标签: c# outlook

这可能是一个非常初学者的问题。我正在尝试创建我的第一个Windows Forms应用程序,并想通过单击表单上的按钮来创建Outlook电子邮件。

问题是有13个错误,主要是说:

  

严重性代码描述项目文件行抑制状态   错误CS0246找不到类型或名称空间名称'Outlook'   (您是否缺少using指令或程序集引用?)   机器v.0.0.1 C:\ Users \ PC \ source \ repos \ Offer机器v.0.0.1 \ Offer   机器v.0.0.1 \ Form1.cs 29有效

我已添加对项目的引用:

代码如下:

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Button1_Click(object sender, EventArgs e)
        {
            try
            {
                List<string> lstAllRecipients = new List<string>();
                //Below is hardcoded - can be replaced with db data
                lstAllRecipients.Add("sanjeev.kumar@testmail.com");
                lstAllRecipients.Add("chandan.kumarpanda@testmail.com");

                Outlook.Application outlookApp = new Outlook.Application();
                Outlook._MailItem oMailItem = (Outlook._MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);
                Outlook.Inspector oInspector = oMailItem.GetInspector;
                // Thread.Sleep(10000);

                // Recipient
                Outlook.Recipients oRecips = (Outlook.Recipients)oMailItem.Recipients;
                foreach (String recipient in lstAllRecipients)
                {
                    Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add(recipient);
                    oRecip.Resolve();
                }

                //Add CC
                Outlook.Recipient oCCRecip = oRecips.Add("THIYAGARAJAN.DURAIRAJAN@testmail.com");
                oCCRecip.Type = (int)Outlook.OlMailRecipientType.olCC;
                oCCRecip.Resolve();

                //Add Subject
                oMailItem.Subject = "Test Mail";

                // body, bcc etc...

                //Display the mailbox
                oMailItem.Display(true);
            }
            catch (Exception objEx)
            {
                Response.Write(objEx.ToString());
            }
        }

        private void Label1_Click(object sender, EventArgs e)
        {

        }
    }
}

您没有在代码中添加适当的用法。您需要添加:

using Microsoft.Office.Interop.Outlook;

没有这一行,您应该在Interop库中的每个对象之前键入完整的名称空间。使用该功能后,您可以删除所有来自互操作对象的Outlook.。但是创建主Application对象的对象需要完整的命名空间,以避免与Winforms中定义的Application类冲突。

Microsoft.Office.Interop.Outlook.Application outlookApp = 
                   new Microsoft.Office.Interop.Outlook.Application();
_MailItem oMailItem = (_MailItem)outlookApp.CreateItem(OlItemType.olMailItem);
Inspector oInspector = oMailItem.GetInspector;

..... and so on ....

似乎您已两次将Outlook互操作性添加到项目“引用”中。

Outlook automation references

对于错误消息,您只需要向Outlook名称空间添加别名:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

using Outlook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;

此外,您可能会发现C# app automates Outlook (CSAutomateOutlook)示例项目很有帮助。
