使用EWS c#向组发送电子邮件

本文关键字：电子邮件 EWS 使用 | 更新日期: 2023-09-27 18:04:24

我正在使用ExchangeWebServices c#。
我在给分发名单发邮件，所以我创建了一个组，如下所示:

private void CreateGroup(ExchangeService service)
{
    // Create a new contact group object.
    ContactGroup myContactGroup = new ContactGroup(service);
    // Give the group a name.
    myContactGroup.DisplayName = "TestContactGroup";
    // Add some members to the group.
    myContactGroup.Members.Add(new GroupMember("Euser@mydomain.com"));
    myContactGroup.Members.Add(new GroupMember("Euser1@mydomain.com"));
    myContactGroup.Members.Add(new GroupMember("Euser2@mydomain.com"));
    // Save the group.
    myContactGroup.Save();
}

现在我想给这个组发邮件，我该怎么做?
我所做的:

EmailMessage email = new EmailMessage(service);
email.ToRecipients.Add("TestContactGroup");//Throw an exception "At least one recipient isn't valid."
//email.ToRecipients.Add("TestContactGroup@mydomain.com");//"Return" the mail that "The email address you entered couldn't be found."
email.Subject = "MySubject";
email.Body = new MessageBody("MyBody");
// Send the mail
email.Send();

如果我试图发送到TestContactGroup，我有一个异常:

"至少有一个收件人无效。"

如果我试图发送到TestContactGroup@mydomain.com，我收到一封邮件，邮件没有找到。

那么，我如何向我创建的组列表发送电子邮件呢?或者另一种使用EWS创建分发列表的方法?

谢谢

问题解决了
我只需要添加组id如下:

myContactGroup.Id = grpId;

我得到我的组id如下:
// Instantiate the item view with the number of items to retrieve from the Contacts folder.
        ItemView view = new ItemView(9999);
         // Request the items in the Contacts folder that have the properties that you selected.
        FindItemsResults<Item> contactItems = service.FindItems(WellKnownFolderName.Contacts, view);
        string groupId = string.Empty;
        List<ItemId> groupItemIds = new List<ItemId>();
        // Loop through all contacts 
        foreach (Item item in contactItems)
        {
            //Check to see if ContactGroup
            if (item is ContactGroup)
            {
                //Get the contact group
                ContactGroup contactGroup = item as ContactGroup;
                groupItemIds.Add(item.Id);//Using to send an email by item id, can classify by DisplayName etc..
            }
        }
