我从这个问题得到了这个代码：

使用内存流生成 PDF 文件 system.net.mail.attachment

帮助我在内存中创建电子邮件附件。

Imports System.IO
Imports System.Net.Mail
Imports System.Text.ASCIIEncoding
Imports System.net.Mime

Public Sub SendMail(ByVal att As String, Optional ByVal filename As String _
    = "Attachment.csv")

    Dim sendMail As New SmtpClient
    Dim mail As New MailMessage

    Using MemoryStream = New MemoryStream

        If att.Length <> 0 Then

            Dim data As Byte() = ASCII.GetBytes(att)

            MemoryStream.Write(data, 0, data.Length)
            MemoryStream.Seek(0, SeekOrigin.Begin)
            MemoryStream.Position = 0

            Dim content As New Net.Mime.ContentType()

            content.MediaType = MediaTypeNames.Application.Octet
            content.Name = filename

            Dim Attach As Attachment
            Attach = New …

我有以下代码

List<Test> list= new ArrayList<Test>();
list.add(t1);
list.add(t2);
Arrays.sort(list);

Class Test实现了Comparable,但是我在Arrays.sort(list)中得到了错误Arrays类型中的方法sort(int [])不适用于参数(List)
