如何读取自定义字段值

发布于 2024-12-22 21:45:19 字数 646 浏览 3 评论 0原文

我正在使用下面的代码使用 ews 从我的收件箱中读取邮件。我可以读取主题等。但是如何读取自定义字段值？

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.Credentials = new NetworkCredential("username", "password", "domain"); 
service.Url = new Uri("https://server/ews/exchange.asmx"); 
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(100));

foreach (Item item in findResults.Items)
{
    string str=item.Subject;
    foreach (ExtendedProperty extendedProperty in item.ExtendedProperties)
    { }
}

我尝试了 item.ExtendedProperties。但计数始终为零。谁能告诉我如何读取自定义字段值？

提前致谢

I am using the below code to read the mails from my inbox using ews. I am able to read Subject etc. But how to read custom field value?

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.Credentials = new NetworkCredential("username", "password", "domain"); 
service.Url = new Uri("https://server/ews/exchange.asmx"); 
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(100));

foreach (Item item in findResults.Items)
{
    string str=item.Subject;
    foreach (ExtendedProperty extendedProperty in item.ExtendedProperties)
    { }
}

I tried item.ExtendedProperties. But the count is always zero. Can any one tell me how to read the custom field value?

Thanks in advance

根据这篇 MSDN 文章，您需要将要检索的扩展属性的属性集添加到 FindItems 方法的 ItemView 参数中。

例如，您的行：

FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(100));

变为：

ItemView view = new ItemView(100);

Guid MyPropertySetId = new Guid("{C11FF724-AA03-4555-9952-8FA248A11C3E}");

view.PropertySet = new PropertySet(BasePropertySet.IdOnly, ItemSchema.Subject, extendedPropertyDefinition);

FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, view);

According to this MSDN article, you need to add a property set for the extended properties that you want to retrieve to the ItemView parameter of the FindItems method.

For example, your line:

FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(100));

becomes:

ItemView view = new ItemView(100);

Guid MyPropertySetId = new Guid("{C11FF724-AA03-4555-9952-8FA248A11C3E}");

view.PropertySet = new PropertySet(BasePropertySet.IdOnly, ItemSchema.Subject, extendedPropertyDefinition);

FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, view);
