图片文件如何与文字一起成为邮件的正文？ - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

示例：m.C （p） ontent = "测试邮件文本和图片的混合排版!" + GetImage("C:\Users\Desktop\花瓶\Dra1.jpg")

这个代码提示是错误的，大意是string类型与image类型不能相加，

问题的关键是解决图片文件转为string类型，请求大家帮个忙，谢谢先！

大红袍兄，出现这个问题是什么原因？

“发送失败：命令顺序不正确。服务器响应为：Error：need EHLO and AUTH first！”

代码直接借用您的例子：

Dim client As New System.Net.Mail.SmtpClient()
client.Host = "smtp.qq.com"
client.Credentials = New System.Net.NetworkCredential("451945556@qq.com", "****") ‘是用实际密码,在论坛这里处理了一下
client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network
Dim message As New System.Net.Mail.MailMessage("451945556@qq.com", "kylinchina@163.com")
message.Subject = "图文邮件测试2"
message.BodyEncoding = System.Text.Encoding.UTF8
message.IsBodyHtml = True

Dim body As String = "<html><body>正文内容</body></html>"
Dim content As String

'处理图片
Dim bmp As new Bitmap("C:\Users\Gcell-Kylin\Desktop\花瓶\Dra1.jpg")

Dim ms As new System.Io.MemoryStream()
bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)

Dim arr(ms.Length) As Byte
ms.Position = 0
ms.Read(arr, 0, ms.Length)
ms.Close()

Dim strbaser64 As String = Convert.ToBase64String(arr)

content &= "这是文字"
content &= "<DIV><IMG src='data:image/png;base64, " & strbaser64 & "'></IMG></DIV>"
content &= "也是文字"

message.Body = body.Replace("正文内容", content)

Try
    client.Send(message)
    msgbox("发送成功")
Catch ex As Exception
    msgbox("发送失败:" & ex.message)
End Try

这么用，也出现同样的错误：

Dim client As New System.Net.Mail.SmtpClient()
client.Host = "smtp.qq.com"
client.Credentials = New System.Net.NetworkCredential("451945556@qq.com", "*****") ‘是用实际密码,在论坛这里处理了一下
client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network
Dim message As New System.Net.Mail.MailMessage
message.From = new System.Net.Mail.MailAddress("451945556@qq.com")
message.To.Add("kylinchina@163.com")
message.Subject = "主题测试1"
message.BodyEncoding = System.Text.Encoding.UTF8
message.IsBodyHtml = True

Dim body As String = "<html><body>内容</body></html>"
Dim content As String = "12345678<font size=7 color=red>12345678</font><img src='http://www.foxtable.com/lib/images/banner1a.jpg'/>"

message.Body = body.Replace("内容", content)

Try
    client.Send(message)
    msgbox("发送成功")
Catch ex As Exception
    msgbox("发送失败:" & ex.message)
End Try

谢谢大红袍兄、Hyphen兄的指点，OK了！非常感谢！
