如何在AlternateView上设置编码

using System.Net.Mail;
using System.Text;

// 创建MailMessage对象
MailMessage message = new MailMessage();
message.From = new MailAddress("sender@example.com");
message.To.Add("recipient@example.com");
message.Subject = "邮件主题";

// 创建AlternateView对象
AlternateView view = AlternateView.CreateAlternateViewFromString("邮件内容");

// 设置编码方式
Encoding encoding = Encoding.UTF8;
view.TransferEncoding = encoding.WebName;

// 将AlternateView对象添加到MailMessage对象中
message.AlternateViews.Add(view);

// 发送邮件
SmtpClient client = new SmtpClient("smtp.example.com");
client.Send(message);
