Add MenuItems Dynamically

[MWS]

Hello,

I'm trying to loop through the app.Config file and add the keys from
the app.Config as MenuItems on a MenuStrip. The following line blows
up...

transToolStripM enuItem.DropDow nItems.AddRange (new ToolStripItem[] {
TransMenuItem[TransCount]});

The error that I'm getting is "ArgumentNullEx ceiption was unhandled"
because TransMenuItem[TransCount] is null. Could someone please post a
code snippet out there with an example of how to dynamically add
menuItems to a menustrip? I've seen examples, but all of them have
hard coded declairations of the ToolStripMenuIt ems. I need to loop
though the app.config and declare the ToolStripMenuIt ems.


//TransCount is an integer that equals 5 at this point
ToolStripMenuIt em[] TransMenuItems = new
ToolStripMenuIt em[TransCount];

TransCount = 0;

foreach (string keyname in settings.Allkey s){
transToolStripM enuItem.DropDow nItems.AddRange (new ToolStripItem[] {
TransMenuItem[TransCount]});
TransMenuItems[TransCount].Name = "XXX";
TransMenuItems[TransCount].Text = "XXX";
TransCount++;
}

Are you sure that TransCount in your foreach loop has not exceeded 5 ?
It looks like it has, which is causing the exception.

How many items are there in settings.AllKey s ?
You'll probably find there are more than 5

That's not the problem. when I use watch window in the debugger
TransMenuItems[TransCount] is null. I'm guessing I'm somehow not using
the array correctly because I can get it to work if I replace...

transToolStripM enuItem.DropDow nItems.AddRange (new ToolStripItem[]
{TransMenuItem[TransCount]});

with...

ToolStripMenuIt em TransMenuItem = new ToolStripMenuIt em;
transToolStripM enuItem.DropDow nItems.AddRange (new ToolStripItem[]
{TransMenuItem} );

I never said I was smart.

foreach (string keyname in settings.Allkey s){

TransMenuItems[TransCount] = new ToolStripMenuIt em();

transToolStripM enuItem.DropDow nItems.AddRange (new ToolStripItem[] {
TransMenuItem[TransCount]});
TransMenuItems[TransCount].Name = "XXX";
TransMenuItems[TransCount].Text = "XXX";
TransCount++;

I was missing the declairation in my loop...
