我需要发送包含图片和文字的邮件。我的问题是无法在体内发送图像，它总是出现在底部操作体。

所以我的问题是如何在电子邮件正文中发送写位置图片？

这是不起作用的代码

using System;
using System.Collections.Generic;
using System.IO;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Web;
using System.Net;
using System.Net.Mail;
using System.Threading;
using System.Web;
using System.Net.Mime;
using WindowsFormsApplication5.Properties;

namespace WindowsFormsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void button1_Click(object sender, EventArgs e)
    {
        MailMessage msg = new MailMessage();

        string To;

        To = Properties.Settings.Default.To.ToString();

        msg.To.Add("some.name@gmail.com");
        msg.From = new MailAddress("your.adress@gmail.com");
        msg.Subject = "Subject";

        string path = "C:\\root.jpg"; // my logo is placed in images folder

        LinkedResource logo = new LinkedResource(path, MediaTypeNames.Image.Jpeg);
        logo.ContentId = "companylogo";
        logo.TransferEncoding = TransferEncoding.Base64;

        //now do the HTML formatting
        AlternateView av1 = AlternateView.CreateAlternateViewFromString(
              "<html><body>" + "<p>This will have to be before picture</p>" + "<img src=cid:companylogo/>" + "<p>This will have to be after pictures.</p>" +
              "<br></body></html>",
              null, MediaTypeNames.Text.Html);

        //now add the AlternateView
        av1.LinkedResources.Add(logo);

        //now append it to the body of the mail
        msg.AlternateViews.Add(av1);
        msg.IsBodyHtml = true;

        SmtpClient smtp = new SmtpClient();
        smtp.Host = "smtp.gmail.com";

        smtp.Port = 587;

        //for gmail
        smtp.EnableSsl = true;
        smtp.Credentials = new System.Net.NetworkCredential(
             "your.adress@gmail.com",
             "password");

        smtp.Send(msg);
    }
}
}

我在 gmail 客户端上进行了测试，这是我得到的：
