AssemblyName.SetPublicKey(Byte[]) Method
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Sets the public key identifying the assembly.
public:
void SetPublicKey(cli::array <System::Byte> ^ publicKey);
public void SetPublicKey (byte[] publicKey);
public void SetPublicKey (byte[]? publicKey);
member this.SetPublicKey : byte[] -> unit
Public Sub SetPublicKey (publicKey As Byte())
- publicKey
- Byte[]
A byte array containing the public key of the assembly.
The following example emits a dynamic assembly and saves it to the current directory. When the assembly is created, the SetPublicKey method is used to give the assembly a public key. The GetPublicKey method is then used to retrieve the public key, which is displayed to the console.

You must also use the SetPublicKeyToken method to provide a public key token. Otherwise, a SecurityException is thrown when the GetPublicKey method is called.
