X509Store Class
.NET Framework 3.0
Represents an X.509 store, which is a physical store where certificates are persisted and managed. This class cannot be inherited.
Namespace: System.Security.Cryptography.X509Certificates
Assembly: System (in system.dll)
Assembly: System (in system.dll)
The following code example opens an X.509 certificate store, adds and deletes certificates, and then closes the store. It assumes that you have three certificates to add to and remove from a local store.
