默认页面Default.aspx
创建以上界面：
%@ Page Language="C#" AutoEventWireup="true" CodeFile="UserLogin.aspx.cs" Inherits="UserLogin" %> !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> html xmlns="http://www.w3.org/1999/xhtml"> head runat="server"> title>/title> /head> body> div align="center"> h1>用户登录页面/h1> form id="form1" runat="server"> p> asp:Label ID="lbusername" runat="server">用户名：/asp:Label> asp:TextBox ID="tbusername" runat="server">/asp:TextBox> /p> p> asp:Label ID="lbpsw" runat="server">密 码：/asp:Label> asp:TextBox ID="tbpsw" runat="server" TextMode="Password">/asp:TextBox> /p> p>asp:Button ID="btnLogin" runat="server" Text="登录" onclick="btnLogin_Click" /> asp:Button ID="btnCancel" runat="server" Text="取消" onclick="btnCancel_Click" /> /p> /form> /div> /body> /html>
登录验证功能
/// summary>
/// 用户登录
/// /summary>
/// param name="sender">/param>
/// param name="e">/param>
protected void btnLogin_Click(object sender, EventArgs e)
{
if (tbusername.Text == "")
{
Response.Write(@"script>alert('用户名不能为空！');/script>");
}
if (tbpsw.Text == "")
{
Response.Write(@"script>alert('密码不能为空！');/script>");
}
string username = tbusername.Text;
string password = tbpsw.Text;
string sql = "select * from T_user where username=@username and password=@password";
SqlParameter[] parameters = { new SqlParameter("@username",username), new SqlParameter("@password", password) };
using (SqlConnection conn = new SqlConnection(connstr))
{
conn.Open();
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = sql;
cmd.Parameters.AddRange(parameters);
DataSet ds = new DataSet();
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
adapter.Fill(ds);
DataTable table = ds.Tables[0];
if(table != null)
Response.Write(@"script>alert('登录成功！');/script>");
else
Response.Write(@"script>alert('登录失败！');/script>");
}
}
}
注册功能
/// summary>
/// 用户注册
/// /summary>
/// param name="sender">/param>
/// param name="e">/param>
protected void brnRegister_Click(object sender, EventArgs e)
{
string username = tbusername.Text;
string password = tbpsw.Text;
string sql = "Insert into T_user(username, password) values(@username,@password)";
SqlParameter[] parameters = { new SqlParameter("@username", username), new SqlParameter("@password", password) };
using (SqlConnection conn = new SqlConnection(connstr))
{
conn.Open();
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = sql;
cmd.Parameters.AddRange(parameters);
cmd.ExecuteNonQuery();
}
}
Response.Write(@"script>alert('注册成功！');/script>");
}
知识点归纳：
1.如何创建一个ASP.Net网站
2. 使用服务器控件实现界面设计
3. 对数据库的简单操作
一个简单的用户注册、登录就完成了，通过这个案例希望对大家的学习有所帮助。
