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.

For more information on licensing, see How to: License Components and Controls.

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.

No code example is currently available or this language may not be supported.
