X509SecurityToken.Dispose Method

Releases all resources used by the X509SecurityToken.

Namespace:  System.IdentityModel.Tokens
Assembly:  System.IdentityModel (in System.IdentityModel.dll)

public virtual void Dispose()



Call the Dispose method when you are finished using the X509SecurityToken. The Dispose method leaves the X509SecurityToken in an unusable state. After calling the Dispose method, you must release all references to the X509SecurityToken so the garbage collector can reclaim the memory that the X509SecurityToken was occupying.


Always call Dispose before you release your last reference to the X509SecurityToken. Otherwise, the resources it is using will not be freed until the garbage collector calls the X509SecurityToken object's Finalize method.
