SignedCms.Decode 方法

定义

命名空间:

System.Security.Cryptography.Pkcs

程序集:

System.Security.Cryptography.Pkcs.dll

重载

Decode(Byte[])	对已编码的 SignedCms 消息进行解码。
Decode(ReadOnlySpan<Byte>)

Decode(Byte[])

对已编码的 SignedCms 消息进行解码。

public:
 void Decode(cli::array <System::Byte> ^ encodedMessage);

public void Decode (byte[] encodedMessage);

member this.Decode : byte[] -> unit

Public Sub Decode (encodedMessage As Byte())

参数

encodedMessage

Byte[]

表示待解码的编码 CMS/PKCS #7 消息的字节值数组。

例外

ArgumentNullException

encodedMessage 为 null。

CryptographicException

encodedMessage 无法成功解码。

示例

以下示例演示方法在验证邮件签名SignedCms的过程中的位置Decode。 在此示例中，消息内容未分离，因此消息内容包含在消息中 SignedCms 。

// Create a new, nondetached SignedCms message.
SignedCms signedCms = new SignedCms();

// encodedMessage is the encoded message received from
// the sender.
signedCms.Decode(encodedMessage);

// Verify the signature without validating the
// certificate.
signedCms.CheckSignature(true);

' Create a new, nondetached SignedCms message.
Dim signedCms As New SignedCms()

' encodedMessage is the encoded message received from 
' the sender.
signedCms.Decode(encodedMessage)

' Verify the signature without validating the 
' certificate.
signedCms.CheckSignature(True)

以下示例演示方法在验证邮件签名SignedCms的过程中的位置Decode。 在此示例中，消息内容是分离的，因此必须独立于 SignedCms 消息验证消息内容。

// Create a ContentInfo object from the inner content obtained
// independently from encodedMessage.
ContentInfo contentInfo = new ContentInfo(innerContent);

// Create a new, detached SignedCms message.
SignedCms signedCms = new SignedCms(contentInfo, true);

// encodedMessage is the encoded message received from
// the sender.
signedCms.Decode(encodedMessage);

// Verify the signature without validating the
// certificate.
signedCms.CheckSignature(true);

' Create a ContentInfo object from the inner content obtained 
' independently from encodedMessage.
Dim contentInfo As New ContentInfo(innerContent)

' Create a new, detached SignedCms message.
Dim signedCms As New SignedCms(contentInfo, True)

' encodedMessage is the encoded message received from 
' the sender.
signedCms.Decode(encodedMessage)

' Verify the signature without validating the 
' certificate.
signedCms.CheckSignature(True)

注解

此方法使用从成功解码中获取的信息重置对象的所有成员变量。
