c# 后台如何修改已有html控件,c# – 如何在后面的代码中访问html控件

我试图按照这个

example来验证凭据.但是,它为登录表单使用asp：controls.

如果我使用html控件,可以应用CSS样式,例如

Login

Sign in to your account.

Forgot your password?

如何访问用户名和密码在代码背后类似？

protected void LoginButton_Click(object sender, EventArgs e)

{

// Validate the user against the Membership framework user store

if (Membership.ValidateUser(UserName.Text, Password.Text))

{

// Log the user into the site

FormsAuthentication.RedirectFromLoginPage(UserName.Text, RememberMe.Checked);

}

// If we reach here, the user's credentials were invalid

InvalidCredentialsMessage.Visible = true;

}

什么是正确的语法,而不是UserName.Text,Password.Text？
