CspKeyContainerInfo Constructor

Initializes a new instance of the CspKeyContainerInfo class using the specified parameters.

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

public CspKeyContainerInfo(
	CspParameters parameters
)

Parameters

parameters
Type: System.Security.Cryptography.CspParameters

A CspParameters object that provides information about the key.

The following code example creates a key container and retrieves information about that container.

using System;
using System.Security.Cryptography;
using System.Text;


public class CspKeyContainerInfoExample

    public static void Main(String[] args)

            // a key container is not created until you call   
            // a method that uses the key.  This example calls 
            // the Encrypt method before calling the 
            // CspKeyContainerInfo property so that a key 
            // container is created.   

            // Create some data to encrypt and display it.
