NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The following code example creates a DesignerCollection initialized with a specified array of IDesignerHost objects.

// Create a DesignerCollection using a constructor 
// that accepts an array of IDesignerHost objects with  
// which to initialize the array.
DesignerCollection collection = new DesignerCollection( 
    new IDesignerHost[] { designerhost1, designerhost2 } );
