1.login.aspx

Copy Code code as follows:

<form id= "Form1" runat= "Server" method= "POST" >
<div>
<div>
<asp:label id= "Lbluser" runat= "server" text= "username" ></asp:Label>
<asp:textbox id= "Txtuser" runat= "Server" ></asp:TextBox>
</div>
<div></div>
<div>
<asp:label id= "lblpwd" runat= "server" text= "password" ></asp:Label>
<asp:textbox id= "txtpwd" runat= "Server" ></asp:TextBox>
</div>
<div>
<asp:button id= "Button1" runat= "server" text= "login" onclick= "button1_click" style= "width:40px"/>
</div>
</div>
</form>

Login.aspx.cs

Copy Code code as follows:

protected void Button1_Click (object sender, EventArgs e)
{
String user = Request.Form.Get ("Txtuser"). ToString ()//The client sends the server a user name to submit
string pwd = Request.Form.Get ("Txtpwd"). ToString (); The password the client sends the server to submit
if (user = = "1" && pwd = = "1")
{
Response.Redirect ("main.aspx?user=" + user); Jump to Main Page
}
Else
{
Response.Write ("Login Failed");
}

2.main.aspx.cs

Copy Code code as follows:

protected void Page_Load (object sender, EventArgs e)
{
String user = request.querystring["user"]. ToString ();//Get user username
Response.Write ("Welcome" + user + "login");
}

When the login page gets the correct username and password, the password jumps to the main page, and the home page prompts you for a successful login. When you enter an error, you will be prompted for a login failure.
