Örnekler

Aşağıdaki kod örneği, özel bir araç kutusu öğesi uygulaması için öğesinden ToolboxItem türetilen bir sınıfta yönteminin kullanımını CreateComponentsCore gösterir. Bu kod örneği, sınıfı için ToolboxItem sağlanan daha büyük bir örneğin parçasıdır.

protected override IComponent[] CreateComponentsCore(
    System.ComponentModel.Design.IDesignerHost host, 
    System.Collections.IDictionary defaultValues)
{
    // Get the string we want to fill in the custom
    // user control.  If the user cancels out of the dialog,
    // return null or an empty array to signify that the 
    // tool creation was canceled.
    using (ToolboxItemDialog d = new ToolboxItemDialog())
    {
        if (d.ShowDialog() == DialogResult.OK)
        {
            string text = d.CreationText;

            IComponent[] comps =
                base.CreateComponentsCore(host, defaultValues);
            // comps will have a single component: our data type.
            ((UserControl1)comps[0]).LabelText = text;
            return comps;
