C# 调用outlook 发送邮件 或添加附件发送

1.

这个是不调用IE Mailto 来发送的,调用win API来

Mailto.ShellExecute(0, String.Empty, "mailto:vcool011@hotmail.com?subject=这是标题哦&body=这是文本内容啊！！！！！！！！！ C:\\avatar.xml", String.Empty, String.Empty, 1);

class Mailto                       //与我联系打开邮箱的类
    {
        [DllImport("shell32.dll", EntryPoint = "ShellExecuteA")]
        public static extern int ShellExecute(
         int hwnd,
         String lpOperation,
         String lpFile,
         String lpParameters,
         String lpDirectory,
         int nShowCmd
         );

    }

 

2 调用 IE方法来

           System.Diagnostics.Process.Start("mailto:liuyi.aspnet@163.com?subject=这是标题哦&body=这是文本内容啊！！！！！！！！！");

 

前面二种都不能添加附件发送

下面是可以添加附件发送的

 

3

引用MSMAPI32.OCX 来实现,可添加附件

　　　　　　MAPISession MAPIS1 = new MAPISession();
                MAPIMessagesClass MAPIM1 = new MAPIMessagesClass();
                MAPIS1.NewSession = true;
                MAPIS1.LogonUI = false;
                MAPIS1.DownLoadMail = false;

                string m_path;
                string m_file_name;
                string m_file;

                m_path = "c:\\";

                m_file_name = "Log.txt";
                m_file = m_path + m_file_name;

                MAPIS1.SignOn();

                MAPIM1.SessionID = MAPIS1.SessionID;
                MAPIM1.Compose();

                MAPIM1.AddressResolveUI = true;
                MAPIM1.AttachmentIndex = 0;

                MAPIM1.AttachmentPathName = m_file;
                MAPIM1.AttachmentName = m_file_name;

                MAPIM1.MsgSubject = "The Title ";
                MAPIM1.MsgNoteText = "The Body ";

                MAPIM1.Send(true);

                MAPIS1.SignOff();
