asp:Button ID="btnCancel" runat="server" Text="取消" onclick="btnCancel_Click" />

登錄驗(yàn)證功能
/// summary>
/// 用戶登錄
/// /summary>
/// param name="sender">/param>
/// param name="e">/param>
protected void btnLogin_Click(object sender, EventArgs e)
{
if (tbusername.Text == "")
{
Response.Write(@"script>alert('用戶名不能為空!');/script>");
}
if (tbpsw.Text == "")
{
Response.Write(@"script>alert('密碼不能為空!');/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('登錄成功!');/script>");
else
Response.Write(@"script>alert('登錄失??!');/script>");
}
}
}
注冊功能
/// summary>
/// 用戶注冊
/// /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('注冊成功!');/script>");
}
知識點(diǎn)歸納:
1.如何創(chuàng)建一個ASP.Net網(wǎng)站
2. 使用服務(wù)器控件實(shí)現(xiàn)界面設(shè)計(jì)
3. 對數(shù)據(jù)庫的簡單操作
一個簡單的用戶注冊、登錄就完成了,通過這個案例希望對大家的學(xué)習(xí)有所幫助。
