使用 SearchFilterCollection 按电子邮件地址搜索 Exchange 邮箱

Question

我正在使用 Exchange Web 服务搜索电子邮件收件箱（在 Exchange 2010 上）。

在我的 SearchFilterCollection 中，我想包含电子邮件的 From.Address 属性，因为我只想检索包含特定域（例如 @domain.co.uk）的电子邮件

这是我的代码：

SearchFilter.SearchFilterCollection searchFilterCollection = new SearchFilter.SearchFilterCollection(LogicalOperator.And);
searchFilterCollection.Add(new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));
searchFilterCollection.Add(new SearchFilter.IsEqualTo(EmailMessageSchema.HasAttachments, true));

// **** PROBLEM HERE ON BELOW LINE****       
searchFilterCollection.Add(new SearchFilter.ContainsSubstring(EmailMessageSchema.From, "@domain.co.uk")); // 

// add the exceptions
for (int iEx = 0; iEx < e2c.emailExceptions.Count; iEx++)
    {
    searchFilterCollection.Add(new SearchFilter.Not(new SearchFilter.ContainsSubstring(EmailMessageSchema.Subject, e2c.emailExceptions[iEx])));
    }

    ItemView view = new ItemView(100);
    view.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Ascending);

    // Find the first email message in the Inbox that has attachments. This results in a FindItem operation call to EWS.
    FindItemsResults<Item> results = service.FindItems(WellKnownFolderName.Inbox, searchFilterCollection, view);

有没有在 SearchFilter 中包含电子邮件地址的好方法？

Answer 1

前几天我刚刚创建了一个搜索文件夹，使用来自How to: Work with search folders by using EWS in Exchange 主题的示例：

// Create a search filter to express the criteria
// for the folder.
EmailAddress manager = new EmailAddress("sadie@contoso.com");

SearchFilter.IsEqualTo fromManagerFilter =
    new SearchFilter.IsEqualTo(EmailMessageSchema.Sender, manager);

现在这是使用 Sender 属性，而不是 From 属性。我认为您可以简单地将一个替换为另一个，但我没有测试确定。
