Dispatcher.Invoke((ThreadStart ... [英] Dispatcher.Invoke((ThreadStart...

问题描述

大家好，

我已经在项目中为ICollection f实现了Extension方法，从根本上来说，我正在尝试对ApplicationIdle状态执行一些与Datagrid相关的操作.这是代码.

Hi all,

i have implemented a Extension method for ICollection f in project that bacically i am trying to do some datagrid related operation on ApplicationIdle state. here is the code.

public static class CollectionExtension
   {
       /// <summary>
       /// Set item Binding to the DataGrid
       /// </summary>
       /// <typeparam name="T">Source type</typeparam>
       /// <param name="Collection"> Collection </param>
       public static void SetItemBinding<T>(this ICollection<T> Collection, DataGrid DataGrid)
       {
           Dispatcher.Invoke((ThreadStart)delegate()
           {
               .....

           }, DispatcherPriority.ApplicationIdle, null);
       }
   }

但是在代码 Dispatcher.Invoke (((ThreadStart)delegate()
说
错误:
非静态字段，方法或属性需要对象引用.我做错了什么问题.

But am getting a error in this part of code Dispatcher.Invoke((ThreadStart)delegate()
saying that
Error:
An object reference is required for the non-static field,method or Property. what aould be the issue where am i doing wrong.

推荐答案

我使用了Dispatcher，但它似乎不是很可靠.有了更多的任务运气:首先从UI线程上的某个位置获取TaskScheduler:

I have used the Dispatcher, and it does not seem to be very reliable. Had much more luck with tasks: First get a TaskScheduler from somewhere that is on the UI thread:

TaskScheduler uiScheduler = TaskScheduler.FromCurrentSynchronizationContext();

然后在需要进行更改的地方使用任务:

Then in the place you need to make changes use a task:

Task task = Task.Factory.StartNew(() =>
    {
       //Your code here
    }, CancellationToken.None, TaskCreationOptions.None, uiScheduler);

希望对您有所帮助.

Hope it helps.
