DSACryptoServiceProvider.ImportParameters Method

Imports the specified DSAParameters.

Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)

public override void ImportParameters (
	DSAParameters parameters
)
public void ImportParameters (
	DSAParameters parameters
)
public override function ImportParameters (
	parameters : DSAParameters
)

Parameters

parameters

The parameters for DSA.

Exception typeCondition

CryptographicException

The cryptographic service provider (CSP) cannot be acquired.

-or-

The parameters parameter has missing fields.

The following code example imports key information to a DSACryptoServiceProvider object from a DSAParameters object.

try
{
    //Create a new DSACryptoServiceProvider object. 
    DSACryptoServiceProvider DSA = new DSACryptoServiceProvider();

    //Export the key information to a DSAParameters object.
    //Pass false to export the public key information or pass
    //true to export public and private key information.
    DSAParameters DSAParams = DSA.ExportParameters(false);

    //Create another DSACryptoServiceProvider object.
    DSACryptoServiceProvider DSA2 = new DSACryptoServiceProvider();

    //Import the the key information from the other 
    //DSACryptoServiceProvider object.  
    DSA2.ImportParameters(DSAParams);


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

}

try {
    // Create a new DSACryptoServiceProvider object. 
    DSACryptoServiceProvider dsa = new DSACryptoServiceProvider();

    // Export the key information to a DSAParameters object.
    // Pass false to export the public key information or pass
    // true to export public and private key information.
    DSAParameters dsaParams = dsa.ExportParameters(false);

    // Create another DSACryptoServiceProvider object.
    DSACryptoServiceProvider dsa2 = new DSACryptoServiceProvider();

    // Import the the key information from the other 
    // DSACryptoServiceProvider object.  
    dsa2.ImportParameters(dsaParams);
}
catch (CryptographicException e) {
    // Catch this exception in case the encryption did
    // not succeed.
    Console.WriteLine(e.get_Message());
}
