AssemblyName.SetPublicKeyToken Method

Sets the public key token, which is the last 8 bytes of the SHA-1 hash of the public key under which the application or assembly is signed.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

public:
void SetPublicKeyToken (
	array<unsigned char>^ publicKeyToken
)
public void SetPublicKeyToken (
	byte[] publicKeyToken
)
public function SetPublicKeyToken (
	publicKeyToken : byte[]
)

Parameters

publicKeyToken

A byte array containing the public key token of the assembly.
