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

public byte[] RawData { get; }
/** @property */
public byte[] get_RawData ()

public function get RawData () : byte[]

Not applicable.

Property Value

The raw data of the certificate as a byte array.

The following code example creates a command-line executable that takes a certificate file as an argument and prints various certificate properties to the console.
