Errors when compiling: "Expected class, delegate, enum, interface, or struct"
提问by Cookie Monster
What is wrong with this code? This program is meant to copy a file and email it to a email address, but it doesn't.
这段代码有什么问题？该程序旨在复制文件并将其通过电子邮件发送到电子邮件地址，但事实并非如此。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Net.Mail;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
}
}
public void email_send()
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("your [email protected]");
mail.To.Add("[email protected]");
mail.Subject = "Test Mail - 1";
mail.Body = "mail with attachment";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("c:/textfile.txt");
mail.Attachments.Add(attachment);
SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("your [email protected]", "your password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
}
}
This shows the following compiler errors:

You Method is outside the class for one thing. Copy it into the form 1 class and it should clear up any intellisense issues
你的方法是在课堂之外的一件事。将其复制到表单 1 类中，它应该清除任何智能感知问题

email_send method is not defined within a class.
email_send 方法未在类中定义。
回答by Joel Coehoorn
The email_send()method is outside of the class declaration. It's still inside the namespace, but you must also place it inside the class. Additionally, at no point is the method ever called. It's dead code.
该email_send()方法在类声明之外。它仍然在命名空间内，但您也必须将它放在类内。此外，该方法从未被调用过。这是死代码。
Move the method inside your class definition and then call the method from inside Form_Load()
在类定义中移动该方法，然后从 Form_Load() 内部调用该方法

Exactly what everyone else is saying, but cut/paste this and you should correct the errors:
正是其他人所说的，但剪切/粘贴这个，你应该纠正错误：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.
using System.Net;
using System.Net.Mail;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
}
public void email_send()
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("your [email protected]");
mail.To.Add("[email protected]");
mail.Subject = "Test Mail - 1";
mail.Body = "mail with attachment";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("c:/textfile.txt");
mail.Attachments.Add(attachment);
SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("your [email protected]", "your password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
}
}
}
As you can see, your email_sendmethod is now inside the class declaration.
如您所见，您的email_send方法现在位于类声明中。
