SslStream.IsSigned 屬性

定義

命名空間:

System.Net.Security

組件:

System.Net.Security.dll

來源:

SslStream.cs

取得 Boolean 值，指示使用此資料流傳送的資料是否簽章。

public:
 virtual property bool IsSigned { bool get(); };

public override bool IsSigned { get; }

member this.IsSigned : bool

Public Overrides ReadOnly Property IsSigned As Boolean

屬性值

Boolean

如果資料在傳輸前簽章，則為 true，否則為 false。

範例

下列程式代碼範例示範如何顯示這個屬性的值。

static void DisplaySecurityServices( SslStream^ stream )
{
   Console::WriteLine( L"Is authenticated: {0} as server? {1}", stream->IsAuthenticated, stream->IsServer );
   Console::WriteLine( L"IsSigned: {0}", stream->IsSigned );
   Console::WriteLine( L"Is Encrypted: {0}", stream->IsEncrypted );
   Console::WriteLine( L"Is mutually authenticated: {0}", stream->IsMutuallyAuthenticated );
}

static void DisplaySecurityServices(SslStream stream)
{
   Console.WriteLine("Is authenticated: {0} as server? {1}", stream.IsAuthenticated, stream.IsServer);
   Console.WriteLine("IsSigned: {0}", stream.IsSigned);
   Console.WriteLine("Is Encrypted: {0}", stream.IsEncrypted);
   Console.WriteLine("Is mutually authenticated: {0}", stream.IsMutuallyAuthenticated);
}

Private Shared Sub DisplaySecurityServices(stream As SslStream)
    Console.WriteLine("Is authenticated: {0} as server? {1}", stream.IsAuthenticated, stream.IsServer)
    Console.WriteLine("IsSigned: {0}", stream.IsSigned)
    Console.WriteLine("Is Encrypted: {0}", stream.IsEncrypted)
    Console.WriteLine("Is mutually authenticated: {0}", stream.IsMutuallyAuthenticated)
End Sub

備註

數據簽署有助於保護數據的完整性，也就是協助收件者判斷數據在傳輸時是否遭到竄改。
