【檔案】-->【建立】-->【網站】-->【ASP.Net網站】--【完成】
預設頁面Default.aspx
建立以上介面：
<%@ 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>使用者登入頁面</h1> <form id="form1" runat="server"> <p> <asp:Label ID="lbusername" runat="server">使用者名稱：</asp:Label> <asp:TextBox ID="tbusername" runat="server"></asp:TextBox> </p> <p> <asp:Label ID="lbpsw" runat="server">密 碼：</asp:Label> <asp:TextBox ID="tbpsw" runat="server" TextMode="Password"></asp:TextBox> </p> <p><asp:Button ID="btnLogin" runat="server" Text="登入" onclick="btnLogin_Click" /> <asp:Button ID="btnCancel" runat="server" Text="取消" onclick="btnCancel_Click" /> </p> </form> </div> </body> </html>
登入驗證功能
/// <summary> /// 使用者登入 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void btnLogin_Click(object sender, EventArgs e) { if (tbusername.Text == "") { Response.Write(@"<script>alert('使用者名稱不可為空！');</script>"); } if (tbpsw.Text == "") { Response.Write(@"<script>alert('密碼不可為空！');</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('登入成功！');</script>"); else Response.Write(@"<script>alert('登入失敗！');</script>"); } } }
註冊功能
/// <summary> /// 使用者註冊 /// </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('註冊成功！');</script>"); }
知識點歸納：
1.如何建立一個ASP.Net網站
2. 使用伺服器控制項實現介面設計
3. 對資料庫的簡單操作
一個簡單的使用者註冊、登入就完成了，通過這個案例希望對大家的學習有所協助。
