You can decorate an item with this attribute to indicate that it should provide a particular System.Drawing.Design.ToolboxItem. You can determine the type of the ToolboxItem with the ToolboxItemType property, and its name with ToolboxItemTypeName. You can compare against the Default and None values for equality.

public class ToolboxItemAttribute : Attribute {
// Public Constructors
   public ToolboxItemAttribute(bool defaultType);
   public ToolboxItemAttribute(string toolboxItemTypeName);
   public ToolboxItemAttribute(Type toolboxItemType);
// Public Static Fields
   public static readonly ToolboxItemAttribute Default;  // =System.ComponentModel.ToolboxItemAttribute
   public static readonly ToolboxItemAttribute None;  // =System.ComponentModel.ToolboxItemAttribute
// Public Instance Properties
   public Type ToolboxItemType{get; }
   public string ToolboxItemTypeName{get; }
// Public Instance Methods
   public override bool Equals(object obj);  // overrides Attribute
   public override int GetHashCode();  // overrides Attribute
