The code you are looking for is here:
ToolStripItem[] tsi = new ToolStripItem[] { successToolStripMenuItem,
successToolStripTextBox };
The other way to do this, without having to manually add the items, is shown below:
ToolStripItem[] tsi = new ToolStripItem[contextMenuStrip.Items.Count];
contextMenuStrip.Items.CopyTo(tsi, 0);
But just so you know, contextMenuStrip.Items
is a Collection
meaning you can address the items in that collection just like you would for an array. For example:
contextMenuStrip.Items[0]
