利用wcf传递字节的简单例子

1创建接口   ICalculator

   [ServiceContract(Name = "CalculatorService",Namespace = "liufuchu")]
    public interface ICalculator
    {
        [OperationContract]
        string UpLoadData(byte[] bbbbb);
    }

2 创建计算服务 CalculatorService

    public class CalculatorService :ICalculator
    {
        public string UpLoadData(byte[] bbbbb)
        {
            string fefe = Encoding.UTF8.GetString(bbbbb);
            
            byte[] keyArray = UTF8Encoding.UTF8.GetBytes("0000000000000000");
            byte[] ivArray = UTF8Encoding.UTF8.GetBytes("0000000000000000");

            string roundtrip = DecryptStringFromBytes_Aes(bbbbb, keyArray, ivArray);
            
            DataSet ds = new DataSet();
            //string vv = Encoding.UTF8.GetString(bbbbb);
            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(roundtrip));
            //MemoryStream ms = new MemoryStream(bbbbb);

            ds.ReadXml(ms);
            ms.Close();
            ms.Dispose();
            return "aa";
        }

        static string DecryptStringFromBytes_Aes(byte[] cipherText, byte[] Key, byte[] IV)
        {
            // Check arguments.
            if (cipherText == null || cipherText.Length <= 0)
                throw new ArgumentNullException("cipherText");
            if (Key == null || Key.Length <= 0)
                throw new ArgumentNullException("Key");
            if (IV == null || IV.Length <= 0)
                throw new ArgumentNullException("Key");

            // Declare the string used to hold
            // the decrypted text.
            string plaintext = null;

            // Create an AesCryptoServiceProvider object
            // with the specified key and IV.
            using (AesCryptoServiceProvider aesAlg = new AesCryptoServiceProvider())
            {
                aesAlg.Key = Key;
                aesAlg.IV = IV;

                // Create a decrytor to perform the stream transform.
                ICryptoTransform decryptor = aesAlg.CreateDecryptor(aesAlg.Key, aesAlg.IV);

                // Create the streams used for decryption.
                using (MemoryStream msDecrypt = new MemoryStream(cipherText))
                {
                    using (CryptoStream csDecrypt = new CryptoStream(msDecrypt, decryptor, CryptoStreamMode.Read))
                    {
                        using (StreamReader srDecrypt = new StreamReader(csDecrypt))
                        {

                            // Read the decrypted bytes from the decrypting stream
                            // and place them in a string.
                            plaintext = srDecrypt.ReadToEnd();
                        }
                    }
                }

            }

            return plaintext;

        }
    }

3. 寄宿于IIS

CalculatorService.svc

<%@ ServiceHost  Service = "Services.CalculatorService"%>

服务类输出路径为bin\

4.服务端配置文件 Web.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="metadataBehavior">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="metadataBehavior" name="Services.CalculatorService">
        <endpoint binding="basicHttpBinding" contract="Contracts.ICalculator"></endpoint>        
      </service>
    </services>
  </system.serviceModel>
</configuration>

5 客户端调用类

    class Program
    {
        static void Main(string[] args)
        {
            //using (CalculatorServiceClient proxy = new CalculatorServiceClient())
            using (ChannelFactory<ICalculator> channelFactory = new ChannelFactory<ICalculator>("calculatorservice"))
            {
                ICalculator proxy = channelFactory.CreateChannel();
                using (proxy as IDisposable)
                {

                    DataTable dt = new DataTable("update");
                    dt.Columns.Add("aa", typeof(string));

                    DataRow dr = dt.NewRow();
                    dr["aa"] = 1;
                    dt.Rows.Add(dr);

                    DataSet ds = new DataSet("aab");
                    ds.Tables.Add(dt);

                    ds.GetXml();


                    using (AesCryptoServiceProvider myAes = new AesCryptoServiceProvider())
                    {
                        byte[] keyArray = UTF8Encoding.UTF8.GetBytes("0000000000000000");
                        byte[] ivArray = UTF8Encoding.UTF8.GetBytes("0000000000000000");

                        byte[] encrypted = EncryptStringToBytes_Aes(ds.GetXml(), keyArray, ivArray);

                        string aa = proxy.UpLoadData(encrypted);
                        Console.WriteLine(aa);
                    }
                }
            }
        }

        static byte[] EncryptStringToBytes_Aes(string plainText, byte[] Key, byte[] IV)
        {
            // Check arguments.
            if (plainText == null || plainText.Length <= 0)
                throw new ArgumentNullException("plainText");
            if (Key == null || Key.Length <= 0)
                throw new ArgumentNullException("Key");
            if (IV == null || IV.Length <= 0)
                throw new ArgumentNullException("Key");
            byte[] encrypted;
            // Create an AesCryptoServiceProvider object
            // with the specified key and IV.
            using (AesCryptoServiceProvider aesAlg = new AesCryptoServiceProvider())
            {
                aesAlg.Key = Key;
                aesAlg.IV = IV;

                // Create a decrytor to perform the stream transform.
                ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);

                // Create the streams used for encryption.
                using (MemoryStream msEncrypt = new MemoryStream())
                {
                    using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                    {
                        using (StreamWriter swEncrypt = new StreamWriter(csEncrypt))
                        {

                            //Write all data to the stream.
                            swEncrypt.Write(plainText);
                        }
                        encrypted = msEncrypt.ToArray();
                    }
                }
            }


            // Return the encrypted bytes from the memory stream.
            return encrypted;

        }

    }

6. 客户端配置文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <bindings />
    <client>
      <endpoint address="http://127.0.0.1/wcf/calculatorservice.svc"
        binding="basicHttpBinding" contract="Contracts.ICalculator"
        name="calculatorservice" />
    </client>
  </system.serviceModel>
</configuration>
