Web.config 文件中包含验证信息

 1.Login.cs部分

   protected void btnSubmit_Click(object sender, EventArgs e)    {        if (FormsAuthentication.Authenticate(txtUsername.Text, txtPassword.Text))        {            FormsAuthentication.RedirectFromLoginPage(txtUsername.Text, true);

        }

        else        {            Response.Write("error");        }    }

2.web.config中

<system.web>  <authentication mode="Forms">   <forms name="222" loginUrl="Login.aspx" path="/">   <!--此处name,password 的格式必须与passwordFormat格式一致，不然前面的识别不了-->    <credentials passwordFormat="Clear">     <user name="123" password="123"/>    </credentials>   </forms>  </authentication>  <authorization>            <deny users="?"/>  </authorization>

</system.web>

3.得到存储在web.config中的加密值

 string str = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Text, "Sha1");
