我添加了这个事件接收器（基于我在这里找到的）：

using System;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Security;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.Workflow;

namespace PostTravelWizard.PostTravelItemEventReceiver
{
    /// <summary>
    /// List Item Events
    /// </summary>
    public class PostTravelItemEventReceiver : SPItemEventReceiver
    {
       /// <summary>
       /// An item was added.
       /// </summary>
       public override void ItemAdded(SPItemEventProperties properties)
       {
           base.ItemAdded(properties);
           //GeneratePDF(); <= "The name 'GeneratePDF' does not exist in the current context
       }

       /// <summary>
       /// The list received a context event.
       /// </summary>
       public override void ContextEvent(SPItemEventProperties properties)
       {
           base.ContextEvent(properties);
           // TODO: What "context event" occurs here? To what event should I respond?
       }

    }
}

我希望，当更新列表（从客户端/Javascript）时，然后在代码隐藏中检索这些值以生成 PDF 文件。我的 *.ascx.cs 文件中有这段代码：

public partial class PostTravelWizardWebPartUserControl : UserControl
{
    . . .

    public void GeneratePDF(PostTravelData ptd)
    {
        ;//bla
    }

...但它不让我GeneratePDF()从事件接收器调用 - 它失败了

当前上下文中不存在名称“GeneratePDF”

为什么？我该如何纠正这个问题？

GeneratePDF是PostTravelWizardWebPartUserControl类的实例方法。为了从你那里调用它，PostTravelItemEventReceiver你必须创建一个实例PostTravelWizardWebPartUserControl或者让method( GeneratePDF)成为static。

情况1

public override void ItemAdded(SPItemEventProperties properties)
{
    base.ItemAdded(properties);
    new PostTravelWizardWebPartUserControl().GeneratePDF();
}

案例2

public partial class PostTravelWizardWebPartUserControl : UserControl
{
    public static void GeneratePDF(PostTravelData ptd)
    {
        ;//bla
    }
}


public class PostTravelItemEventReceiver : SPItemEventReceiver
{
    base.ItemAdded(properties);
    PostTravelWizardWebPartUserControl.GeneratePDF();
}
