1 完成登录页面（到记事本文件进行密码和用户名的验证）。

ASP中的代码:


<form id="form1" runat="server">
<div>

<table align="center" border="1px" width="50%">

<tr><td class="style1" align="center"> 用户名:</td> <td><input type="text" id="userName" runat="server" /></td></tr>
<tr><td class="style1" align="center">密码:</td> <td><input type="password" id="passwordTxt" runat="server" /></td></tr>
<tr><td class="style1" align="center"><input style="width:79px;" type="button" id="btn_login" value="登录" Xonserverclick="Button1_Click" runat="server" /></td>
<td align="center"> <label id="htmlText" runat="server"></label></td></tr>



</table>

</div>
</form>



方法中的代码:

protected void Button1_Click(object sender, EventArgs e)
{
string[] lines = File.ReadAllLines("password.txt");
string username=userName.Value;
string password=passwordTxt.Value;
for(int i=0;i<lines.Length;i++)
{
string[] line = lines[i].Split(' ');
if (line[0] == username && line[1] == password)
{
htmlText.InnerText = "登录成功!";
return;
}
else
{
htmlText.InnerText = "登录失败!";
}
}

}

2 完成 用户注册页面（将注册信息显示在本页面 div 中）。

ASP网页中的代码:

<form id="form1" runat="server">
<div>

<table align="center" border="1px" width="50%">

<tr><td class="style1" align="center"> 用户名:</td> <td><input type="text" id="userName" runat="server" /></td></tr>
<tr><td class="style1" align="center">密码:</td> <td><input type="password" id="passwordTxt" runat="server" Xonclick="return passwordTxt_onclick()" /></td></tr>

<tr><td class="style1" align="center">确认密码:</td> <td><input type="password" id="passwordTxt1" runat="server" Xonclick="return passwordTxt_onclick()"/> <label id="label1" runat="server"></label> </td></tr>
<tr><td> 性别:</td> <td><input type="radio" id="radio1" runat="server" name="sex" />男 <input type="radio" id="radio2" name="sex" name="sex"/>女</td> </tr>
<tr><td>头像:</td> <td><input type="file" id="file1" runat="server" /> </td></tr>

<tr><td class="style1" align="center"><input style="width:79px;" type="button" id="btn_login" value="登录" Xonserverclick=" Button1_Click" runat="server" /></td>
<td align="center"> <label id="htmlText" runat="server"></label></td></tr>

</table>

<div id="divResult" runat="server"></div>

</div>
</form>

方法中的代码:

protected void Button1_Click(object sender, EventArgs e)
{

StringBuilder sb = new StringBuilder();
sb.Append("用户名:");
sb.Append(userName.Value);
sb.Append("<br/>");

sb.Append("密码:");
sb.Append(passwordTxt.Value);
sb.Append("<br/>");

if (passwordTxt.Value.Trim() == passwordTxt1.Value.Trim())
{
sb.Append("确认密码:");
sb.Append(passwordTxt1.Value);
sb.Append("<br/>");
}
else
{
label1.InnerText = "两次密码不一致!!!";
passwordTxt.Value = "";
passwordTxt1.Value = "";

sb.Append("性别：");
if (radio1.Checked == true)
{
sb.Append("男");
}
else
{
sb.Append("女");
}
sb.Append("<br/>");


sb.Append("头像");

string filename = file1.PostedFile.FileName;
filename = DateTime.Now.Ticks.ToString() + filename.Substring(filename.LastIndexOf("."));
this.file1.PostedFile.SaveAs(Server.MapPath("upLoad"+"\\"+filename));
