程序集:

netstandard.dll

导入指定的 RSAParameters。

public:
 override void ImportParameters(System::Security::Cryptography::RSAParameters parameters);

public override void ImportParameters (System.Security.Cryptography.RSAParameters parameters);

override this.ImportParameters : System.Security.Cryptography.RSAParameters -> unit

Public Overrides Sub ImportParameters (parameters As RSAParameters)

参数

parameters

RSAParameters

RSA 的参数。

例外

CryptographicException

无法获取加密服务提供程序 (CSP)。

• 或 - parameters 参数具有丢失字段。

示例

下面的代码示例将从 RSAParameters 对象创建的关键信息导入对象 RSACryptoServiceProvider 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 );
   
   //Create another RSACryptoServiceProvider object.
   RSACryptoServiceProvider^ RSA2 = gcnew RSACryptoServiceProvider;
   
   //Import the key information from the other 
   //RSACryptoServiceProvider object.  
   RSA2->ImportParameters( RSAParams );
}
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);

        //Create another RSACryptoServiceProvider object.
        using (RSACryptoServiceProvider RSA2 = new RSACryptoServiceProvider())
        {
        //Import the key information from the other 
        //RSACryptoServiceProvider object.  
        RSA2.ImportParameters(RSAParams);
        }
    }
}
catch (CryptographicException e)
{
    //Catch this exception in case the encryption did
    //not succeed.
    Console.WriteLine(e.Message);
}

Try
    'Create a new RSACryptoServiceProvider object. 
    Using 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)

        'Create another RSACryptoServiceProvider object.
        Using RSA2 As New RSACryptoServiceProvider()

            'Import the key information from the other 
            'RSACryptoServiceProvider object.  
            RSA2.ImportParameters(RSAParams)
        End Using
    End Using

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