Question

为什么我没引用“System.Web.UI;”

//using System.Web;
//using System.Web.UI;

using System;

//using System.Web;
//using System.Web.UI;

using System;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
this.text1.Text = "xxxx";
this.text2.Text = "xxxx";
}
}

public void link(object sender, EventArgs e)
{
Response.Write(this.text1.Text + this.text2.Text);
}

}
为什么我没引用“System.Web.UI;”
public partial class _Default : System.Web.UI.Page 这里仍旧可以定义？

System.Web.HttpContext.Current.Request.UserHostAddress 补充,如果当前项目未引用System.Web,那么需要手动添加,方法: 在vs.net,右边的“解决方案资源管理
