	DSAParameters parameters


Type: System.Security.Cryptography.DSAParameters

The parameters for DSA.


The cryptographic service provider (CSP) cannot be acquired.


The parameters parameter has missing fields.

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

			//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.  

		catch(CryptographicException e)
			//Catch this exception in case the encryption did
