//Create new X509 store from local certificate store.
X509Store store = new X509Store("MY", StoreLocation.CurrentUser);
store.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadWrite);
//Output store information.
Console.WriteLine ("Store Information");
Console.WriteLine ("Number of certificates in the store: {0}", store.Certificates.Count);
Console.WriteLine ("Store location: {0}", store.Location);
Console.WriteLine ("Store name: {0} {1}", store.Name, Environment.NewLine);
//Put certificates from the store into a collection so user can select one.
X509Certificate2Collection fcollection = (X509Certificate2Collection)store.Certificates;
X509Certificate2Collection collection = X509Certificate2UI.SelectFromCollection(fcollection, "Select an X509 Certificate", "Choose a certificate to examine.", X509SelectionFlag.SingleSelection);
X509Certificate2 certificate = collection[0];
X509Certificate2UI.DisplayCertificate(certificate);
'Create new X509 store from local certificate store.
Dim store As New X509Store("MY", StoreLocation.CurrentUser)
store.Open(OpenFlags.OpenExistingOnly Or OpenFlags.ReadWrite)
'Output store information.
Console.WriteLine("Store Information")
Console.WriteLine("Number of certificates in the store: {0}", store.Certificates.Count)
Console.WriteLine("Store location: {0}", store.Location)
Console.WriteLine("Store name: {0} {1}", store.Name, Environment.NewLine)
'Put certificates from the store into a collection so user can select one.
Dim fcollection As X509Certificate2Collection = CType(store.Certificates, X509Certificate2Collection)
Dim collection As X509Certificate2Collection = X509Certificate2UI.SelectFromCollection(fcollection, "Select an X509 Certificate", "Choose a certificate to examine.", X509SelectionFlag.SingleSelection)
Dim certificate As X509Certificate2 = collection(0)
X509Certificate2UI.DisplayCertificate(certificate)
