X500DistinguishedName.Decode(X500DistinguishedNameFlags) 方法
定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
使用 flag
參數所指定的特性,對辨別名稱進行解碼。
public:
System::String ^ Decode(System::Security::Cryptography::X509Certificates::X500DistinguishedNameFlags flag);
public string Decode (System.Security.Cryptography.X509Certificates.X500DistinguishedNameFlags flag);
member this.Decode : System.Security.Cryptography.X509Certificates.X500DistinguishedNameFlags -> string
Public Function Decode (flag As X500DistinguishedNameFlags) As String
參數
列舉值的位元組合,這些值會指定辨別名稱的特性。
傳回
解碼的辨別名稱。
例外狀況
憑證的名稱無效。
