AssemblyName.SetPublicKeyToken 方法

設定公開金鑰語彙基元,即是用於簽署應用程式或組件之公開金鑰 SHA-1 雜湊的最後 8 個位元組。

命名空間:  System.Reflection
組件:  mscorlib (在 mscorlib.dll 中)

public void SetPublicKeyToken(
	byte[] publicKeyToken
)

參數

publicKeyToken
類型:System.Byte[]
位元組陣列,包含組件的公開金鑰語彙基元。

當您藉由呼叫 SetPublicKey 方法設定公開金鑰時,也必須使用 SetPublicKeyToken 方法提供公開金鑰語彙基元。 否則當呼叫 GetPublicKey 方法時,會擲回 SecurityException

下列範例會發出動態組件並將組件儲存至目前的目錄中。 建立組件時,會使用 SetPublicKeyToken 方法來設定組件的公開金鑰語彙基元。 然後會使用 GetPublicKeyToken 方法來擷取此公開金鑰語彙基元,並將它顯示到主控台。
