SilverLight 中的异步代码与 SharePoint

发布于 2025-01-08 14:41:46 字数 509 浏览 3 评论 0原文

我的代码有一些问题。我按下按钮后有 silverlight 按钮，我想加载文档库并获取有关该库中有多少项目的信息，我的代码是：

 var web = context.Web;
 List sharedDocumentsList = context.Web.Lists.GetByTitle("dokumenty");

 int i = sharedDocumentsList.ItemCount;

 context.Load(sharedDocumentsList);
 context.ExecuteQueryAsync(OnFileWriteSucceeded, OnFileWriteFailed);

但我仍然遇到同样的问题。

集合尚未初始化。尚未请求或请求尚未执行。可能需要明确请求

我如何获取 ItemCount。这只是一个简单的例子，我需要循环使用这个列表等等。但我需要解决这个主要问题。如何直接在按钮单击方法中使用此文档列表。

谢谢。

I have some problem with my code. I have silverlight button after I press button I want to load document library and get information about how many items are in this library co my code is:

 var web = context.Web;
 List sharedDocumentsList = context.Web.Lists.GetByTitle("dokumenty");

 int i = sharedDocumentsList.ItemCount;

 context.Load(sharedDocumentsList);
 context.ExecuteQueryAsync(OnFileWriteSucceeded, OnFileWriteFailed);

But I got still same problem.

The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explixitly requested

How Can I get ItemCount. This is only a simple example I need to work with this list in cycle and so on. But I need to solve this main problem. How to work with this documentlist directly in button click method.

Thank You.

这对我有用：

private List docList;
private void GetList()
{
    var context = new ClientContext(ApplicationContext.Current.Url);
    context.Load(context.Web);
    docList = context.Web.Lists.GetByTitle("dokumenty");
    context.Load(docList);
    context.ExecuteQueryAsync(GetListSucceded, GetListFailed);
}

private void GetListFailed(object sender, ClientRequestFailedEventArgs e)
{            
    Dispatcher.BeginInvoke(() => MyErrorFunction();
}

private void GetListSucceded(object sender, ClientRequestSucceededEventArgs e)
{
    Dispatcher.BeginInvoke(() => GetItemsCount());
}

private void GetItemsCount()
{
    MessageBox.Show(docList.ItemCount.ToString());
}

This works for me:

private List docList;
private void GetList()
{
    var context = new ClientContext(ApplicationContext.Current.Url);
    context.Load(context.Web);
    docList = context.Web.Lists.GetByTitle("dokumenty");
    context.Load(docList);
    context.ExecuteQueryAsync(GetListSucceded, GetListFailed);
}

private void GetListFailed(object sender, ClientRequestFailedEventArgs e)
{            
    Dispatcher.BeginInvoke(() => MyErrorFunction();
}

private void GetListSucceded(object sender, ClientRequestSucceededEventArgs e)
{
    Dispatcher.BeginInvoke(() => GetItemsCount());
}

private void GetItemsCount()
{
    MessageBox.Show(docList.ItemCount.ToString());
}
