Question

我想从一个列表项（在ItemCreated事件中）读取另一个新ListItem的附件。如何使用客户端对象模型执行此操作？我发现的只是服务器端代码......

另一个问题：删除列表项时是否还删除了附件，或者它们是否仍存在于服务器上？

我明白了！以下代码对我有用：

IRibbonControl controlThatFiredEvent = e.Control; 
object context = controlThatFiredEvent.Context; 

if (context == null) return; 
if (context is Outlook.Explorer) 
{ 
    Outlook.Explorer explorer = context as Outlook.Explorer; 
    Outlook.Selection selection = null; 
    try 
    { 
        selection = explorer.Selection; 
    } 
    catch (Exception ex) 
    { 
    } 
    if (selection != null) 
    { 
        if (selection.Count > 0) 
        { 
            object item = selection[1]; 
            if (item is Outlook.ContactItem) 
            { 
                Outlook.ContactItem contact1 = item as Outlook.ContactItem; 
                // process contact  
                MessageBox.Show("ContactCallMenu_OnCreate - contact1: " + contact1.Subject); 
            } 
            Marshal.ReleaseComObject(item); item = null; 
        } 
        Marshal.ReleaseComObject(selection); selection = null; 
    }  
} 
else if (context is Outlook.Inspector) 
{ 
    Outlook.Inspector inspector = context as Outlook.Inspector; 
    object item = inspector.CurrentItem; 
    if (item is Outlook.ContactItem) 
    { 
        Outlook.ContactItem contact2 = item as Outlook.ContactItem; 
        // process contact  
        MessageBox.Show("ContactCallMenu_OnCreate - contact2: " + contact2.Subject); 
    } 
    Marshal.ReleaseComObject(item); item = null;  
}

它将一个列表项（fromItem）的附件复制到新项目！
