Show Modal dialog

How can I create a modal dialog in winform without creating a new taskbar item?

I'm instanciating my modal as:

FrmDialog dialog = n开发者_开发知识库ew FrmDialog();
dialog .ShowDialog(this);

Edit the showInTaskbar property:

dialog.ShowInTaskbar = false;

Set the ShowInTaskBar property to false.

var dialog = new FrmDialog();
dialog.ShowInTaskbar = false;
dialog.ShowDialog();

dialog.ShowInTaskbar = false;
