错误，当前上下文中不存在名称“True”
是有关RequiredFieldValitor控件的使用的，刚自学的，想不出怎么解决，各位帮帮忙拉<%@ Page Language="C#" %>
<script language="C#" runat="server"></script>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.
<script runat="server">
protected void ValidateBtn_Click(object sender, EventArgs e)
{
if(Page.IsValid ==True)
{
Response.Write("ID:"+yourID.Text+" Email:"+yourEmail.Text );
}
}
</script>
<html xmlns="http://www. >
