我正在使用 Exchange Server 2007 SP3

，并且我能够使用以下代码连接 Exchange Web 服务

ExchangeServiceBinding esb = new ExchangeServiceBinding();
esb.RequestServerVersionValue = new RequestServerVersion();
esb.RequestServerVersionValue.Version = ExchangeVersionType.Exchange2007_SP1;
esb.Credentials = new NetworkCredential("<user_id>", "<password>", "<domain>");
esb.Url = @"https://<server_fqdn>/ews/Exchange.asmx";

我正在寻找下载未读附件的代码。

请你帮助我好吗？

我发现了这一点：

private static void ProcessItems(ExchangeService exchangeService)
{
    var offset = 0;
    const int pageSize = 100;

    FindItemsResults<Item> result;

    do
    {
        var view = new ItemView(pageSize, offset)
        {
            SearchFilter = new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false)
        };

        result = exchangeService.FindItems(WellKnownFolderName.Inbox, view);

        foreach (var item in result)
        {
            ProcessItem(item);
        }

        offset += pageSize;
    } while (result.MoreAvailable);
}

然后从方法 ProcessItem 你可以做任何你想做的事情，比如下载附件等等......

I have found this:

private static void ProcessItems(ExchangeService exchangeService)
{
    var offset = 0;
    const int pageSize = 100;

    FindItemsResults<Item> result;

    do
    {
        var view = new ItemView(pageSize, offset)
        {
            SearchFilter = new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false)
        };

        result = exchangeService.FindItems(WellKnownFolderName.Inbox, view);

        foreach (var item in result)
        {
            ProcessItem(item);
        }

        offset += pageSize;
    } while (result.MoreAvailable);
}

then from the method ProcessItem you do whatever you want to do like download attachments and so on...
