RSACryptoServiceProvider.ExportParameters(Boolean) 方法

定义

命名空间:

System.Security.Cryptography

程序集:

System.Security.Cryptography.dll

Source:

RSACryptoServiceProvider.Unix.cs

导出 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

参数

includePrivateParameters

Boolean

若要包含专用参数，则为 true；否则为 false。

返回

RSAParameters

RSA 的参数。

例外

CryptographicException

密钥无法导出。

示例

下面的代码示例将使用 RSACryptoServiceProvider 创建的密钥信息导出到 对象 RSAParameters 中。

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
