c# 使用 POST 和 Mime 发送电子邮件
我正在编写一个程序，我的主管希望我利用他们的内部沙箱电子邮件系统。
本质上，我到目前为止的代码是：
WebRequest request = WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
Stream os = null;
byte[] Bytes = Encoding.ASCII.GetBytes("From: [email protected]\n" + "To: [email protected]\n" + "Subject: test\n" + "jkjlkjkj\n");
try
{
request.ContentLength = Bytes.Length;
os = request.GetRequestStream();
os.Write(Bytes, 0, Bytes.Length);
}
catch (Exception e)
{
Console.WriteLine("error");
}
这工作正常并按预期发送电子邮件。但是如何使用这种方法发送附件呢？它们可能会打开小型小型转储文件。
谢谢。
I am writing a program whereby my supervisor wants me to make use of their internal sandbox email system.
Essentially, the code I have so far is:
WebRequest request = WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
Stream os = null;
byte[] Bytes = Encoding.ASCII.GetBytes("From: [email protected]\n" + "To: [email protected]\n" + "Subject: test\n" + "jkjlkjkj\n");
try
{
request.ContentLength = Bytes.Length;
os = request.GetRequestStream();
os.Write(Bytes, 0, Bytes.Length);
}
catch (Exception e)
{
Console.WriteLine("error");
}
This works fine and send the e-mail as expected. But how can I send attachments using this method? They are likely to open be small minidump files.
Thanks.

如果您使用标准电子邮件协议，只需查找有关如何在电子邮件中发送附件的规范。我刚刚在 PHP 中找到了这个示例，它创建了一条带有附件的消息，也许它在 .NET 中的工作方式相同（更改调用）：
尝试在 Bytes 数组上添加这些行：
Content-Type: application/zip;名称=“附件.zip”
内容传输编码：base64
内容处置：附件
AttachmentContents
其中attachmentContents 是文件的base64 编码转储（显然，根据您发送的内容更改名称和mime 类型。

If you're using a standard email protocol just look for the specifications on how an attachment is sent in an email. I just found this example in PHP that creates a message with an attachment, maybe it will work the same way in .NET (changing the calls):
Try adding those lines on the Bytes array:
Content-Type: application/zip; name="attachment.zip"
Content-Transfer-Encoding: base64
Content-Disposition: attachment
attachmentContents
where attachmentContents is a base64 encoded dump of the file (obviously, change the names and mime types according to what you're sending.
