memory?

2) in the loop I mentioned, I do create several temporal objects such as Dictionary<key, string=""> dic1=new Dictionary<key, string="">, does this will influence the memory? or this can be automatically released when one loop is finished?

thanks again.

You did VB6 before right?

What you are doing is this: you create a NEW invisible(because never shown through .Show) mdi-form and set it's visibility to false.
But you will have to acces the mdi-form-object that is shown in your app!
The easiest way is to use the parent/owner property of your form (you set the owner/mdi-parent of the login-form to the mdi-form) and use this:

<br />
this.Parent.Hide();<br />

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
