Assembly:  System (in System.dll)

System::Object
  System.ComponentModel::LicenseProvider
    System.ComponentModel::LicFileLicenseProvider

C#
C++
F#
VB
Copy 
[HostProtectionAttribute(SecurityAction::LinkDemand, SharedState = true)]
public ref class LicenseProvider abstract

NameDescription
System_CAPS_protmethodLicenseProvider()

Initializes a new instance of the LicenseProvider class.

NameDescription
System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetLicense(LicenseContext^, Type^, Object^, Boolean)

When overridden in a derived class, gets a license for an instance or type of component, when given a context and whether the denial of a license throws an exception.

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

Notes to Inheritors:

When you inherit from LicenseProvider, you must override the GetLicense method.

See LicFileLicenseProvider for an implementation of this class. For more information on licensing, see How to: License Components and Controls.

The following code example creates a licensed control using the Validate method. It uses a LicenseProvider that is implemented by the LicFileLicenseProvider class.

C#
C++
VB
Copy 
// Adds the LicenseProviderAttribute to the control.

[LicenseProvider(LicFileLicenseProvider::typeid)]
public ref class MyControl: public Control
{
   // Creates a new, null license.
private:
   License^ license;

public:
   MyControl()
   {

      // Adds Validate to the control's constructor.
      license = LicenseManager::Validate( MyControl::typeid, this );

      // Insert code to perform other instance creation tasks here.
   }

public:
   ~MyControl()
   {
      if ( license != nullptr )
      {
         delete license;
         license = nullptr;
      }
   }
};
