public CertificateStore(
	string storeName,
	CertStoreType storeType,
	string pfxPassword
)

Public Sub New ( 
	storeName As String,
	storeType As CertStoreType,
	pfxPassword As String
)

Parameters

storeName

Type: SystemString
The name of the certificate store or the filename if the store is a file.

storeType

Type: MailBee.SecurityCertStoreType
The type of the certificate store.

pfxPassword

Type: SystemString
PFX (.P12, PKCS #12) password if storeType is Pfx; otherwise, can be a null reference (Nothing in Visual Basic).

Only Memory stores can be created. Other stores can only be opened. It's possible, however, to create a memory store and then save it into a file using SaveToFile(String, CertStoreFileType, String) method. To create a new system store, use RegisterSystemStore(String, RegistryStoreLocation) method.

If you open a file store and then modify its contents, it won't be updated on disk until you save it back to the file. A system store, however, gets updated immediately in its registry location each time you call any method which modifies this store.

Note
This overload opens system stores which are located in HKEY_CURRENT_USER registry branch only. To open a system store located in another branch of the registry (such as HKEY_LOCAL_MACHINE which is user-independent), use CertificateStore(String, CertStoreType, String, CryptoServiceProvider, RegistryStoreLocation) overload.
