我的Office Outlook插件开发之旅(一)

目的

开发一款可以同步Outlook邮件通讯录信息的插件。

VSTO 外接程序对Outlook的支持,是从2010版本之后开始的。
VSTO 4.0 支持Outlook 2010以后的版本,所以编写一次代码,就可以在不同的版本上运行。

COM 加载项十分依赖于.NET Framework框架和Office的版本,之后讲到的时候你就明白。

VSTO 外接程序

VSTO,全称是Visual Studio Tools for Office,在微软的Visual Studio平台中进行Office专业开发。VSTO是VBA的替代产品,使用该工具包使开发Office应用程序变得更简单,VSTO还能使用Visual Studio开发环境中的众多功能。
VSTO依赖于.NET Framework框架,并且不能在.net core或者.net 5+以上的平台运行。

创建VSTO程序

使用Visual Studio 2013的新建项目,如果你使用更新版本的话,那么你大概率找不到。因为被移除了。比如Visual Studio 2019最低创建的Outlook 2013 外接程序

Office/SharePoint -> .Net Framework 4 -> Outlook 2010 外接程序

之后我们会得到,这样的项目结构

打开ThisAddIn.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;
using Outlook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;
using Microsoft.Office.Interop.Outlook;
using System.Windows.Forms;
using System.Data;
using System.Data.SqlClient;
using System.IO;
using System.Threading;
using System.Collections;

namespace ContactsSynchronization
{
    public partial class ThisAddIn
    {
        
        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            // Outlook启动时执行
            MessageBox.Show("Hello VSTO!");
        }

        private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
        {
            // Outlook关闭时执行
        }

        #region VSTO 生成的代码

        /// <summary>
        /// 设计器支持所需的方法 - 不要
        /// 使用代码编辑器修改此方法的内容。
        /// </summary>
        private void InternalStartup()
        {
            // 绑定声明周期函数
            this.Startup += new System.EventHandler(ThisAddIn_Startup);
            this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
        }

        #endregion
    }
}

启动试试看

到这里我们就已经把项目搭建起来了,但在写代码之前不如再认识认识Outlook的个个对象吧。

认识VSTO中常用对象

微软文档
https://learn.microsoft.com/zh-cn/dotnet/api/microsoft.office.interop.outlook.application?view=outlook-pia

常用类型

  • MAPIFolder表示Outlook中的一个文件夹
  • ContactItem 表示一个联系人
  • DistListItem 表示一个联系人文件夹中的群组
  • OlDefaultFolders 获取默认文件类型的枚举
  • OlItemType 获取文件夹子项类型的枚举

全局实例Application上挂载了我们用到大多数函数和属性。

Application.Session;// 会话实例
Application.Version;// DLL动态链接库版本
Application.Name;// 应用名称

Application.Session会话实例,可以获取Outlook的大多数状态,数据。如文件夹、联系人、邮件等。

Outlook文件夹结构

Outlook 按照邮件账号区分用户数据,即每个邮件账号都有独立的收件箱,联系人等。

Outlook 默认情况下的文件夹结构

获取第一个邮箱账号的默认联系人文件夹

Application.Session.Stores.Cast<Outlook.Store()>.First().GetDefaultFolder(OlDefaultFolders.olFolderContacts);

获取Outlook的状态信息

获取联系人信息

MAPIFolder folder = Application.Session.GetDefaultFolder(OlDefaultFolders.olFolderContacts);//获取默认的通讯录文件夹
IEnumerable<ContactItem> contactItems = folder.Items.OfType<ContactItem>(); // 获取文件夹下的子项,OfType<ContactItem>只拿联系人的
foreach (ContactItem it in contactItems)
{
    // 拿联系人的各种信息
    string fullName = it.FullName;
    // 注意在此处修改联系人信息,再Save()是不生效的
}

添加联系人

MAPIFolder folder = Application.Session.GetDefaultFolder(OlDefaultFolders.olFolderContacts);// 获取默认的联系人文件夹
ContactItem contact = folder.Items.Add(OlItemType.olContactItem);// 新增联系人子项
// 设置各种信息
contact.FirstName = "三";
contact.LastName = "张";
contact.Email1Address = "zhangsan@163.com";
// 存储联系人
contact.Save();

删除联系人

Microsoft.Office.Interop.Outlook.MAPIFolder deletedFolder = application.Session.GetDefaultFolder(OlDefaultFolders.olFolderDeletedItems);// 默认的联系人文件夹
int count = deletedFolder.Items.Count;// 获取子项数,包含联系人和群组
for (int i = count; i > 0; i--)// 遍历删除
{
    deletedFolder.Items.Remove(i);
}

打包、安装和卸载

右键项目 -> 发布

发布后你会看到这样的结构

点击setup.exe即可安装了
卸载需要使用VSTOInstaller.exe

"C:\Program Files (x86)\Common Files\microsoft shared\VSTO\10.0\VSTOInstaller.exe" /u "你的.vsto文件目录"
