.NET在Office 2010中創建帶有附件的電子郵件

Question

我知道使用mailto鏈接可以打開您的defautl郵件客戶端並填充主題和標題。我需要做類似的事情，但也要附上一份文件。

我的所有用戶都將使用Outlook 2010，並將其設置爲默認郵件客戶端。它只需要爲這種情況工作。

如何創建一個打開Outlook新消息窗口並填充附件字段的電子郵件？

你需要到Outlook COM庫的引用，那麼這樣的事情應該工作：

/// <summary> 
    /// Get Application Object 
    /// </summary> 
    public static OL.Application Application 
    { 
     get 
     { 
      try 
      { 
       return Marshal.GetActiveObject("Outlook.Application") as OL.Application; 
      } 
      catch (COMException) 
      { 
       return new OL.Application(); 
      } 
     } 
    } 

    /// <summary> 
    /// Prepare An Email In Outlook 
    /// </summary> 
    /// <param name="ToAddress"></param> 
    /// <param name="Subject"></param> 
    /// <param name="Body"></param> 
    /// <param name="Attachment"></param> 
    public static void CreateEmail(string ToAddress, string Subject, string Body, string AttachmentFileName) 
    { 
     //Create an instance of Outlook (or use existing instance if it already exists 
     var olApp = Application; 

     // Create a mail item 
     var olMail = olApp.CreateItem(OL.OlItemType.olMailItem) as OL.MailItem; 
     olMail.Subject = Subject; 
     olMail.To = ToAddress; 

     // Set Body 
     olMail.Body = Body; 

     // Add Attachment 
     string name = System.IO.Path.GetFileName(AttachmentFileName); 
     olMail.Attachments.Add(AttachmentFileName, OL.OlAttachmentType.olByValue, 1, name); 

     // Display Mail Window 
     olMail.Display(); 
    } 

對於這個工作，你還需要：

using System.Runtime.InteropServices; 
using OL = Microsoft.Office.Interop.Outlook;
