问题描述

我需要使用 EWS 为某些邮件提取 PR_SEARCH_KEY .我之前是使用Outlook API来做的.但是我想用EWS重新编写完整的代码，因为它功能强大.

旧代码:

private String GetLnksForMailBoxMails(Outlook.MailItem mail)
        {
            const string PR_SEARCH_KEY =
                "http://schemas.microsoft.com/mapi/proptag/0x300B0102";

            Outlook.PropertyAccessor pa = mail.PropertyAccessor;
            String searchKey = pa.BinaryToString(pa.GetProperty(PR_SEARCH_KEY));
            //    Console.WriteLine("Here is lnks for normal mail box:{0} ", searchKey);
            return searchKey;
        }

新代码:

ExtendedPropertyDefinition eDef = new ExtendedPropertyDefinition(0x300B, MapiPropertyType.Binary);
                PropertySet prop = BasePropertySet.IdOnly;
                prop.Add(eDef);
                ItemView ivItemView = new ItemView(5000);
                ivItemView.PropertySet = prop;

但是我无法获取它的String值.

解决方案

它是一个Binary属性，因此，如果要获得与OOM中相同的十六进制字符串，只需使用ilke即可返回二进制数组.

ExtendedPropertyDefinition eDef = new ExtendedPropertyDefinition(0x300B, MapiPropertyType.Binary); PropertySet prop = BasePropertySet.IdOnly; prop.Add(eDef); ItemView ivItemView = new ItemView(1000); ivItemView.PropertySet = prop; FindItemsResults<Item> fiResults = Inbox.FindItems(ivItemView); foreach (Item itItem in fiResults) { Byte[] PropVal; String HexSearchKey; if (itItem.TryGetProperty(eDef, out PropVal)) { HexSearchKey = BitConverter.ToString(PropVal).Replace("-", ""); Console.WriteLine(HexSearchKey); } }

private String GetLnksForMailBoxMails(Outlook.MailItem mail) { const string PR_SEARCH_KEY = "http://schemas.microsoft.com/mapi/proptag/0x300B0102"; Outlook.PropertyAccessor pa = mail.PropertyAccessor; String searchKey = pa.BinaryToString(pa.GetProperty(PR_SEARCH_KEY)); // Console.WriteLine("Here is lnks for normal mail box:{0} ", searchKey); return searchKey; }

ExtendedPropertyDefinition eDef = new ExtendedPropertyDefinition(0x300B, MapiPropertyType.Binary); PropertySet prop = BasePropertySet.IdOnly; prop.Add(eDef); ItemView ivItemView = new ItemView(5000); ivItemView.PropertySet = prop;
