X509Certificate Constructor (String, SecureString, X509KeyStorageFlags)

Initializes a new instance of the X509Certificate class using a certificate file name, a password, and a key storage flag.

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

new : 
        fileName:string * 
        password:SecureString * 
        keyStorageFlags:X509KeyStorageFlags -> X509Certificate

Parameters

fileName
Type: System.String

The name of a certificate file.

password
Type: System.Security.SecureString

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 a null reference (Nothing in Visual Basic).

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.
