第一步：首先新建一个页面register页面，在该页面的前台添加上用户名、密码、邮箱地址和三个文本框以及注册按钮。
第二步：在register页面的register.aspx.cs页面加上以下代码：
public void sendMail(string email, string activeCode,int number)
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress("q******09@126.com");////填写一个126的邮箱
msg.To.Add(email);
msg.Subject = "请激活注册";
StringBuilder contentBuilder = new StringBuilder();
contentBuilder.Append("请单击以下连接完成激活！");
contentBuilder.Append("<a href='http://localhost:8899/CheckActiveCode.aspx?activecode="+activeCode+"&id="+number+"'>激活</a>");
msg.Body = contentBuilder.ToString();
msg.IsBodyHtml = true;
SmtpClient client = new SmtpClient();
client.Host = "smtp.126.com";//发件方服务器地址
client.Port = 25;//发件方端口
NetworkCredential credetial = new NetworkCredential();
credetial.UserName = "qzc900809";
credetial.Password = "900809";
client.Credentials = credetial;//把证书交给代理。
client.Send(msg);/////发送邮件
}
第三步：在注册按钮的单击事件中加上以下代码：
protected void Button1_Click(object sender, EventArgs e)
{
string userName = this.TextBox1.Text;
string password = this.TextBox2.Text;
string email = this.TextBox3.Text;
string activeCode = Guid.NewGuid().ToString().Substring(0, 8);//生成激活码
string conStr = ConfigurationManager.ConnectionStrings["conStr"].ConnectionString;//在web.Confing中设置连接数据库字符串
int number;
using (SqlConnection con = new SqlConnection(conStr))
{
string sql = "insert into email (UserName,Password,Email,Active,ActiveCode) values(@username,@password,@email,@active,@activecode)";
SqlParameter[] prams = new SqlParameter[] {
new SqlParameter("@username",userName),
new SqlParameter("@password",password),
new SqlParameter("@email",email),
new SqlParameter("@active",false),/////////这个是查看是否激活
new SqlParameter("@activecode",activeCode)///////激活码
};
using (SqlCommand cmd = new SqlCommand(sql, con))
{
con.Open();
cmd.Parameters.AddRange(prams);
number = cmd.ExecuteNonQuery();
}
}
if (number > 0)
{
sendMail(email, activeCode);
//sendMail(string email,string activeCode,int id);//给注册用户发邮件
Response.Redirect("regionMessage.aspx");///////这个可有可无，只是一个提示成功的页面
}
else
{
Response.Write("注册失败，请重新注册！");
}
}
第四步：再重新新建一个CheckActiveCode.aspx页面，然后再该页面（CheckActiveCode.aspx.cs）的Page_Load中
加上以下代码：
//1取出参数id
int id = Convert.ToInt32(Request["zcid"]);
string activeCode = Request["activecode"].ToString();
//2判断id为id的记录是否存在。
//连接数据库
string conStr = ConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
int number;
using (SqlConnection con = new SqlConnection(conStr))
{
string sql = "select count(*) from Registor where
zcid=@id";
using (SqlCommand cmd=new SqlCommand(sql,con))
{
con.Open();
cmd.Parameters.AddWithValue("@id",id);
number=Convert.ToInt32(cmd.ExecuteScalar());
}
}
if (number > 0)
{
//如果该用户存在取出其ActiveCode字段进行比较。如果一样。把Ative字段修改为true
&nbs
有时候会遇到这样的需求，不希望命令行的某些参数被ps出来，比如命令行参数里可能存在一些用户名和密码之类的东西，在linux下如果你想隐藏这些东西的话，可以直接将argv中的这些参数变成其他东西，比如xxxxx，下面是一个hideArg函数示例
void hideArg(int argc, char** argv, const char* arg)
{
for (int i = 1; i < argc; i++)
{
if (strcmp(argv[i], arg) || i == (argc - 1))
{
continue;
}
i++;
int j = strlen(argv[i]);
for (j = j - 1; j >= 0; j--)
{
argv[i][j] = 'x';
}
}
}
