ASP.NET Web API 异步任务，发送邮件

本文关键字：任务 NET Web API 异步 ASP | 更新日期: 2023-09-27 18:32:21

我的应用程序存在大量性能问题。我发现问题来自发送电子邮件。如何解决该方法RegisterUser返回的问题，而电子邮件的发送仍在进行中？我已经尝试过启动一个线程来运行 SendEmailConfirm 方法，但这给了我一个ObjectDisposedException SendEmailConfirm 

public async Task<IdentityResult> RegisterUser(AccountViewModels.RegisterViewModel userModel)
{
    var result = await _userManager.CreateAsync(user, userModel.Password);
    this.SendEmailConfirm(userModel.Email);
    return result;
}
public async void SendEmailConfirm(string mail)
{
    string subject = "Please confirm your Email for Chronicus";
    string body = "Hello"
    string email = user.Email;
    _messageService.SendMail(mail, subject, body);
}
public void SendMail(string receiver, string subject, string body)
    {
        this._msg = new MailMessage(UserName, receiver);
        this._msg.From = new MailAddress(UserName, Name);
        this._msg.Subject = subject;
        this._msg.Body = body;
        this._msg.IsBodyHtml = true;
        this._smtpClient.Send(_msg);
    }

编辑：在问题中添加了发送邮件方法

ASP.NET Web API 异步任务，发送邮件

您需要使用 SmtpClient 类的 SendMailAsync 方法。

此外，对于不返回任何值的异步方法，应返回Task。

以下是您的代码的外观：

public async Task<IdentityResult> RegisterUser(AccountViewModels.RegisterViewModel userModel)
{
    var result = await _userManager.CreateAsync(user, userModel.Password);
    await this.SendEmailConfirm(userModel.Email);
    return result;
}
public Task SendEmailConfirm(string mail)
{
    string subject = "Please confirm your Email for Chronicus";
    string body = "Hello"
    string email = user.Email;
    return _messageService.SendMail(mail, subject, body);
}

以下是SendMail的样子：

public Task SendMail(string receiver, string subject, string body)
{
    this._msg = new MailMessage(UserName, receiver);
    this._msg.From = new MailAddress(UserName, Name);
    this._msg.Subject = subject;
    this._msg.Body = body;
    this._msg.IsBodyHtml = true;
    return this._smtpClient.SendMailAsync(_msg);
}
