Decode(Byte[])	將已編碼的 SignedCms 訊息進行解碼。
Decode(ReadOnlySpan<Byte>)

Decode(Byte[])

來源:

SignedCms.cs

將已編碼的 SignedCms 訊息進行解碼。

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

public void Decode (byte[] encodedMessage);

member this.Decode : byte[] -> unit

Public Sub Decode (encodedMessage As Byte())

參數

encodedMessage

Byte[]

位元組值陣列，代表要解碼之已編碼的 CMS/PKCS#7 訊息。

例外狀況

ArgumentNullException

encodedMessage 為 null。

CryptographicException

無法成功解碼 encodedMessage。

範例

下列範例顯示方法在驗證訊息簽章 SignedCms 的過程中的位置 Decode 。 在此範例中，訊息內容不會中斷連結，因此訊息內容會包含在訊息中 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)

下列範例顯示方法在驗證訊息簽章 SignedCms 的過程中的位置 Decode 。 在此範例中，訊息內容會中斷連結，因此訊息內容必須獨立于訊息外驗證 SignedCms 。

// 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)

備註

這個方法會使用從成功解碼取得的資訊來重設物件的所有成員變數。
