AssemblyName.GetPublicKey AssemblyName.GetPublicKey AssemblyName.GetPublicKey AssemblyName.GetPublicKey Method

Definición

Obtiene la clave pública del ensamblado.Gets the public key of the assembly.

public:
 cli::array <System::Byte> ^ GetPublicKey();
public byte[] GetPublicKey ();
member this.GetPublicKey : unit -> byte[]
Public Function GetPublicKey () As Byte()

Devoluciones

Byte[]

Matriz de bytes que contiene la clave pública del ensamblado.A byte array that contains the public key of the assembly.

Excepciones

Se ha proporcionado una clave pública (por ejemplo, mediante el método SetPublicKey(Byte[])), pero no se ha proporcionado ningún token de clave pública.A public key was provided (for example, by using the SetPublicKey(Byte[]) method), but no public key token was provided.

Ejemplos

En el ejemplo siguiente, se emite un ensamblado dinámico y lo guarda en el directorio actual.The following example emits a dynamic assembly and saves it to the current directory. Cuando se crea el ensamblado, el SetPublicKey método se usa para asignar una clave pública de ensamblado.When the assembly is created, the SetPublicKey method is used to give the assembly a public key. El GetPublicKey método, a continuación, se usa para recuperar la clave pública, que se muestra en la consola.The GetPublicKey method is then used to retrieve the public key, which is displayed to the console.
