アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Overrides Function
 ExportParameters ( _
    includePrivateParameters As Boolean _
) As RSAParameters

Visual Basic (使用法)

Dim instance As RSACryptoServiceProvider
Dim includePrivateParameters As Boolean
Dim returnValue As RSAParameters

returnValue = instance.ExportParameters(includePrivateParameters)

public override RSAParameters ExportParameters (
    bool includePrivateParameters
)

C++

public:
virtual RSAParameters ExportParameters (
    bool includePrivateParameters
) override

public RSAParameters ExportParameters (
    boolean includePrivateParameters
)

JScript

public override function ExportParameters (
    includePrivateParameters : boolean
) : RSAParameters

パラメータ

使用例

RSACryptoServiceProvider を使用して作成したキー情報を RSAParameters オブジェクトにエクスポートするコード例を次に示します。

Visual Basic

Try

    'Create a new RSACryptoServiceProvider object. 
    Dim RSA As New RSACryptoServiceProvider()

    'Export the key information to an RSAParameters object.
    'Pass false to export the public key information or pass
    'true to export public and private key information.
    Dim RSAParams As RSAParameters = RSA.ExportParameters(False)


Catch e As CryptographicException
    'Catch this exception in case the encryption did
    'not succeed.
    Console.WriteLine(e.Message)
End Try

try
{
    //Create a new RSACryptoServiceProvider object.
    RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();


    //Export the key information to an RSAParameters object.
    //Pass false to export the public key information or pass
    //true to export public and private key information.
    RSAParameters RSAParams = RSA.ExportParameters(false);


}
catch(CryptographicException e)
{
    //Catch this exception in case the encryption did
    //not succeed.
    Console.WriteLine(e.Message);

}

C++

try
{
   //Create a new RSACryptoServiceProvider Object*.
   RSACryptoServiceProvider^ RSA = gcnew RSACryptoServiceProvider;
   
   //Export the key information to an RSAParameters object.
   //Pass false to export the public key information or pass
   //true to export public and private key information.
   RSAParameters RSAParams = RSA->ExportParameters( false );
}
catch ( CryptographicException^ e ) 
{
   //Catch this exception in case the encryption did
   //not succeed.
   Console::WriteLine( e->Message );
}

try {
    // Create a new RSACryptoServiceProvider object.
    RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();

    // Export the key information to an RSAParameters object.
    // Pass false to export the public key information or pass
    // true to export public and private key information.
    RSAParameters rsaParams = rsa.ExportParameters(false);
}
catch (CryptographicException e) {
    // Catch this exception in case the encryption did
    // not succeed.
    Console.WriteLine(e.get_Message());
}
