Question

您好我正在尝试在wpf应用中发送电子邮件但我卡住了; 我显示我的xaml代码

 <Grid>
    <Button     Style="{DynamicResource ShowcaseRedBtn}"  CommandParameter="test@ygmail.com" Tag="Send Email" Content="Button" Height="23" HorizontalAlignment="Left" Margin="351,186,0,0" Name="button1" VerticalAlignment="Top" Width="140" Click="button1_Click" />
    <TextBox Height="23" HorizontalAlignment="Left" Margin="92,70,0,0" Name="txtSubject" VerticalAlignment="Top" Width="234" />
    <TextBox AcceptsReturn="True" AcceptsTab="True"   Height="159" HorizontalAlignment="Left" Margin="92,121,0,0" Name="txtBody" VerticalAlignment="Top" Width="234" />
</Grid>

并且在后面的代码中：

 private void button1_Click(object sender, RoutedEventArgs e)
    {
        Button btn = sender as Button;
        if (btn == null)
            return;
        string url = btn.CommandParameter as string;
        if (String.IsNullOrEmpty(url)) 
            return;
        try
        {
            // here i wish set the parameters of email in this way 
            // 1. mailto = url;
            // 2. subject = txtSubject.Text;
            // 3. body = txtBody.Text;
            Process.Start("mailto:test@gmail.com?subject=Software&body=test ");
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "Error", MessageBoxButton.OK, MessageBoxImage.Error);
        }
    }

我的目的是设置绑定表单中数据的电子邮件的参数： // 1. mailto = url; // 2. subject = txtSubject.Text; // 3. body = txtBody.Text;

你知道如何解决这一步吗？

非常感谢你的关注。

干杯

您可以使用System.Net.MailMessage类直接发送邮件。请查看此类的MSDN文档中的以下示例：

public static void CreateTimeoutTestMessage(string server)
        {
            string to = "jane@contoso.com";
            string from = "ben@contoso.com";
            string subject = "Using the new SMTP client.";
            string body = @"Using this new feature, you can send an e-mail message from an application very easily.";
            MailMessage message = new MailMessage(from, to, subject, body);
            SmtpClient client = new SmtpClient(server);
            Console.WriteLine("Changing time out from {0} to 100.", client.Timeout);
            client.Timeout = 100;
            // Credentials are necessary if the server requires the client 
            // to authenticate before it will send e-mail on the client's behalf.
            client.Credentials = CredentialCache.DefaultNetworkCredentials;

      try {
              client.Send(message);
            }  
            catch (Exception ex) {
              Console.WriteLine("Exception caught in CreateTimeoutTestMessage(): {0}", 
                    ex.ToString() );              
          }
        }

如果您使用的是代码隐藏，则不需要绑定 - 虽然它不是很好的模式，但它当然会有效。

为什么不直接命名文本框（urlTextBox，subjectTextBox等）并在按钮点击事件中使用这些名称？

        Process.Start(string.Format("mailto:{0}?subject={1}&body={2}", urlTextBox.Text, subjectTextBox.Text, ... ));

当然，如果用户输入无效值，这可能很容易失败。

使用绑定是另一种方法，但在这个简单的情况下，我认为它是开销。

我发布了一个类似且更简单的答案here

但重点是

＆＃13;

<Button Content="Send Email" HorizontalAlignment="Left" VerticalAlignment="Top" Height="50">
  <i:Interaction.Triggers>
    <i:EventTrigger EventName="Click">
      <ei:LaunchUriOrFileAction Path="mailto:example@stackoverflow.com?subject=SubjectExample" />
    </i:EventTrigger>
  </i:Interaction.Triggers>
</Button>
