RSA 系统找不到指定的文件

未测试

System.Security.Cryptography.RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); 

改为

CspParameters RSAParams = new CspParameters();  
RSAParams.Flags = CspProviderFlags.UseMachineKeyStore;  
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(1024, RSAParams);
