![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetBaseException | When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetObjectData | Sets the SerializationInfo with information about the exception. (Overrides Exception::GetObjectData(SerializationInfo, StreamingContext).) |

The LicenseManager::Validate method throws LicenseException when a component cannot obtain a valid license. This occurs when a component is either not licensed, or is licensed but cannot be granted a valid license.

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 shows how to catch a LicenseException and interpret its content. In the sample, the application calls the Validate method for a System.Windows.Forms::Form that is not licensed. Upon catching the exception, the sample fetches the respective error message, the type of component that was not granted a license, the stack trace, and the origin of the exception.
This example requires that you have specified the LicenseProvider by marking the System.Windows.Forms::Form with a LicenseProviderAttribute attribute. For more information on how to do this, see the LicenseManager class.
