Hi Zheng,
There are a few ways to do that.
>From capi you can call CertGetCertificateContextProperty() with
CERT_KEY_PROV_INFO_PROP_ID and if you get a valid result, you know
that cert has a keycontainer/private key associated with it.
>From the returned PCRYPT_KEY_PROV_INFO, get the member via:
PCRYPT_KEY_PROV_INFO ->ContainerName
Approach for .NET uses identical calls you would use in CryptoAPI.
See .NET "KeyPal" source code and function GetCertContainernames() therein:
