Namespace:  System.Security.Cryptography.X509Certificates
Assembly:  mscorlib (in mscorlib.dll)

public X509Certificate(
	string fileName,
	string password,
	X509KeyStorageFlags keyStorageFlags
)

Parameters

fileName
Type: System.String
The name of a PKCS7 signed file.
password
Type: System.String
The password required to access the X.509 certificate data.
keyStorageFlags
Type: System.Security.Cryptography.X509Certificates.X509KeyStorageFlags
A bitwise combination of the enumeration values that control where and how to import the certificate.

ExceptionCondition
CryptographicException

An error with the certificate occurs. For example:

  • The certificate file does not exist.

  • The certificate is invalid.

  • The certificate's password is incorrect.

ArgumentException

The fileName parameter is null.

If you create an X509Certificate certificate by specifying a PKCS7 signed file store for fileName, the X509Certificate is created for the certificate that signed the store rather than for any of the certificates within the store.
