RSACryptoServiceProvider.ExportParameters(Boolean) 方法

定義

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

RSA 的參數。

例外狀況

無法匯出金鑰。

範例

下列程式代碼範例會將使用 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
