示例1: Main
//引入命名空间
using System;
using System.Security.Cryptography.Xml;
using System.Xml;
using System.IO;
/// This sample used the EncryptedData class to create an encrypted data element
/// and write it to an XML file. It demonstrates the use of CipherReference.

// URI should be Base64-decoded before other processing.

//Create a transform chain and add the transform to it.
