定義

命名空間:

System.Security.Cryptography

組件:

System.Security.Cryptography.Csp.dll

組件:

System.Security.Cryptography.dll

組件:

mscorlib.dll

組件:

netstandard.dll

匯出 RSAParameters。

public:
 override System::Security::Cryptography::RSAParameters ExportParameters(bool includePrivateParameters);

public override System.Security.Cryptography.RSAParameters ExportParameters (bool includePrivateParameters);

override this.ExportParameters : bool -> System.Security.Cryptography.RSAParameters

Public Overrides Function ExportParameters (includePrivateParameters As Boolean) As RSAParameters

參數

includePrivateParameters

Boolean

如果要包含私用參數，則為 true；否則為 false。

傳回

RSAParameters

RSA 的參數。

例外狀況

CryptographicException

無法匯出金鑰。

範例

下列程式碼範例會將使用 建立 RSACryptoServiceProvider 的金鑰資訊匯出至 RSAParameters 物件。

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.
    using (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);
}

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
