C# 名称为；"；在这种情况下不存在。

我一直在看其他文章试图解决这个问题，但我对在InfoPath中编码真的很陌生。我有一个允许我使用Infopath在SharePoint列表中提取项目的代码。我不断得到一个错误，即“名称“e”在当前上下文中不存在”。请帮忙

假设单击的

是一个带有
void（string，XPathNavigator）
签名的事件，您应该这样添加事件处理程序：

public void InternalStartup()
{
    ((ButtonEvent)EventManager.ControlEvents["UpdateList"]).Clicked += UpdateList_Clicked;
}

你是说

public void InternalStartup()
{
    ((ButtonEvent)EventManager.ControlEvents["UpdateList"]).Clicked +=
      (s, e) => UpdateList_Clicked("Update", e.Source.CreateNavigator());
}

您的InternalStartup方法中是否存在错误？它看起来没有定义
