Microsoft.Office.Interop.Outlook错误 - 文件filename.ics不是有效的Internet日历文件

时间：2012-11-08 23:05:16

标签： c# outlook interop visual-studio-2012

我正在尝试在Web应用上使用Outlook 2010日历的内容。为此，我在IIS 7.5 / Windows 2008 R2计算机上设置了启用WebDAV的网站。从Outlook 2010开始，我将日历发布到我设置的网站，这导致网站文件夹中出现了一个新的.ics文件。

现在，为了读取/解析文件的内容，我将该文件复制到我的VS 2012计算机上，该计算机与安装Outlook的计算机相同。我使用此示例来解析文件：http://msdn.microsoft.com/en-us/library/office/bb644609%28v=office.12%29.aspx

当我在示例中使用此代码（稍微修改一下）时，我得到2个异常，一个在OpenSharedItem上，表示Operation Failed，另一个在OpenSharedFolder上，后者表示该文件不是有效的Internet日历文件。 / p> 

string fileName = "filename.ics";

if (!File.Exists(fileName))
    Console.WriteLine("File Does NOT Exist");
else
    Console.WriteLine("File Exists");

// First try to open the icalendar file as an appointment 
// (not a calendar folder).
object item = null;
try
{
    Application a = new Application();

    item = a.Session.OpenSharedItem(fileName);
    Console.WriteLine("open shared item");
}
catch(System.Exception e)//gets thrown
{
    Console.WriteLine("Open shared item failed");
    Console.WriteLine(e.Message + e.StackTrace);
}

if (item != null)
{
    Console.WriteLine("item not null");

    // Display the item
    OutlookItem olItem = new OutlookItem(item);
    olItem.Display();
    return;
}

// If unsucessful in opening it as an item, 
// try opening it as a folder
Outlook.Folder importedFolder = null;
try
{
    Application a = new Application();              
    importedFolder = a.Session.OpenSharedFolder(fileName, Type.Missing, Type.Missing, Type.Missing) as Outlook.Folder;
    Console.WriteLine("open shared folder");
}
catch (System.Exception e)//gets thrown
{
    Console.WriteLine("Open shared folder failed");
    Console.WriteLine(e.Message + e.StackTrace);
}

// If sucessful, open the folder in a new explorer window
if (importedFolder != null)
{
    //never reached
}

2 个答案:

答案 0 :(得分：1)

您可以尝试文件的完整路径吗？

示例：

string fileName = "c:\temp\filename.ics";

编辑：

阅读OpenSharedItem我发现：

  

此方法不支持 iCalendar日历（.ics）文件。打开   iCalendar日历文件，可以使用OpenSharedFolder方法   NameSpace对象。

但在opensharedfolder我发现：

  

此方法不支持 iCalendar约会（.ics）文件。至   打开iCalendar约会文件，即可使用OpenSharedItem   NameSpace对象的方法。

所以，我们的第一个问题是：这是iCalendar日历还是iCalendar约会？回答这个问题我们知道是否需要使用OpenSharedItem或OpenSharedFolder。

答案 1 :(得分：1)

OpenSharedItem仅适用于具有一个VEVENT的ICS文件。如果ICS文件包含一个VEVENT而其他VEVENTS是第一个VEVENT的例外，则将标题X-MS-OLK-FORCEINSPECTOROPEN：TRUE添加到ICS文件中，例如：

BEGIN:VCALENDAR
VERSION:2.0
X-MS-OLK-FORCEINSPECTOROPEN:TRUE

现在，OpenSharedItem将毫无问题地加载ics文件。
