带事件处理程序的静态函数 [英] Static function with event handler

问题描述

当我在Windows Phone 8中使用  OpenReadCompleted事件创建静态功能时，我收到以下错误。

错误16非静态字段，方法或属性'Demo_Dev.Mainport.downloadclient_OpenReadCompleted（object，System.Net.OpenReadCompletedEventArgs）'
  
 
这是我的代码：
 public static void downloadfile（）
 {
 if（App。 downdetails.Count！= 0）
 {
 App.change = true; 
 var downloadclient = new WebClient（）; 
 downloadclient.OpenReadAsync（new Uri（"my url here"））; 
 downloadclient.OpenReadCompleted + =  downloadclient_OpenReadCompleted ; 
} 
} 
我在带下划线的区域收到了该错误。
 
 
如何解决此问题？ 
 
 
 
解决方案
 
 
您的"downloadclient_OpenReadCompleted"是什么？函数看起来像？
 
 
你不需要发布完整的函数，只需要发布定义，类型和参数。
 
 
 
 
 
 
Hi,
when i'm creating a static function with OpenReadCompleted event in windows phone 8, i received the below error.
Error	16	An object reference is required for the non-static field, method, or property 'Demo_Dev.Mainport.downloadclient_OpenReadCompleted(object, System.Net.OpenReadCompletedEventArgs)'
Here is my code :
public static void downloadfile()
        {
            if (App.downdetails.Count!=0)
            {
                   App.change =true;
                   var downloadclient = new WebClient();
                   downloadclient.OpenReadAsync(new Uri("my url here"));
                   downloadclient.OpenReadCompleted +=downloadclient_OpenReadCompleted;
            }
        }
i received that error on the underlined area.
How to resolve this issue?
解决方案
What does your "downloadclient_OpenReadCompleted" function look like?
You don't need to post the full function, just the definition, type, and arguments.
