使用MAPI进行Outlook自定义字段过滤

Question

我尝试在Outlook中过滤自定义属性获取联系人。我保存了用户属性调用＆＃34; SyncValue＆＃34;。它有字符串值。我尝试检查这些值并获得contactitem具有该属性值。

Outlook.ContactItem contactItem = null;
string syncVal = (char)34 + "http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/SyncValue" + (char)34;
Outlook.MAPIFolder contacts = Globals.objNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts);
Outlook.Items contactItems = contacts.Items;
string filter = "WHERE (" + syncVal + " = 'True')";
contactItem = contactItems.Find(filter) as Outlook.ContactItem;

Answer 1

您的过滤字符串必须以@SQL=为前缀。你不应该使用＆＃34; WHERE＆＃34;：

string filter = "@SQL=" + syncVal + " = 'True')";
