winforms - c#: How do i add dropdown menu items at runtime -

When creating a new project, I should be available from this project dropdown. The first project that I create, works, and menu item is kept in the form of a dropdown item, even when I crash the next dropdown item and I set the "object reference to an intent of the object No ".

This line creates an exception: ProjectToolStripMenuItem.DropDownItems.Add (newProject);

ArrayList projects = new ArrayList (); Private zero toolstrip menu item 1_Click (object sender, eventAgps E) {project moldproject = new project (); MoldProject.ProjectName = "Anonymous"; ToolStrip Menu ProjectToolstroke menu item = null; If (projects.kount == 0) {ProjectToolStripMenuItem = new system.windows.form. Tollstrumentmanium (); ProjectToolStripMenuItem.Name = "projectToolStripMenuItem"; ProjectToolStripMenuItem.Size = New System.Downing. Size (44, 20); ProjectToolStripMenuItem.Text = "Anonymous * *"; This.menuStrip1.Items.Add (ProjectToolStripMenuItem); } ToolStripMenuItem newproject = New system.indo.form. Tolstorm menu item (); String name = "aboutToolStripMenuItem" + (project number + 1). Ostring (); Newproject.Name = Name; Newproject.Size = New System Drawing Size (211, 22); Newproject.Text = "Anonymous * *"; ProjectToolStripMenuItem.DropDownItems.Add (newproject); Projects.Add (moldProject); }

toolstrip menu projectToolstrag menu item = zero;

Sorry for the inconvenience the method should have been declared.
