[Help] C# Sharepoint:: Linkbutton[] (Childcontrols)

i resolved my latest problem of accesing the active directory... since the same values are in my old project with the SQL database that's linked with the active directory but yeah... i have an error when i want to create an linkbutton array instead of a simple string list...

here is the code and where the error is located i narrowed it down as much as possible:

some people have this same bug with .net too...
[php]namespace FaceBook_app
{
public class FaceBook_Code : Microsoft.SharePoint.WebPartPages.WebPart
{
facebookDirectoryDataContext FBAccs = new facebookDirectoryDataContext();

Table<Badge> ACC;
List<Badge> Member;
//public LinkButton[] Test;
HtmlTextWriter writa;

public FaceBook_Code()
{
ACC = FBAccs.Badges;
Member = (from aws in ACC orderby aws.Bezoeker select aws).ToList();
//Test = new LinkButton[Member.Count];
}

protected override void CreateChildControls()//Problem #1 :: VAL = NULL @ <BR> (TRY/CATCH?)//#2 :: Object reference not set to an instance of an object. = (!no button eventhandler, Crashes when 1 codeline gets filled in, curently null entry?)
{
/*
try
{*/
LinkButton[] Test = new LinkButton[Member.Count];
for (int i = 0; i <= this.Member.Count - 1; i = i + 2)
{
Test[i].Click += new EventHandler(Test_Click);
Test[i].Text = Member[i].Bezoeker;
this.Controls.Add(Test[i]);
if (i + 1 < Member.Count)
{
Test[i].Text = Member[i].Bezoeker;
Test[i+1].Click += new EventHandler(Test_Click);
this.Controls.Add(Test[i + 1]);
}
else
{
try{}
catch(Exception a)
{
writa.WriteLine(a);
}
}
}/*
}
catch (*********enceException nre)
{

writa.WriteLine("EventHandler Creation failed");
writa.WriteLine(nre);
}*/
}

public override void RenderControl(HtmlTextWriter writer)
{
Add_Table(writer);
writer.Write("change val");

try

for (int i = 0; i <= this.Member.Count - 1; i = i + 2)
{
try

//Test[i].Text = Member[i].Bezoeker;
writer.RenderBeginTag(HtmlTextWriterTag.Tr);

}

public void Test_Click(object sender, EventArgs e)
{

try
{
writa.WriteLine("Activated an button.");
}
catch(*********enceException nre)
{
writa.WriteLine(nre);
}
}
[/php]

this code works without any request for an button and without the childcontrolls. > childcontrols is the first line it fails.. says its NULL?? I added an Field == null statement... i now obtained the error:
