DispatcherTimer.Start（）'必须声明一个主体，因为它在MVC4中没有标记为abstract，extern或partial [英] DispatcherTimer.Start()' must declare a body because it is not marked abstract, extern, or partial in MVC4

问题描述

public void DispatcherTimerSetup(HttpClient httpClient)
       {
           Client = httpClient;
           dispatcherTimer = new DispatcherTimer();
           dispatcherTimer.Tick += dispatcherTimer_Tick;
           dispatcherTimer.Interval = new TimeSpan(0, 1, 0); // TimeSpan for 1 Minute 0 secs
           if (!dispatcherTimer.IsEnabled)
           {
               dispatcherTimer.Start();
           }
       }

class DispatcherTimer
   {
       public void Start();
   }

这里我收到此错误



DispatcherTimer.Start（）'必须声明一个正文，因为它没有标记为abstract，extern或partial

here I am getting this ERROR

DispatcherTimer.Start()' must declare a body because it is not marked abstract, extern, or partial

推荐答案

在你的 DispatcherTimer 类，你声明一个 Start（）方法，但你没有给它一个正文（即：你没有实现方法）。您应该：

In your DispatcherTimer class, you declare a Start() method but you do not give it a body (i.e.: you do not implement the method). You should have:

class DispatcherTimer
{
   public void Start()
   {
      // Your implementation of the Start() method
   }
}

或者将类创建为抽象，将方法创建为虚拟：

or create the class as abstract and the method as virtual:

abstract class DispatcherTimer
{
   public virtual void Start();
}

首先我们需要使用System.Windows.Threading添加此NameSpace

;



之后我们需要添加Windowsbase.dll程序集

现在我的解决方案工作正常



感谢所有

First we need to add this NameSpace
using System.Windows.Threading;

After that we need to add Windowsbase.dll Assembly
Now My solution working fine

Thanks to all
