When you create a component that you want to license, you must specify the LicenseProvider by marking the component with a LicenseProviderAttribute.
Use the LicenseProvider property to get the Type of the LicenseProvider.

The following code example uses the LicFileLicenseProvider as the license provider for MyControl.
The next code example creates an instance of the MyControl class. Then, it gets the attributes for the class, and prints the name of the license provider used by myNewControl.
public static int Main() { // Creates a new component. MyControl myNewControl = new MyControl(); // Gets the attributes for the component. AttributeCollection attributes = TypeDescriptor.GetAttributes(myNewControl); /* Prints the name of the license provider by retrieving the LicenseProviderAttribute * from the AttributeCollection. */ LicenseProviderAttribute myAttribute = (LicenseProviderAttribute)attributes[typeof(LicenseProviderAttribute)]; Console.WriteLine("The license provider for this class is: " + myAttribute.LicenseProvider.ToString()); return 0; }
