Problems with X509Store Certificates.Find FindByThumbprint

Question

I\'m having a problem when I use the method X509Store.Certificates.Find

public static X509Certificate2 FromStore(StoreName storeName, 
                  


        

Answer 1

I ran into this same thing. I couldn't find this answer anywhere in here so I'll post it. It seems for me the X509Store find function just was flat not working. I verified this by a simple for loop and retrieving the cert manually.

  X509Store store = new X509Store(StoreName.Root,StoreLocation.LocalMachine);
        store.Open(OpenFlags.ReadOnly);
        X509Certificate cert = new X509Certificate();
        for (int i = 0; i < store.Certificates.Count; i++)
        {
            if (store.Certificates[i].SerialNumber == "XXXX")
            {
                cert = store.Certificates[i];
            }
        }
