X500DistinguishedName.Decode(X500DistinguishedNameFlags) 方法
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
使用由 flag
参数指定的特征对识别名进行解码。
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
参数
指定区分名特征的枚举值的按位组合。
返回
解码的识别名。
例外
证书名称无效。
