C# Socket登录验证示例

C# Socket登录验证

一、说明


本程序只是学习应用Socket登录验证和序列化、反序列化的应用，所以只使用了最基本Socket函数，不是框架。


为了便于学习，服务端使用Access数据库，如需修改数据库内的图片，自建程序文件，写代码：


for (int i=0;i<29;i )


{


  byte[] imagebytes = ReadImageFile(i “.jpg”);


  OleDbCommand com = new OleDbCommand(“UPDATE UserInfo SET User_Portrait=(@ImageList) WHERE id=” (i 1), Conn);


  com.Parameters.Add(“ImageList”, OleDbType.Binary);


  com.Parameters[“ImageList”].Value = imagebytes;


  com.ExecuteNonQuery();


 }


将图片更新到数据库中，本程序中限定图像大小为80*80。


数据结构定义在dataStructure.cs，每条传输数据生成新的验证码，根据验证解密，见每个class中的SecretKey。


总的密钥：


string sKey = “㊣o(╥﹏╥)o”; // 密钥8位


服务端客户端要一致。

二、使用

Client客户端设置服务器地址，可以是本机，Login_Form.cs。


private string ServerAddress = “服务器ip”; // 服务器ip地址


public static int port = 51888; // 使用的端口号


Server服务端与客户端一致，Form1.cs。


private IPAddress[] ServerAddress = Dns.GetHostAddresses(“服务器ip”); // 服务器ip地址


private int port = 51888; // 使用的端口号


编译后先执行Server.exe，再执行Client.exe，


用户名1000至1028，密码为123456

三、使用的组件和修改


界面使用：http://www.haolizi.net/example/view_14426.html 的SQK.DLL


修改了UiScrollBoxMethod.cs，增加了滚动到最底部函数，自行编写：


SetBottom()函数


……


foreach (UiControlsMethod.ADraggableGDIObject item in m_DraggableGDIObjects)


{


   set_y = limtY;


    ……


   item.Region = new Rectangle(0, set_y, item.Region.Width, item.Region.Height);


   ScrollBox_.Invalidate();


}


修改了UiInputBoxMethods.cs，解决了粘贴带文字样式的问题，本程序中没有使用，可以参照本程序INputForm.cs自行修改。

四、Win7、Win8都可运行，建议Win10运行，效果更好，Vs2017编译，2015也可以。


.Net4.6.1，如其他版本，需重新编译http://www.haolizi.net/example/view_14426.html 的SQK.DLL
