为什么要“线程化"?是Visual Studio未知的吗? [英] Why "threading" is unknown for visual studio?

问题描述

我包含了using System.Windows;，但是线程仍然在命名空间中不存在 ?！

I include using System.Windows; but threading still it doesn't exist in the namespace ?!

            using System;
        using System.Collections.Generic;
        using System.Linq;
        using System.Web;
        using System.Web.UI;
        using System.Web.UI.WebControls;
        using System.Data.SqlClient;
        using System.Configuration;
        using System.Data;
        using System.Net.Mail;
        using System.Net;
        using System.ComponentModel;
        using System.Drawing;
        using System.Text;
        using System.Windows;
        using System.Timers;
        using Graduation_Project;




        namespace GP
        {
            public partial class Register : System.Web.UI.Page
            {
                static int count = 0;
                static int timer = 600;
                protected void Page_Load(object sender, EventArgs e)
                {

                    System.Windows.Threading.DispatcherTimer dt = new System.Windows.Threading.DispatcherTimer();
                    dt.Interval = new TimeSpan(0, 0, 0, 0, 600000); // 600000 Milliseconds
                    dt.Tick += new EventHandler(dt_Tick); 

                }

推荐答案

System.Windows.Threading.DispatcherTimer在WindowsBase.dll程序集中.确保您已添加对该程序集的引用.

System.Windows.Threading.DispatcherTimer is in WindowsBase.dll assembly. Make sure you have added reference to that assembly.

MSDN -

更新-

DispatcherTimer用于WPF and Silverlight apps.它不能用于asp.net项目.相反，您应该使用计时器类用于Web项目.

DispatcherTimer is meant for WPF and Silverlight apps. It can't be used for asp.net project. Instead you should use Timer class meant for web projects.
